Homemade wood disc. Grinder disc for wood: how to choose the right grinding and cutting wheel? Sawing on plywood and thin wood

It's like the fairy tale about the unicorn, everyone has heard about it, but no one has seen it with their own eyes. The public of construction forums and authors of similar articles on the Internet is divided into two camps. The former say that during their lives they have cut through more than one cubic meter of wood with a grinder, the latter give strong arguments in favor of the fact that after such work you can lose your fingers or limbs, or even worse. Is there a disc for an angle grinder for wood, and if so, what does it look like and is it safe to use?

The author of this article kindly asks you not to consider this material as a guide to action. An angle grinder is not intended for working with wood; even those manufacturers that produce discs and cutters for wood write on their official websites that it is extremely unsafe to cut wood with an angle grinder. But you and I know that people rarely think about their health first.

Cutting with an abrasive disc

Yes, you can cut wood with a metal disc; to be honest, I myself have done this more than once while working at a construction site. What can we say? Well, firstly, the speed of work with this method is low. Secondly, the smell of burnt wood is guaranteed even in the open air within a radius of 10 meters. And thirdly, the thickness of the sawn board should not exceed four centimeters. This is not to say that the abrasive disc is not a wood disc for an angle grinder; its main purpose is to cut metal. As for the advantages, in my opinion these are: the absence of sawdust, and a smooth, even cut.

Circular saw blade and its improved analogue

The vast Internet is full of videos on how to turn a circular saw blade or a diamond blade for concrete into a blade for working with wood. You can argue for a long time about whether this is worth doing or not? Even without considering myself a very smart person, I would not conduct such experiments. And that's why:

  • The circular saw blade is not designed for high speeds; yes, it is carbide, but no less fragile. One chipped tooth can pose a great danger to a person.
  • The edges of the toothed disk are not smooth; when cutting into a tree, the grinder will vibrate and crash into the branches of the workpiece. This type of work may cause the operator to lose control of the tool.
  • the likelihood of a kickback increases

There is an adapted blade for a wood grinder on sale; manufacturers claim that due to the shape of the tooth and special expanders that are located on the cutting part of the blade, all of the above concerns about the tool jamming disappear. One of the manufacturers is the Rotarex company; in its assortment you can find both grinding and cutting discs for grinders. Below is an image of a circular saw disc and a grinder disc from Rotarex, which is universal. They can cut not only wood, but also aerated concrete.

Chain disk for wood for an angle grinder

At first glance, it may seem that this is a device for a horror film, but judging by the reviews of its owners, this disc is safer than the analogues presented above. It is a solid circle, along the edges of which there is a chain from a chainsaw, everything is made of high-quality tool steel. The main purpose of such a disk is: milling, modeling, stripping wood of bark and cutting out cups in logs for log houses. It is also possible to cut with such a disk, given that the cutting width will be about eight millimeters, since the thickness of the chain disk is six millimeters. Speaking of diameters, there are 125 and 230 wheels on sale. The service life of such a disk will be many times longer than that of others, since it can always be sharpened with a file. The price for them ranges from two to three thousand rubles, and with delivery from another region it will cost even more.

Remember safety!

No matter what kind of disc you work with and no matter what material you cut, you should always remember that following safety rules can save not only your health, but also your life. And before you start working, read the following points:

  • do not work while intoxicated;
  • use safety glasses and protective clothing when working;
  • Do not remove the protective cover under any circumstances;
  • It is prohibited to use a faulty cutting disc or a disc with any, even minor, defects;
  • When working with an angle grinder, hold it with both hands;
  • the electrical cord must be kept away from the rotating disk;
  • Do not put down the tool until the disc comes to a complete stop.

There are a lot of ways to cut wood, one of them is to make a cutting disc out of paper. How effective this is, of course, is up to you to judge, but please note that this is one of the safest options.

