An electric plane is a complex piece of equipment. Increased demands are placed on its quality and technical characteristics.

Criterias of choice

An electric plane is designed for leveling and sanding wooden surfaces. It is selected taking into account the following parameters:

• blade rotation speed;
• depth of planing per knife pass;
• width of workpiece processing in one pass;
• engine power.

The faster the plane blade rotates, the better the surface of the wooden part is processed. The rotation speed of the knife drum must be at least 10,000 rpm and remain stable as the load increases. A good electric planer provides the ability to adjust this parameter depending on the nature of the work being performed. Effective planing is carried out with a power of at least 350 W. As the length of the blade increases, the resistance of the material increases, so it is better to give preference to more powerful samples.

The length of the cutters affects the planing width. Models with blade widths of 82, 102, 110 mm are often used.

The price of removable blades is low.

The depth of planing depends on how much the knives protrude relative to the surface of the sole. The higher the indicator, the more power is required for comfortable work and to prevent overloads. For domestic purposes, a depth setting of 1.5–3 mm is sufficient.

When purchasing a plane, the quality of the cutting elements and drive belts is also taken into account. Select samples with a dust collector.

The sole must have a smooth surface without defects, recesses for chamfering, and grooves for air removal.

Since working with an electric planer is risky, it is recommended to choose models with the most closed surfaces of the sharp blades.

Almost all well-known brands: Skil, DeWALT, Kraftool, Rebir, Ryobi, Bosch, Zubr, Fiolent produce budget versions of electric planers.

Industrial professional equipment is not cheap; it is advisable to buy it if you plan regular work with increased load. For infrequent use, an inexpensive household tool is suitable.

Nickel-cadmium batteries are accused of a lot of things! They say that the size and weight are large, the capacity and power, on the contrary, are low, harmful to nature, the technology is outdated, the memory effect again... However, neither nickel nor cadmium is in any hurry to give up their position in the power tool market to modern lithium with its trusty ion.

In fact, nickel-cadmium batteries have several undeniable advantages.

First of all, they are cheap.

Secondly, for many people what was said in the first place will be enough.

Thirdly, such batteries are unpretentious, i.e. they can be stored for as long as desired with any degree of charge. If you leave a Li-Ion discharged almost to zero on a shelf in the closet, then after a while it will turn out to be inoperative, you will have to take the device to a repair shop or buy a new one, by the way, for a lot of money. By the way, talk about the impossibility of bringing such “patients” back to life is nothing more than a myth of cunning (or simply incompetent) service specialists: there is a fairly simple method for solving such a problem, but more on that another time. So, NiCd is absolutely not afraid of long-term storage with zero charge.

Fourthly, nickel-cadmium is able to function normally at very low temperatures, even in outer space (and this is not a joke, it is exactly what is used there). Lithium-ion “gives up” already at -5°C, although the most modern models of lithium batteries can withstand up to -15°C, which is also quite warm weather, especially in the northern regions. In the cold, you have to work only with nickel-cadmium. This means he still has gunpowder in his flasks!

Need an introduction

If you are going to test two-speed drills and screwdrivers in the price category from 2500 to 4500 rubles. with NiCd batteries with a voltage of 14.4 V and a capacity of 1.2–1.5 Ah, we pursued several goals at once:

Check what modern relatively inexpensive models are capable of;

Find out how true various statements about the advantages and disadvantages of this technology are;

If possible, confirm or refute some statements regarding nickel-cadmium batteries.

Seven products from six well-known brands took part in the tests: Interskol (two new models at once), Zubr (this copy is also declared as a new product), Stavr, Defort, Hyundai and Stomer (the only professional-class tool that fits into designated price ranges). The characteristics of the presented samples (in ascending order of average cost) are given in tables 1 and 2.

First, let's study the batteries, because this is precisely why the test was started. It would seem that in our age of high technology, manufacturers have long abandoned the use of archaic chargers (chargers) without auto-shutdown and even without an end-of-process indicator, and have also long removed from their range models whose charging lasts an unacceptably long 3–5 hours. Nothing like this! Such apparently historically valuable examples are available from the Zubr, Defort and Hyundai brands. It's time to take a look to table 3.

Myth 1: the longer the better

Manufacturers claim that charging with low current (namely, this is the root cause of the unpleasant “drawn-out” process) increases the life of the battery and allows it to charge better - here we mean increasing the charge density to the possible maximum, in other words, the longer the battery is charged, the more energy it accumulates. This, by the way, is initially untrue, even in theory. NiCd batteries prefer fast charging and slow discharging to zero (or close to it) - this is the ideal mode of their operation, everything else is fiction and a way to reduce the price of the tool by equipping it with the cheapest possible standard charger. Shall we check? Well, to calculate the number of recharge cycles, it would take almost a year of hard work around the clock, let’s put this question aside for now. But it’s quite possible to philosophize about the amount of energy accumulated over 3–5 hours.

Let’s not delve into the physics of the process and the nuances of the ongoing chemical reactions; let’s turn to harsh practice. Table 3 clearly shows that the record for the duration of continuous operation without load (56 minutes) belongs to two participants at once - models from Hyundai and Interskol of the new compact C2 series. The first gets a full charge in 5 hours, the second copes with the same task in 1 hour (plus or minus a couple of minutes). And if you can’t see the difference, why charge longer?.. And even sit next to the chronometer in your hands: there is no auto-shutdown, and leaving a nickel-cadmium battery in the charger for more than 8 hours is categorically not recommended - it will deteriorate (tested on my own experience).

Let’s take a look at a couple of the shortest-lived samples – “Bison” and Defort, which worked idle for 36 and 35 minutes, respectively. Yes, everything is clear here: the batteries have a lower capacity (1.3 and 1.2 Ah) than those of other drills and screwdrivers presented. But if you introduce a correction factor and, using simple mathematical operations, recalculate the operating time of these two participants as if they had 1.5 Ah batteries, then when tested without load, the Zubr will still remain in honorable penultimate place, and Defort will rise to 3rd position from the end of our unique ranking. What changed? Almost nothing.

It remains to deal with “Stavr”, also included in the list of the “shortest” workers: a 1.5 Ah battery rotated its spindle for only 36 minutes. The secret lies in the fact that in addition to the actual amount of energy accumulated in the battery, the operating time of the tool is influenced by the efficiency of charge use, the design of the gearbox and a bunch of other factors. Cheap electric motors with low efficiency (they consume per ruble, rotate for a penny) have not yet been canceled, as well as microscopic savings on lubrication in the gearbox. Obviously, exactly the same situation arose with “Stavr”, and the following fact can serve as proof: the temperature on the metal (I wonder why?

to dissipate heat?) the rear clutch of the chuck of this drill-driver, after a little more than half an hour of “buzzing” at idle, rose above 60 ° C - measured with a contact thermometer. This means that the spindle gets very hot.

Diagnosis? Complete lack of lubrication in the mechanism, there are no other versions. Now the low duration of continuous operation on a single battery charge becomes clear: the lion's share of the energy accumulated there is wasted in order to overcome the friction force in the “dry” gearbox. I would like to give a caustic comment, but perhaps it will be unnecessary.

Thus, in the case of the 7 presented models of drills and screwdrivers, myth 1 can be considered dispelled.

Myth 2: you need to “rock it”

There is a belief among users of cordless tools that a new battery definitely needs to be “boosted”, that is, until it goes through three full charge/discharge cycles (some say five or even seven - who has more?), “banks” will not reach maximum capacity. Moreover, this condition is especially relevant for nickel-cadmium. Yeah, let's check it out.

The technology is simple: we take the battery supplied with each test participant, completely discharge it, charge it again and record the operating time of the tool while it is idle, repeat the procedure exactly 10 times and enter the results (rounded to 1 minute) to table 4.

The myth again split against the harsh truth of life. Absolutely new batteries, taken out of a sealed package, flatly refused to “sway” after three, five, and even seven cycles, and the eighth, ninth and tenth control attempts only confirmed what was said. Skeptics will note that the duration of work without load is not an indicator at all and does not prove anything at all! Let’s not argue, because we still have in stock the second, still completely new, batteries from almost every (except for the Zubr) set, right? Let this trump card lie in your sleeve for the time being and appear when the time comes for testing under load.

Summary: Myth 2 was not confirmed; the capacity of nickel-cadmium batteries does not change significantly during the “boosting” process.

Myth 3: rapid self-discharge

It is estimated that unused nickel-cadmium batteries lose about 20% of their charge per month. This information, although it does not particularly sin against the truth, is still very approximate and general in nature. The speed of self-discharge depends on many factors, including the manufacturing quality of each cell individually and the battery as a whole, as well as the conditions of its storage. As strange as it may sound, the colder it is, the slower NiCd batteries drain. If we assume that the above 20% per month is lost at room temperature 25 ° C (apparently, this is the case), then, for example, at 0 ° C the charge will disappear approximately twice as slow. Hence the advice: abstract from the comments of numerous “experts” from Internet forums (links to personal experience are good because you can’t check its presence in any way) and store the nickel-cadmium tool in the cold, which it is not afraid of anyway.

In theory, an “ideal”, i.e. absolutely sealed, never used NiCd battery of the highest quality loses a little more than 10% of its charge in the first month of storage at a temperature of 20 ° C, after two months - almost 20%, after three - about 25 %, after six months - from 35 to 40% (everywhere we mean from the initial level). As you can see, the self-discharge process is not at all linear. But this is in theory, but what in practice?