The grinder, being a universal tool for a home craftsman or professional, is used to perform many operations such as cutting materials, grinding, peeling various surfaces, etc. Sooner or later, every owner of this tool asks the question: is it possible to work on wood with an angle grinder, and what attachments are needed for this?

The only operations with wood that can be performed with an angle grinder (angle grinder) without danger are grinding and roughing, and then using special attachments. Of course, you can cut wood, but it is strictly prohibited! The Internet is full of shocking photos showing what can happen when using an angle grinder as a cutting tool for wood.

The main arguments that can be made against using an angle grinder for sawing are as follows.

  1. This machine is not designed for sawing wood.
  2. Since wood has a viscous and soft structure, the saw blade can jam in it. As a result, the grinder is often pulls out of hands, and it flies in an unpredictable direction (in the leg, along the arms, in the stomach, etc.), causing deep wounds to a person or amputation of fingers. Even fatal cases have been reported.
  3. When cutting wood it happens very quickly heating the saw blade, causing it to begin to lose strength. The slightest misalignment or excessive pressure may cause it to fly apart. Since the spindle speed of an angle grinder is high, tool fragments fly away at the speed of shrapnel and penetrate deeply under a person’s skin. The user will be lucky if the fragments do not fly into the head or eyes.
  4. Despite the dangers of using saw blades with teeth, some angle grinder users ignore this fact and continue to install compass disks with large teeth or improved with carbide tips. If, when cutting wood, a hard knot or nail residue gets caught in it, the tooth or solder breaks off, gets caught by the next saw tooth and is thrown out at the speed of a bullet. One can only guess about the consequences.
  5. Ignoring all the warnings, users of grinders install a circular saw on the machine with a larger diameter than the protective casing. This is the most dangerous option for using an angle grinder.

Based on the above, you can cut wood with an angle grinder only at your own peril and risk, and only if this is a single or infrequent operation.

If you have to cut wood constantly, it is better to purchase a special machine for this purpose, or use a jigsaw. In extreme cases, the grinder can be used as a drive and made into a circular saw, securing the device rigidly to the frame.

What kind of circles are there for cutting wood?

Despite the dangers of using an angle grinder for cutting wood, tool manufacturers still produce saw blades for it.

Circular saws

The photo below shows “dangerous” saw wheel for an angle grinder, although its diameter corresponds to the protective casing of a grinder with a maximum working tool of 180 mm. There are tipped saws with smaller diameters.

In the next photo you can see a less dangerous version of a circular saw. It provides protection against jamming, and is implemented by slightly moving the teeth in different directions.

Chainsaws

A saw blade made using a chainsaw chain reduces the risk of injury if the tool jams. This attachment is designed in such a way that the chain attached to the inner disk (base) has not fixed landing.

If the chain gets stuck in the material being processed, the base continues to rotate and the tool does not tear out of your hands.

These chain discs for grinders have many modifications, and with their help you can trim branches in the garden, and can also be used for rough cutting of thin boards.

In addition to cutting, the chain disk can also be used like a ripper, for example, for removing bark, as well as for cutting cups in logs and modeling.

Saws with few teeth

Also, for grinders, in order to increase the safety of working with wood, tool manufacturers produce cutting discs with a small number of teeth.

Discs of small diameter can have 3 teeth, and large ones - 4, as shown in the following photo.

These grinder blades are excellent at cutting wood both along the grain and across it. In addition, with the help of a saw wheel you can cut grooves, make various cuts and tenons in the workpiece. But when working with an angle grinder, you should adhere to one rule: you need to install a cutting disc on the grinder of the same diameter for which it is designed by the manufacturer, that is, do not exceed its dimensions. Circles of smaller diameter can be installed.

Tungsten carbide discs

Tungsten carbide discs for angle grinders appeared on sale not so long ago and made a kind of revolution in the field of woodworking.