Unfortunately, there was not the slightest opportunity to extend the testing for six months or at least three, or even two months, in order to provide more or less accurate data on the ability of nickel-cadmium batteries of specific models to retain a charge. We had only two weeks at our disposal, one of which had to be spent testing the presented tool for a number of other parameters. For the remaining 7 days, the fully charged batteries lay peacefully on a shelf in a room at a temperature of 25 to 28 ° C, at the end of the specified period they were connected to the appropriate drills and screwdrivers, after which the devices were tested for continuous operation. Results - in table 5.

There were outright outsiders here: the battery of the “Stavr” model had the highest level of self-discharge, followed by a small margin by the participant under the “Zubr” brand. The remaining copies showed approximately the same results, and the leaders of the rating were Hyundai and Interskol compact series C2. However, it is impossible to draw any final conclusions from the results of a single attempt - well, perhaps, except for one thing: nickel-cadmium batteries do have self-discharge, and it is significant. Thus, myth 3 turned out to be absolutely true. Well, in the sublunary world there is and never has been anything ideal.

Myth 4: memory effect

Unfortunately, this is not fiction. Nickel-cadmium does suffer from memory effects. The most successful and accurate definition of it is as follows: reversible loss of battery capacity as a result of violation of the recommended charging mode. The bottom line is that NiCd batteries cannot be recharged; before installing them in the charger, they should be completely discharged and cooled down - this, by the way, is a prerequisite; let them “rest” for at least 20–30 minutes, depending on the ambient temperature. However, the manifestation of the memory effect during the tests was not studied in any way, so we will leave it without comment.

Read the operating instructions for drills and screwdrivers, the section “Charging batteries” or something like that.

Everyone to the stand!

It's time to arm yourself with measuring instruments and see how true the technical characteristics of the tested drills and screwdrivers declared by the manufacturers are. All results obtained are included in table 6, and the real values ​​of torque, which many brands love to overestimate, are additionally presented in diagram 1. By the way, the stand for measuring this parameter was kindly provided by the SBM Group Rus company.

Models from Zubr and Stavr again disappointed, not even close to confirming their theoretical 28 and 23 Nm, respectively.

In addition, the Stavr also has idle speeds lower than promised - apparently for the same reason as the lack of lubrication in the gearbox. The manufacturer of the Defort drill-driver slightly underestimated its actual weight, although only by 80 grams, which is extremely insignificant. The torque confirmed in practice for Stomer turned out to be as close as possible to the declared one, and other manufacturers, obviously, in the specifications indicated not the “hard” but the “soft” value of this characteristic, hence the noticeable discrepancy, however, in the right direction: they expected less, got more .

From numbers to screws

The rather high developed torque openly provoked testing in operation under extreme loads. Given: pine beam 100x150 mm and three dozen screws (caps) 8x150 mm with hex heads for seventeen.

Task: to find out whether the presented drill-screwdrivers are capable of driving such powerful fasteners into the specified piece of wood without preliminary drilling, which, admittedly, they are not designed for tightening (see the operating instructions for each model), and if so, for how many screws Is one battery charge enough? The answer is in table 7.

Actually, no surprises happened. “Stavr” habitually failed this test, “Bison” seemed to have started well, but quickly lost torque and after the 7th wood grouse it stopped coping with the task, although there was clearly still some charge in the battery. The Defort model was enough for 14 screws, but let us remind you that it has the least capacious battery (1.2 Ah): if you enter a correction factor and perform a couple of simple manipulations with the calculator, it turns out that with a capacity of 1.5 Ah this participant would have screwed in 17.5 capercaillie, coming very close in results to the Interskol DA-10/14.4M2 model with its 18 pieces. Pure theory, of course, but very similar to the truth. But the three leaders (Hyundai, Stomer and Interskol DA-10/14.4С2) are ahead of the other contenders by a noticeable margin, and you can’t argue with that.

And now the promised trump card from the sleeve. The fact is that during extreme tightening of wood grouse, both batteries were used from the kit of each drill-driver (“Zubr” was an exception): one “boosted”, and the second – completely new, charged for the first time. In both cases, the number of “defeated” screws was almost the same, with an extremely insignificant difference. For example, Hyundai tightened the 26th screw on the first battery to about halfway, and on the second (new) battery almost to the very end, only a little more than a centimeter was missing. A similar picture was observed with the Interskol DA10/14.4M2 model, and the remaining participants showed the opposite result, when the first battery worked ten seconds longer than the second under load. This once again proves that there is no need to waste time and specifically “boost” the nickel-cadmium batteries of a newly purchased tool; no noticeable effect will follow.

Who is better?

Despite a certain external similarity and a slight difference in cost, it is hardly possible to call the presented models the same. The Stavr and Zubr drill-drivers have frankly “inflated” technical characteristics; moreover, work under load for both of them was accompanied by the appearance of smoke from the ventilation holes in the area of ​​the electric motor, as well as a noticeable smell of burnt plastic and overheated insulation. To avoid disappointment, it is better not to mess with these products.

A couple of models showed average results - we are talking about Defort and Interskol DA10/14.4M2. By the way, after tightening the specified number of screws, they retained a significant torque, but not enough to effectively tighten 8x150 mm fasteners without pre-drilling, which, however, will most likely never be required from 14.4 V nickel-cadmium cordless drills and screwdrivers . In general, these specimens are quite worthy of consumer attention, and their prices are attractive. Finally, the three obvious leaders are Interskol DA-10/14.4C2, Stomer and Hyundai, undoubtedly the best models among the presented specimens, maintaining maximum torque until the battery is almost completely discharged, which indicates the most efficient use of charge. Very well made models, supplied in convenient cases and definitely recommended for purchase by DDD magazine.

The main parameters that you should pay attention to when choosing a tool are power, impact energy, ease of use and reliability. For a tool used in everyday life, it is recommended to choose a hammer drill that has at least three operating modes. And, as a rule, it is worth paying attention to the presence of a protective coupling and adjustment of the shaft rotation speed.

The best cordless hammer drills

Very often, buyers are interested in the portability of the tools they purchase. This is understandable, because it is not always possible to connect to a power source, and when doing work in different rooms, you don’t want to constantly carry a huge cable with you, connecting it to different sockets. An excellent solution in this case would be to purchase a convenient and lightweight battery-powered hammer drill. Their capabilities, power and autonomy are quite enough to perform most of the work required by the average user. At the same time, the price of such devices does not go beyond reasonable limits.

1. Makita DHR242Z

One of the best cordless hammer drills not only on our list, but also on the market is the DHR242Z model from the Makita brand. It is equipped with electronic speed control and an excellent anti-vibration system, and the maximum frequency and force of impacts when operating in the corresponding modes is 4700 and 2.0 J. However, the number of revolutions at idle is not too high - only 950 per minute. This is the lowest rating in the rating, and you need to pay attention to this nuance before purchasing. In order not to interrupt the operation of the hammer drill, it is recommended to buy two batteries - the operating time with one is just enough to charge the second.

Which hammer drill is better to buy?

The above rating of the best hammer drills, which are reliable for home and professional work, will help you decide on the optimal choice. The power tools reviewed in our rating are distinguished by their excellent quality and excellent functionality. Among them you can choose inexpensive budget models, professional hammer drills, as well as battery-powered devices that provide maximum mobility and convenience.

An electric plane is a technically complex tool that poses a danger to unskilled hands. The better and more functional the model, the higher its cost. It is worth purchasing a tool if you are starting to build your own home. Buying untreated boards and planing them yourself will be much cheaper. For a professional, the advantages of an electric tool are known; there is no mistake in choosing the manufacturer.

Tool selection criteria

The purpose of the tool is to create a smooth, leveled plane. To achieve the desired result, an electric planer must meet the following requirements:

• rotation speed of cutters;
• planing depth per pass;
• width of the treated surface;
• motor power.

The faster the knife drum rotates, the cleaner the surface. The rotation speed of the knives must be at least 10,000 rpm, and not fall depending on the load. The higher the rotation speed, the higher the surface finish. Professional electric planers from Bosch and other well-known manufacturers have electronic power control with a constant speed.

The ancestor of modern electric planes were manual wooden ones, which are still alive today. They still do wonders in the hands of cabinetmakers today, and according to the work they perform they are called zenzubel, end zenzubel, tongue-and-groove, tongue-and-groove, and additional.

The effective power indicator is 2-2.5 times less than the nominal one. Planing requires at least 350 W. As the length of the knives increases, the resistance of the material increases. When choosing a tool, it is wise to buy a more powerful model. Gentle working conditions will increase the service life of the electric planer.

The planing width in one pass depends on the length of the cutters installed in the drum. Standard knives have sizes of 50,75,82,102,110 mm. Typically, a tool with a blade width of 82,102, 110 mm is purchased. The blades are removable, inexpensive, the most budget ones are 82 mm. It is optimal to purchase electric planes with a planing width of 110 mm.

In order for the entire workpiece to be processed equally, first you need to press harder on the front handle, and finally on the back. You can take the workpiece in length with a margin, and after processing, cut off the edges from the ends.

How thick a layer of wood can be removed in one pass depends on how high the cutters protrude above the level of the cast base. The greater the depth of immersion, the greater the power of a manual electric planer is required. Household tools are rarely set to a depth of more than 3 mm due to the danger of clogging the chip removal pipe. The smaller the cross-section of this hole, the shallower the depth the device is designed for.

The quality of knives and belts in the drive is considered to be significant indicators of operational efficiency. The presence of a dust collector will simplify cleaning at the end of work. The sole of the plane should be flat, but have recesses for chamfering, and have grooves invisible to the eye, but felt by the fingers for air removal.