This universal disk has no teeth. Instead of the latter, segments are located around the circumference of the nozzle. The cutting disc is similar in appearance to a diamond wheel for cutting concrete. With the help of a tungsten carbide wheel for an angle grinder, you can very easily saw wood of any hardness and viscosity. In addition, he is not afraid of nails, screws and other metal inclusions that may be in the workpiece on his way.

This is the safest wood saw blade for an angle grinder.

Its price on the Internet is about 700 rubles. But if you consider the possible consequences of using circular saws, then this is a low price to pay for safety.

Wood sanding attachments

For wood processing, in addition to cutting wheels, there are attachments specially designed for installation on angle grinders, with which you can peel, grind, brush and mill wooden surfaces.

Peeling attachments

If you need to remove a layer of paint or other coating from a wooden surface, you can install a sanding attachment on the grinder. There are a large number of different attachments for grinding work available on the market. They differ in shape, design, and types of work that can be performed with this tool.

The photo below shows disc nozzles with thorns or crumbs, with which you can easily remove the top layer of wood, grind down the end of the board, etc.

The next cutter, due to the fact that the tenons on it are located on a flat plane, allows level various wooden surfaces. For example, if 2 boards on the floor at the end joint are at different heights. Using this attachment, the defect is easily eliminated, and the boards are joined in the same plane.

Peeling attachments are also available twisted wire. They can be made in the form of a metal cup with a wire inserted into it.

Or in the form of a disk with turns of wire clamped in its central part.

These brushes are used if you need to quickly remove old paint from a wooden surface or rust and paint from metal.

The next photo shows a brush with a smaller diameter wire, and it is used for finer roughing work on wood and metal.

In addition to cleaning, this brush is often used for brushing wood, that is, giving it an aging effect. If this effect needs to be used on large surfaces, in the professional field, then for brushing it is better to use special hand-held machines with wide brushes.

Grinding and polishing attachments

For grinding various surfaces, including wood, there is a special attachment for angle grinders on sale, consisting of a metal base, onto which it is attached using Velcro emery grinding wheel. The attachment is screwed onto the angle grinder shaft and tightened with an open-end wrench.

It is often equipped with an adapter for mounting in a drill chuck or drilling machine.

A grinding wheel is not used for polishing surfaces. Instead, they are installed on the nozzle felt discs, which are attached with Velcro.

Also often used for sanding wooden surfaces. flap sanding wheel. It is called so because it consists of many petals fixed on its plane, made of sandpaper. The grain size of the latter can be selected based on the requirements for the surface being processed. For rough sanding, coarse-grain sandpaper is suitable, and for finishing sanding, vice versa.

The better way to sand wood - with a grinder or a sander - depends on what you are going to prepare the wooden surface for. If you are applying regular paint, you can use a grinding wheel. If for varnishing, then a grinding wheel mounted on an angle grinder cannot be used, since it will produce small radial scratches on the surface of the wood, which will clearly appear after applying the varnish. In this case, longitudinal grinding is used for grinding. belt sander(the sanding belt moves longitudinally) or vibration, where the same sanding wheels are used.

Safety precautions when working with an angle grinder on wood

If you decide to use an angle grinder as a tool for cutting wood, then you should remember some safety measures that cannot be ignored.

  1. Before installing the tool on the angle grinder, it must be disconnected from the power supply.
  2. Under no circumstances do not remove the protective casing from the angle grinder. This is the only barrier between the circular saw and your skin. In some cases, it will be able to protect your face from flying instrument fragments.
  3. When working with an angle grinder on wood and not only the use of protective gloves is a must.
  4. Do not use large and powerful angle grinders to cut wood. If the saw jams, you will not be able to hold the tool in your hands.
  5. Do not use saw blades with large teeth, as the likelihood of them catching on hard wood fibers increases significantly and, accordingly, the likelihood of the tool being pulled out of your hands increases.
  6. An angle grinder must have speed controller which need to be reduced to a minimum. If there is no regulator in the device, then it is better not to risk your health. As a last resort, you can make a regulator yourself and install it in an extension cord socket.
  7. The grinder should be held strictly at a right angle while sawing. Any slight misalignment can cause the circular saw to collapse.
  8. Under no circumstances should you fix the device’s start button, since in an emergency you will not be able to stop the tool and minimize injuries.

Currently, an angle grinder, popularly known as an angle grinder, is deservedly considered one of the most versatile tools. Almost every good owner has it in his arsenal. With such an assistant, you can quickly and effortlessly cut, grind, polish, peel or saw almost any material with your own hands.

The secret of such unheard of popularity is the simplicity of the instrument. The instructions for the grinder provide for attaching a specific disk or attachment to a rotating shaft.

After which, depending on the purpose of the disk, you can perform certain work. The scope of application can be varied, but in this article we will focus more on cutting and processing wood.

Advice: according to most experts, it can only be used for fragmentary work. Moreover, this must be done extremely carefully, the risk of injury is too high.

General characteristics and purpose of disks

The range of this product is simply huge; there are dozens of types of products in each sector. But all this mass can be divided into several main directions.

Types of disks

  • Abrasive-coated wheels or discs are designed for grinding and polishing various surfaces. Since wood is not polished, a wood grinding disc for an angle grinder is used in this sector.
  • Diamond-coated wheels are more commonly used in construction; they come in segmented and solid types. They are used to cut particularly durable materials, such as stone, concrete monolith and, in some cases, metal. Such products are not used for carpentry work.

  • Saw blades for wood for an angle grinder are visually practically no different from circles for a circular saw. But they are made of a completely different metal. Until recently, these products were rare; now a lot of high-quality tungsten carbide wood wheels have appeared on the market.

Important: under no circumstances even try to install a circle from a circular saw onto an angle grinder. Theoretically, this can be done through an adapter, but circular discs are designed for low speeds and on an angle grinder, in the vast majority of cases, they become warped or simply fly apart.

  • Regardless of their purpose, all circles have several standard diameters. The smallest wood disc for an angle grinder is 115 mm. But the most popular is considered to be a 125 mm wood disc for an angle grinder.

  • Wood is a specific material, so you should not use circles designed for cutting concrete or metal.. These materials require high strength and high speed; such a circle can simply get stuck in wood, which will lead to its destruction or burn your grinder.
  • The shaft diameter in all modern angle grinders for wood is standard and is 22.2 mm. But, in the recent past, there have been several gradations, so you should pay attention to the labeling. For example, a wood saw blade for an angle grinder 125x22.2 mm can be installed through an attachment on the thin shaft of an outdated machine, but if the shaft is thicker, your circle will be useless.

Important: the maximum diameter of a manual angle grinder is 230 mm. So, even if you manage to find a wood cutting disc for a 230 mm angle grinder, it is better to refuse its installation and use. The fact is that the larger the diameter, the higher the likelihood of injury, especially when working with wood.

Cutting wheel

Due to the fact that this tool has high speeds and cannot be firmly fixed in the hands, high-strength tungsten carbide is used for such circles, which is why their price is respectable.

A cutting disc for wood for a 125 mm grinder is classified not only by diameter and, accordingly, depth of cut, but also by shape, frequency and number of teeth.

During long-term use, carbide-tipped circular saws sometimes lose their initial properties. However, this does not mean that you should get a new cutting tool. Almost always sharpening is done on your own, using any suitable machine.

At the beginning, you should decide whether it is necessary to do sharpening, as it is also called no. There are several obvious signs indicating the relevance of this procedure. If you ignore them, then in the near future the disk will be beyond repair and will serve as a prerequisite for the failure of the expensive machine.

The advantage of gaming slots for using a saw blade with soldering is to increase the service life. It is also designed for processing hard wood species. Surfacing is made from steel 9ХФ, 50 ХВА, 65Г and similar compositions. They are distinguished by their highest hardness; however, with significant use, the possibility of their breakage will increase.