Before you finally choose an electric plane, you need to clarify the possibility of purchasing consumables - knives and tool belts of your favorite brand in your region.

Which electric plane is best for an amateur?

For occasional use, it is optimal to choose an amateur series plane. This tool differs in cost. During operation, it is necessary to control the heating of the engine, avoiding the temperature on the housing 60 °C. The quality of an electric planer, like other tools, largely depends on the manufacturer. Bosch amateur tools are much more reliable than those made in China. But even here there is a difference - a device released on a Chinese site under license and under the control of the brand owner or assembled in workshops with a label sticker.

When choosing an amateur manual electric planer at a budget cost, you need to know:

• high-quality household tools are produced by Skil, Ryobi, Bosch in green;
• manufactured in China, but under the name of well-known European and Russian brands, in Russian production facilities;
• made in China without indicating the country of origin, with unclear documentation and crooked stickers.

Even the third option is suitable for one-time use, especially since the price of such products is noticeably lower. If treated with care, even the most inexpensive model will serve its purpose.

Power tools in inexperienced hands are dangerous and can cause injury. When choosing a plane, you need to choose a model with the most closed cutter surfaces. Any repairs and cleaning of pipes must be carried out with blocking from accidental starting.

Many companies produce more expensive electric planers for professionals. They are available to people with average incomes. Industrial machines are expensive and purchasing them is economically beneficial only when working in particularly difficult conditions. They are installed if a professional plane cannot withstand the load.

For amateur use, the length of the blades is limited to 110 mm; the 150 mm electric plane is produced only in industrial configurations.

To summarize what has been said, a gradation common among specialists will help in choosing a tool:

1. Industrial class equipment is produced under the brands Dussa, Protool, Hilti, Milwaukee.
2. A professional plane can be purchased from Bosch, AEG, Makita, Metabo, Hitachi, Kress, DeWalt.
3. Semi-professional electric planes Sparky.

It cannot be said about an amateur instrument that it is bad. Companies Interskol, Zubr, Bort and others produce high-quality products, production is developing, and they can easily compete with well-known brands.

However, the adopted classification also explains the pricing policy in the woodworking tool sector and will help determine which electric plane is best to choose.

Examples of electric planer models

Despite the fact that the Bosch PHO 20-82 hobbyist electric planers, green, are produced at a production site in China, they are of good quality. The planes are balanced. The planing depth adjustment is precise, high-speed rotation makes the surface being processed clean. Models are available with planing widths of 82, 102 and 110 mm. Their price depends on the width of the knives, power and configuration. Models weighing 2.2 kg, power 680 W, with a strip width of 82 cm cost a little more than 3 thousand rubles. Bosch planers are usually equipped with one blade, but the drum rotates at a speed of 19,500 revolutions. The devices have connections for connecting a vacuum cleaner and a container for chips.

The manufacturer of electric planes, Makita, is no less famous among professionals and amateurs. Manufacturers keep the price of tools high, rightly believing that they are leaders in the development of new tools. They are constantly working to improve security. Thus, the Makita 1902 model has a knife length of 82 mm. With a power of 550 W and a weight of 2.5 kg, the device operates at a speed of 16,000 rpm. performs finishing processing of the blade, since the chip thickness is 1 mm. Despite the fact that the tool is declared as an amateur one, it is used by professionals. Knives and belts for planes of this brand can be bought in any remote corner of the country.

Interskol products compete with models of famous brands. In 2009, the company bought a renowned production of woodworking tools in Italy. The company took over the constructors and designers and a full-fledged tool production plant. Therefore, the Interskol R 110 1100M electric plane is created with the latest technology, with a cast aluminum sole. This is the first model with a knife length of 110 mm, based on the P 102 1100EM model.

The weight of the tool is 4.5 kg. It can process surfaces at a speed of 1600 rpm, up to a depth of 3 mm. With a power consumption of 1.1 kW, it cleans 110 mm of surface, has an adapter for a vacuum cleaner, and a pipe for removing chips. In terms of equipment, the tool is not inferior to professional tools; it costs much less, just over 5 thousand rubles.

Electric 102 1100EM is in demand among specialists. The tool is used when producing shaped blanks. Despite the modest speed, only 11,000 rpm, electronic control contributes to obtaining high-quality results. The machine weighs 3.8 kg, makes a cut of 2.5 mm and a bevel of 15 mm. The cost of the instrument is about 4 thousand.

The electric planer Zubr ZR 1300 110 is indispensable in a carpentry workshop. The power of the tool allows you to cut chips with a thickness of 3.5 mm. The high-speed knife at a speed of 16,000 cuts flush even the knots found in the canvas. The electronic system maintains a constant speed under load. The tool processes wood of any density. The rip fence allows you to select the quarter. The depth regulator is combined with the front handle. There is a lock against accidental launch. The plane weighs 7.5 kg. The manufacturer's warranty on the plane is given for 5 years.