Carbide teeth are made in accordance with GOST 9769-79. But their geometry and geometric dimensions are determined by the manufacturer based on the purpose of the saw. If there is no template, you need to find the required sharpening angles on your own. For this purpose, you are recommended to use a pendulum inclinometer.

Development of template production in-house.

  1. Take a new disc with soldering, which is quite similar to the dull one.
  2. Draw clear outlines on a hard sheet of cardboard.
  3. Using a pendulum goniometer, find the initial geometry of the carbide tips.
  4. Enter the data on the template.

Additionally, it is recommended to compare the acquired data with the reference data. In saws for longitudinal cutting, the front angle is usually 15°-25°. For transverse models, this popular rumor ranges from 5° to 10°. In universal models, the frontal angle is 15°.

It is important to keep in mind that you will like the front angle to be negative. Similar models are used for cutting plastic sheets and non-ferrous metals.

To form a new cutting edge, use any sharpening machine. It is important to first choose the right sanding wheel and sharpen the edge when using it. For this purpose you need to use corundum or diamond models.

A good option is to use special equipment designed to do this job. Unfortunately, due to its high price, in some cases its purchase is impractical. Another method is to introduce a grinding machine with the ability to configure the angle of the corundum disc.

Under no circumstances should you sharpen by hand yourself. That's it - it will take a lot of time. Secondly, the acquired result will not meet the standards. For which the design is intended, the inability to sharpen a saw blade on wood without the help of others is recommended using tips from specialized companies.

Professional sharpening of circular saws is carried out independently according to the following rules:

  • the main deformation occurs at the upper edge of the tooth. The edges are rounded from 0.1 to 0.3 mm. From this place you need to start processing;
  • sharpening is carried out along the front and rear edges. This will ensure the possibility of repeating the procedure up to 25 times;
  • the removal amount should not exceed 0.05-0.15 mm;
  • The level of processing of the front and rear edges must be similar.

If the sharpening of wood discs ends, it is recommended to finish it with fine sandpaper. This is done manually, as it is also called, using a special machine.

We make a wood disc for an angle grinder ourselves, with our own hands.

The process of forming a new cutting edge is labor-intensive and time-consuming. Therefore, it is recommended to do a number of things in order to increase the service life of the disk.

First of all, you should study the manufacturer's advice. The number of revolutions (highest and lowest) for different types of processed materials is indicated here. For metal this parameter is expected to be less than for wood.

The grinder, or angle grinder (angle grinder), is a very popular tool that is distinguished by its versatility. It is used in most construction work. Many people are interested in the question of whether it is possible to saw a tree with its help. To process this material, you need to choose the right wood disc for the grinder. There are many types of nozzles, differing in characteristics and purpose.

The range of attachments for this tool is quite wide. Products are classified according to purpose, depending on which 3 main groups of wheels for angle grinders can be distinguished:

  • saws;
  • with diamond coating;
  • abrasive.

Saws. They are similar to standard saws, but are made from different materials. The most common option is tungsten carbide discs. They are not suitable for working with wood.

Diamond coated. This group of circles for an angle grinder is the most extensive. The high popularity of diamond-coated nozzles is due to their wide operational range. With the help of such circles you can process metal parts, as well as elements made of stone and concrete. Such disks are not used for wood.

Note! The use of angle grinders requires compliance with certain rules. One of them states that you cannot use circles with a larger diameter than indicated in the device passport.

Abrasive. They are highly versatile. Abrasive discs are used not only for cutting, but also for grinding and polishing surfaces. Products from this group are also used for wood processing.

These products are differentiated by one more characteristic - dimensions. The modern market provides a wide selection of products, the sizes of which vary from 115 to 230 mm. The 115 mm wood grinder blade is the most compact and is used for quick and accurate cutting of material. It is worth noting that the largest discs are not suitable for working with wooden surfaces.