The inexpensive electric planer Bort BFB-850-T will become a master’s assistant during the initial cleaning of building material. The cast sole with grooves for removing frescoes lies tightly on the surface of the material being processed. For manual planing there is a second handle. The sole is covered with a protective boot during downtime. Using the bed, you can turn the plane into a woodworking machine. Processing width per pass – 82 mm. Chip thickness up to 3 mm. The rotation speed of the knife drum is 16500 rpm. Planer weight 3 kg, price 3350 rubles.

Video review of popular models of electric planes

Why does choosing a hammer drill put the hobbyist in a difficult position? We most often approach the issue based on a certain budget. Upon closer examination, in addition to cost and power, new criteria for comparison open up. Among others, the location of the drive, the number of operating modes, and this is only a small part of the parameters that should be taken into account. We have compiled a rating of the most reliable rotary hammers for 2019-2020. We hope that you will find an instrument that will become a faithful friend for many years to come.

The chance of choosing the ideal option increases if you remember that externally similar models can differ significantly even in terms of maintenance, despite their power and weight.

Budget tool - for rare jobs

It is advisable to choose inexpensive hammer drills if the intended minor work is not of a permanent nature. In this case, the efficiency of use and service life of the tool will please every amateur.

1. KRÜGER 1400 W - 4490 rub.

The KRUGER electric rotary hammer impresses with its impact-resistant housing and rich equipment. The product is distinguished by its ergonomics and thoughtful design:

• the powerful engine will last a long time and will help solve many household problems;
• several operating modes, DFR and SDS+ cartridges make the tool universal;
• a switch with an accelerator function allows you to smoothly adjust the drilling speed;
• switch lock ensures convenience during long-term operation;
• reverse simplifies working with complex materials;
• an additional handle makes the device more ergonomic;
• The power cable is located where it belongs - it will not interfere with work

The kit includes the hammer drill itself, an additional keyless chuck, an additional rubberized handle and depth gauge, 3 drills, a pick and a drill.

2. Hammer PRT 650 A – RUB 3,999.

If you do not take into account the persistent smell of chemical modifiers responsible for the strength of the plastic, then the capabilities of the PRT 650 A model from Hammer definitely deserve respect. Impact energy and low (but effectively reducing recoil during impact drilling) weight play a huge role in the formation of potential.

Overall, it’s a worthy tool that allows you to hang a chandelier and cornice yourself, knock old tiles off the walls and floor, and secure baseboards.

Theoretically, the PRT 650 A, with its set of bits, should also cope with the transfer of electrical points in the apartment. But, judging by the reviews, chipping on a large scale negatively affects the performance of a budget hammer drill. While infrequent use allows you to count on a fairly long service life.

Among other things, a reluctance to understand the instructions leads to misconceptions about a Chinese-assembled tool. The same well-known “shortcoming” associated with the haphazard disappearance of the impact is caused by the design features of the impact mechanism and appears in those users who allow operation in drilling mode with impact, without load. This problem is not a warranty case and can be “treated” by sharply lowering the drill installed in the chuck once.

3. DeFort DRH-800N-K – 3350 rub.

As the practical experience of the owners shows, the capabilities of this model cover the needs of the average user. The impact energy of 3.3 J and 3.3 kg of weight at low speeds allow you to quickly make holes not only for a picture or for a TV bracket. Even apartment renovations performed with the DRH-800N-K will not take much time.

• 3 drills, a chisel and a pick included, for full operation in each available mode;
• electronic speed control allows you to change the rotation speed (a necessary measure for comfortable work on tiles, bricks and metal);
• the presence of reverse determines the ability to change the direction of rotation of the equipment without loss of power. Allows you to immediately remove a stuck drill;
• spacious plastic suitcase.

This set from DeFort is easy to work with and very easy to store construction tools.

4. Interskol P 22 620 ER – 3443 rub.

Absolutely all the work that you have to deal with in your own home and country house can be done with the Interskol P 22 620 ER rotary hammer. The only thing that can somewhat darken the user’s mood is the 2 operating modes of the tool. But it should be understood that the absence of a chiselling mode is critical for a professional (it is not possible to perform chiselling for wiring and widening openings in reinforced concrete slabs). For an amateur to independently decorate his home and subsequently maintain the premises in a presentable form, the capabilities of the P 22 620 ER are sufficient:

• Adjusting the speed and reverse allows you to abandon the use of a drill and easily remove equipment jammed in concrete.
• Fixing the trigger is responsible for convenience in the process of mixing solutions.
• The safety clutch protects the operator's hands and face from unexpected blows when the drill jams.
• The SDS+ system ensures quick replacement of drills (chisels, picks) in the chuck.

5. BORT BHD-900 – 4168 rub.

The technologies introduced into this horizontal hammer drill make it possible to carry out finishing work indoors at a relatively low cost, without focusing on the material of the walls. This argument is supported by:

• presence of reverse
• key chuck (with SDS+ adapter)
• the presence of three modes (drilling with and without impact, chiselling).