Types of wood discs for angle grinders: design options

Many experts do not recommend using a grinder for cutting and processing wood. This is explained by the operating principle of the device and the characteristics of the material itself. However, the variety of discs for angle grinders is growing every year. They can be divided into several types according to the characteristics of their work.

Circular saws. Such wood wheels for grinders are used, as a rule, for more technologically advanced equipment, but many install them on angle grinders. They are divided into two types: large diameter with soldering and more compact, without soldering.

Chain. Ideal for working with wooden materials. Many people are interested in the question of whether it is possible to cut wood with a grinder. There is no clear answer to this, but chain products are best suited for this purpose. The edge of the circle in this case is equipped with a chain on which the teeth are located. This design has many advantages. This attachment is most often used for smooth cutting of boards. It can also be used to process other materials: chipboard, fiberboard, plywood.

Saws with a small number of teeth. This type of circle was specially invented to ensure maximum human safety when working with wood. Compact products belonging to this group have 3 teeth, and larger ones have 4. This group also includes cutting discs for an angle grinder for wood 125 mm. Such products do an excellent job of their functions. They can be used to cut wood along and across the grain. In addition to standard functions, such disks are used to organize grooves in workpieces.

Segmental (material – tungsten carbide). Such products appeared relatively recently, but have already gained enormous popularity. A distinctive feature of such products is the absence of teeth. The edge of the disc consists of segments that are characterized by high strength.

Helpful information! Using a segment nozzle, you can work with wood of any strength and viscosity. It is highly safe and can withstand even metallic inclusions present in some workpieces (screws, nails, etc.).

Chain saw blades for wood: advantages of use

In this case, the saw blade is made using a chain from a chainsaw. This attachment is the most suitable for working with wood, as it has the greatest efficiency. A chain disk for wood for an angle grinder is also considered the safest. The use of this attachment significantly reduces the likelihood of injury if the tool jams.

If the disk hits a hard element of wood during operation (for example, a knot), the chain is not destroyed. This happens by turning the base. Such attachments are very popular when it is necessary to strip a tree trunk of bark and knots.

Wood saw blades for angle grinders with a chain are used for various types of work. With their help you can remove tree branches, as well as cut boards of small thickness. The functionality of chain products allows them to be used as roughing tools. They do an excellent job of removing bark.

Using a saw wheel, you can make an even cut of parquet boards, plywood, fiberboard, chipboard, as well as ordinary unedged and edged wooden products. It is important to remember that the thickness of the material that will be processed with such a nozzle should be no more than 4 cm. Otherwise, there is a high probability of the device overheating.

Cutting disc for wood for an angle grinder: features

For the manufacture of such products, a special material is used - tungsten carbide. This is explained by the following: when working with an angle grinder, there is a possibility that it will break out of your hands, so the material of the circle must have high strength characteristics. The use of tungsten carbide can significantly increase operational safety, but the cost of such products is quite high.

Discs of this type can have different tooth patterns. A variety of product types based on this feature allows you to choose the most suitable nozzle for a particular situation. The shape and frequency of the teeth also play a very important role. The most common wheel size for working with wood is 125 mm. If you decide to choose the most versatile version of a cutting saw blade for wood for a 125 mm grinder, then it is recommended to purchase a product with beveled teeth.

Helpful information! Wheels that have straight teeth are best for working on soft woods. Coniferous boards are also processed using such attachments.

These products may have teeth that resemble a trapezoid in shape. They are characterized by a wider operational scope and are used for cutting boards of medium density. Using this wheel you can cut the following materials:

  • USB plates;
  • fibreboards.

Wood saw blades for grinders of this type have some design features that are determined by their purpose. For example, during operation, products easily overheat, so they have special slots, which can be empty or filled with copper. This measure allows you to compensate for the thermal expansion of the metal that occurs at high speeds. The width of such slots may vary, but not more than 2 mm. As for their depth, it does not exceed 20 mm.