And if you exclude contact of a working drill with reinforcement (for example, using a hidden wiring scanner), then the potential of the BORT BHD-900 model will be sufficient for through drilling of interior reinforced concrete slabs.

Despite the claimed impressive performance, this tool is not intended to work with either unstressed or, especially, impact drills. In everyday conditions, the same sub-sieves are drilled with a small-diameter drill in a circle, after which the resulting “sieve” is broken with a chisel.

6. Hyundai H 850 – 4503 rub.

The model, initially positioned as a household tool in the middle price segment, can only formally (because it costs up to 5,000 rubles) be classified as a budget hammer drill. Indeed, thanks to the presence

• reverse,
• 3 full-fledged operating modes and an additional function that expands the chiselling capabilities,
• electronic speed control (trigger),

This device is capable of not only chiseling and drilling, but also drilling quite well. The ability to lock the spindle for a “clean” blow in a certain position (the 4th function, which with drilling options is immortalized by a massive bas-relief “4 functions”) - brings the Hyundai H 850 as close as possible to a consistently popular middle-class tool.

It is known that domestic consumers have a negative attitude towards the drills that come with this model. But here it should be understood that this equipment is a consumable material, even if it is not of very high quality. And coupled with a relatively short power cable and a mediocre case, this manufacturer’s approach can be regarded as an excellent attempt to reduce the cost of the kit without significantly compromising the quality of the tool.

Middle class - a reliable tool for amateurs and professionals

No category of construction power tools is as popular as middle-class rotary hammers. After all, the opportunity to hold in your hands the products of world-famous companies, as well as the ratio of cost and potential, do not leave either amateurs or professionals indifferent.

7. Bison Salary 900 EK – 5100 rub.

Based on the design features and thanks to the set of implemented technologies, the Zubr ZP 900 EK hammer drill is considered to be an analogue of expensive professional equipment. After all, there is everything here that is somehow implemented in a branded tool.

• Keyless chuck (SDS+) with dust protection,
• metal housing of the impact mechanism,
• sophisticated anti-vibration system,
• the handles are made of materials that prevent the tool from slipping during operation,
• 3 standard operating modes,

reinforced by a small 5 kilograms of weight and a vertical position of the electric motor, they bring the ZP 900 EK to the level of a good household tool. Even with a claim to professional use. After all, for this model, the loads are not critical either when working with a drill with a diameter of up to 28 mm, or with non-impact bits, or during the chipping process.

8. DeWalt D25103K – 7031 rub.

Thanks to the price of the D25103K horizontal rotary hammer, the potential of professional equipment has become accessible to the average amateur. This means that independent performance of a wide range of repair and finishing work will not be overshadowed

• frequent engine overheating, requiring prolonged rest
• unstable operation of the impact mechanism (due to design features and, at the same time, an easily solvable problem in most models of inexpensive tools)
• injuries received during operation.

The reasons for this are, respectively:

• low shaft speed
• design features of the impact bolt that prevent it from jamming when operating without load
• the presence of a safety clutch that stops the transmission of torque to the shaft immediately when the drill, chisel or lance is blocked.

Thus, domestic consumers will never lose interest in a decent branded instrument, even if it is made in China (affects only the final cost).

9. Bosch PBN 300 FRE – 7068 rub.

Like most mid-range models, the PBN 300 FRE comes in a plastic case, with an auxiliary handle, a depth stop, a set of branded bits, a chisel and a quick-release chuck for regular drills. But such possibilities as:

• work with crowns (up to 68 mm in diameter), which allows you to minimize the time for preparing places for sockets and switches;
• adjusting the number of revolutions, which makes it possible to avoid chipping the plaster when drilling, and correctly (without aerating the solution) mix 20-25 kg of dry mixture with water;
• safety clutch, which reduces the risk of injury if a drill or bit gets jammed during operation of the tool,

and others, indicate that this hammer drill belongs to the professional models. And only the price reminds you that this is a middle-class instrument. Theoretically, this is the possibility of long-term use in domestic conditions. But in fact, domestic professionals use such a tool quite often. Since, with a proportionate load and timely maintenance, even the “green” series from Bosch is capable of showing decent results throughout its entire service life.

10. AEG KH24E – 7300 rub.

The 2009 restyling did not affect the appearance of the KH24E; the main changes were made to the “filling” of the instrument. For example, in the updated models the impact force was slightly reduced, which increased the accuracy and duration of work. Thanks to this, this hammer drill is suitable

• amateur, because in order to use the full potential of the model, it will take more than one year and a wide range of interests (the manufacturer allows work on wood, metal, concrete)
• a professional who will come up with the need for the first maintenance in about a year (the service life of the new KH24E has increased due to the reduction in power).