Wood sanding disc for grinder: characteristics

With the help of a grinder, you can not only cut and saw off wooden parts, but also carry out roughing work of varying degrees of complexity. The modern market offers a wide range of such attachments. They are classified according to several indicators: shape, design and purpose.

Peeling wheels are used to remove bark from logs or boards. Thanks to them, you can easily remove excess wood from the end surface of the board. They may have special spikes or crumbs.

Wood grinding discs for grinders are also used to level the surface of boards. Such circles are equipped with special spikes that are placed on a flat surface. This function is very useful, as it allows you to polish the boards from which the floor covering is constructed.

On sale you can find stripping products consisting of twisted wire. They are usually called brushes. There are two types of such attachments for grinders for woodworking, depending on the features of their structure. The first option provides for a base in the form of a glass to which the wire is attached. The second type is a disk with a wire fixed along the edge.

Brushes are used to remove paint and varnish materials from wooden surfaces. It is important to note that most often such nozzles are used to remove paint and rust from metal pipes.

Note! For wooden parts, it is necessary to choose a thinner wire that will not damage the workpiece itself. These products are suitable for different types of wood.

Wood sanding discs equipped with wire coils are also used for brushing. This event allows you to give the wood an unusual look and artificially age it. However, with the help of an angle grinder equipped with a wire stripping attachment, only small volumes of wood can be processed. Thus, this element is not recommended for brushing on an industrial scale.

Grinding and polishing discs for wood for an angle grinder

Sanding and polishing wood is carried out using special attachments that are used for grinders. Such products include a metal base onto which the grinding wheel is fixed. Fastening is usually done using Velcro.

To use such an attachment on wood for an angle grinder, you need to fix it with a wrench (open-end) on the tool shaft. Quite often it is sold complete with a special adapter element, thanks to which it becomes possible to quickly attach it to a drill chuck. In turn, polishing requires the use of a more gentle material. Therefore, nozzles of this type are equipped with felt discs. They are also secured using Velcro.

Another option for a grinding wheel for an angle grinder is a flap wheel. Its design fully lives up to its name. It consists of a large number of sandpaper petals, closely spaced to each other. If desired, you can select the required paper grain size, which allows you to process wooden materials of varying degrees of density.

Although the grinder is not considered the tool of choice for woodworking, sanding attachments are very common. It is worth noting that grinding in this way is not suitable for smooth surface treatment, since even the most gentle versions of discs for angle grinders leave small scratches on the wood. If you decide to carry out this process as efficiently as possible, then experts recommend purchasing a special device - a grinder. Angle grinders are usually used for materials that will subsequently be painted.

Grinding wheels for grinders on wood: rough grinding

Grinding wheels that are used for angle grinders differ in material of manufacture, shape and operational purpose. The wood processing process itself, as a rule, proceeds in two stages. First of all, rough grinding is carried out, after which the material is subjected to finishing. For rough polishing, several types of attachments are used:

  • peeling;
  • brushes;
  • end circles.

Sanding wood with a grinder using a sanding tool is most often used to remove a layer of old paint. Sometimes nozzles of this type are used to remove varnish coating if it cannot be removed manually. Such circles can have different reliefs, the features of which determine the efficiency with which the product will function.

Brushes are used for sanding different types of wood. Products that belong to this group are classified according to their design, the direction of the wire bundles and their diameter. Depending on their hardness, they are also divided into types. If necessary, it is possible to select the necessary tool corresponding to a particular grinding option.

Helpful information! For rough processing, larger diameter wire is used.

End discs for grinding wood on an angle grinder are used when it is necessary to adjust the size of a part from the end. Often such products are used for regular leveling of the side surface during uneven cuts. The principle of operation of the end attachment resembles the operation of a file. The difference in this case is the high efficiency of the angle grinder.

Using sanding attachments greatly simplifies the processing of wooden workpieces. Such products allow you to restore old furniture by removing paint and varnish compounds from its surface.