At the same time, each of them will appreciate the elastic coating of the handle, the ability to adjust the speed by pressing the trigger, and the presence of a quick-release chuck with a shank included in the kit.

11. Makita HR2470 – 7469 rub.

The ease of working with Makita horizontal rotary hammers, proven in practice, is also inherent in the 2470 model. Relatively low weight with sufficient impact force and smooth adjustment of shaft speed are successfully complemented by comfortable handles with anti-slip coating and a full range of operating functions

The existing ability to fix the bit in one of 40 preset positions reduces labor intensity and increases the accuracy of the chiselling process.

The SDS+ system ensures quick drill replacement. The permissible parameters of processed wood, steel and concrete fully cover the needs of home or country repairs. Therefore, model 2470 is in demand not only by amateurs, but also by professionals specializing in finishing work.

Professional tool – precision and comfort in work

The high cost of a professional power tool does not imply its ability to withstand extreme loads. It guarantees only precision in every process, ease of use in any situation and a long service life.

12. Makita HR2450FT – 7948 rub.

While similar in appearance to other models in this line, the 2450FT rotary hammer differs in that its potential is worthy of professional use. This is supported by:

• permission to work with crowns with a diameter of up to 65 mm
• optimal ratio of power and impact frequency for finishing work
• presence of work area illumination
• system for quick replacement of the SDS+ chuck with a quick-release chuck for a conventional drill
• the presence of a safety clutch and anti-slip inserts under the arm.

The implementation of the reverse function in this model also deserves special attention - when switching the direction of rotation, a mechanical limitation of the trigger displacement occurs. Due to this, the reverse rotation speed does not exceed half of that declared by the manufacturer.

14. Hitachi DH24PC3 – 8876 rub.

Professionals claim that the accuracy of the Hitachi dh24pc3 rotary hammer is ensured not only due to a synchronous increase in the impact frequency and shaft rotation speed.

• Correct tool balancing
• light weight
• ergonomic handles with rubber inserts
• convenient control of three operating modes and reverse function,

also have a significant impact on the precision of the workflow.

The absence of any drills or additional cartridges in the package is another point that indicates that the hammer drill is intended for professional use. All necessary equipment is always purchased for a specific type of work. Therefore, Hitachi dh24pc3 is equipped with only a spacious suitcase, an additional handle and a drilling depth limiter.

15. Bosch GBH 2-28 DFV Professional – RUB 10,495.

• quick cartridge replacement,
• fixing the bit in any position,
• reduction of tool vibration,
• blocking torque without stopping the engine when the nozzle jams.

It should be remembered that the configuration of this hammer drill will suit only professionals. Because the absence of a drill, chisel or pick is not critical for this category of craftsmen. Each has its own specifics of work, and therefore its own set of equipment. But from a set of

• 2 quick-release chucks (one for drills, with a smooth shank, up to 13 mm in diameter, the other with an SDS+ clamp),
• drill limiter 210 mm,

16. Interskol PA-10/14.4R-2 – 7529 rub.

The modest capabilities of the PA-10/14.4R cordless hammer drill (drilling with and without impact) are compensated by its minimal dimensions and sufficient impact energy. According to practicing professionals, this combination of performance characteristics allows high-quality holes to be made in wood, metal and concrete.

• A pair of batteries is enough to work without long breaks for recharging (the potential of one is 25 holes 8x50 mm).
• The electronic motor brake prevents the drill or drill from rotating due to inertia. Stopping the rotation the moment the master releases the trigger.
• The backlight helps you see possible mistakes when drilling in poorly lit or hard-to-reach places.
• A three-section indicator indicates the current battery charge level.
• The convenient shape of the hammer drill allows it to be placed in a belt holster.

All devices necessary for full operation of the PA-10/14.4R-2 are placed in a small case. Therefore, users have no problems with either storing or transporting the cordless tool.

Editor's Choice

Despite the objective difficulty of choosing the best model, it is worth noting the capabilities of the Hammer PRT 650 A - its low cost and decent performance distinguish this instrument from its closest budget-class competitors.

In the middle price segment, the Makita 2470 and AEG KH24E will cope equally effectively with the needs of amateurs and the demands of specialists. Some will certainly be satisfied with the current price of branded models, while others will make a choice based on its potential.

Any task related to the repair and decoration of premises can be accomplished by every rotary hammer from the professional segment. But those who make money in construction consider accuracy and ease of use, rather than versatility or price, to be the basis for choosing the right tool. From these positions, compliance is observed with both the Hitachi DH24PC3 and the Bosch GBH 2-28 DFV Professional, and the battery-powered Interskol PA-10/14.4R-2, as a lightweight “dowel rod”, is generally beyond competition.

Summary

No matter how attractive this or that model may be to you, you should not make quick conclusions. Only a thorough analysis of your needs and the potential of the rotary hammers available on the local market will determine a worthwhile investment in a construction tool.