Grinding discs for grinders: flap wheels

After rough processing, finishing may be necessary. Of course, if the wood is subsequently painted, there is no need to bring its surface to a perfectly smooth state. However, in most cases finishing is a necessary step. To perform grinding, you can use a common attachment - a flap wheel.

The design of the petal disk model, as mentioned above, includes sheets of sandpaper that have a trapezoidal shape. Their grain size is selected depending on the type of wood and the specifics of the work. This type of wood sanding disc is one of the most common. It ensures gentle processing of the material and has a high degree of safety. It is almost impossible to get injured using this disc.

The efficiency and speed of wood processing, as well as its appearance, depend on the size of the abrasive coating on the petals. For maximum smoothness, it is customary to use fine-grained products. Experts recommend using several of these wood grinding wheels at once. This will make it possible to quickly carry out rough cleaning, and then finish the work with soft petals, bringing the workpiece to the desired degree of smoothness.

The use of such an attachment requires a certain skill from a person. Therefore, before starting to use the petal circle, it is recommended to practice on wooden parts.

Grinding wheel for grinder: soft processing and polishing

To carry out soft grinding, special discs are used, which appeared on the market not so long ago - just a few years ago. Such circles are characterized by a high degree of functionality and can have different grain sizes.

Helpful information! Unlike flap attachments, abrasive particles are fixed with Velcro to the surface of the disc, and not to its end part.

A grinding disc for a wood grinder of this type has one advantage - ease of replacement. This procedure is performed without removing or disassembling the main nozzle, so using such discs is quite convenient. Sticky nozzles can be easily purchased at the construction market or ordered online. Selecting the desired grain size is not a problem in this case. With the help of such devices you can bring the wooden surface to the desired condition.

Polishing, which is carried out after grinding, can be carried out using special felt wheels. Such attachments provide maximum smoothness of the working surface, which is difficult to achieve using other tools. A large number of rotations of the angle grinder promotes uniform polishing of the wood.

Felt discs for grinders include wool (densely compressed), which can have different characteristics (depending on need). On the modern market you can find different types of attachments:

  • fine-haired;
  • semi-coarse-haired;
  • rough-haired.

Attachments for wood processing are characterized by high efficiency and quality. Alternating use of these discs allows you to achieve incredible results. The wood surface after using them can be compared to a mirror.

Safety rules when working with an angle grinder on wood

The use of angle grinders for wood processing requires a serious approach. Incorrect operation of an angle grinder can lead to injury, so before using it, experts advise paying attention to some rules for operating the device. For example, before replacing one attachment with another, you need to disconnect the angle grinder from the network. How to change a disc on an angle grinder? To answer this question, it is necessary to determine the type of circle. Some products are installed without removing the main nozzle. However, in most cases it is necessary to unscrew the flange holding the element.

Note! Under no circumstances should the cover, which is used for protection, be removed from the angle grinder. If the circle breaks, this element will protect your face and other parts of the body from injury from fragments.

Processing wood material using an angle grinder must be carried out with protective gloves. Saw and cutting blades for wood are best used on medium (in terms of power) devices. This can be explained quite simply: if the saw jams, then you still have a high chance of holding the tool in your hands. With a powerful device this will be much more difficult.

For cutting logs and boards, it is recommended to use attachments that have fine teeth. The smaller their dimensions, the less effort required to cut. Among other things, the likelihood of encountering hard wood fibers in the path of the disc is reduced.

Any angle grinder must be equipped with a speed controller, which must be set to the minimum position. When working with cutting tools, it is very important to maintain a right angle. Otherwise, the cutting process will be uneven and the device itself may jam.

An angle grinder can be used for processing wood, but before you start using it, you should study the technical features of the various attachments. Products used for grinding and polishing do not pose any danger and are easy to use. Discs for cutting wood material require careful selection. During work, you must follow safety rules and not deviate from them.
