Wood Cutting Wheel For Angle Grinder
Sawing wood angle grinder
Compliance with the safety rules is the most important rule and an appropriate marked disc for working with wood will ensure your work is perfect. When we cut firewood with an angle grinder, for a safe cut, it is required to fix the angle grinder according to the principle of a circular saw so that the angle grinder does not bounce under our feet. Such work is very unsafe, therefore, if there is an alternative replaced, namely a jigsaw, the same hand tool, or a circular saw, it is better to use them.
Pruning trees with an angle grinder also requires special care and it is worth remembering that small branches with a suitable disc can be sawed off for an aesthetic appearance, but thicker volumes of work should absolutely not be done on wood, especially on weight.
Is it possible to cut wood with a diamond blade?
Diamond discs are used most often for working with granite, tiles and ceramics. For wood, it is better to use discs with teeth. When cutting wood with a diamond blade, the material will smoke and the tool will heat up quickly, which will take time to cool down. Therefore, it is best to use discs as intended for specific materials.

How to cut wood angle grinder
The angle grinder, originally designed for metal working processes, has so many different uses with different types of materials, and even wood is no exception. An angle grinder can be used for woodworking, but you need to be extremely careful and aware of the high risk of hazardous work. When sawing wood with an angle grinder, the surface will not be smooth as, for example, when using a circular saw, but these errors can be easily corrected, the surface can be sanded.
You need to be extremely careful when cutting wood with an angle grinder and a suitable disc designed specifically for sawing wood, but they are not so common on the market. The special disc for working with wood material has teeth that increase the size of the cut. When working on wood, the thickness of the wood should not exceed 4 centimeters.
It is forbidden to work with circles for a circular saw, as the speed of revolutions per minute differs significantly. It is not recommended to use discs with coarse teeth, as there is a high probability of the teeth catching on the material, which will lead to the wheel jamming. The likelihood of snatching the tool out of hand in this situation instantly increases. If possible, set a lower number of revolutions.
The question is often asked: “Can an angle grinder cut wood with a disc for metal?” Of course you can, but not recommended. The wood will simply begin to smoke, an unpleasant odor will appear. It is better to use specially designated discs for this.
In this article, we will show you how to cut wood with an angle grinder.
Plywood cut angle grinder
To cut plywood with an angle grinder, wood discs are often used. Due to the large accumulation of dust, work in a well-ventilated area so as not to breathe burning odors. Sawing is best done along the pre-marked mowing line, pay attention before the end of the process so that the circle does not get jammed by the sawn-off part of the sheet.
Cutting an OSB angle grinder is safer and better with the right blade. The ideal disc would be the so-called three-tooth saw blade for wood, which is designed to work at high speeds. It will be a plus if the angle grinder has a speed controller.

Types of woodworking attachments for angle grinders
When we talk about woodworking, we mainly mean sanding the surface. And this procedure is carried out in 2 stages. rough cleaning and finishing. The first one allows you to eliminate various defects, irregularities, the last one. to achieve a perfectly smooth surface. But in order for the processing to be as efficient as possible, you should choose the right type of consumable.
A roughing wheel is used to remove bark from wood, eliminate irregularities and trim the log. In addition, with the help of such a disk, it will turn out to make cutting and sawing of the material.
Cord brushes are also used for rough processing. The working surface of such nozzles is covered with coarse abrasive, due to which they do an excellent job of leveling the surface, as a result of which the wooden blank gradually acquires the desired features. But the purpose of the end discs is to process slices. The use of consumables of this type is especially relevant when it comes to corner cuts.

The final cleaning of wooden elements is carried out using grinding and polishing wheels. Such consumables are classified according to the type of coating and grain size, depending on which the cleanliness of the grinding differs. The circle itself is attached to a special metal nozzle. As it wears out, the consumable simply changes to a new one. Grinding discs have found their use when carrying out coarser processing. For polishing, special brushes made of felt and sponge are used, as well as discs with a fine-grained structure.
Flap discs for angle grinder are among the most popular. They have an unusual design. “petals” made of trapezoidal sandpaper are overlapped. This contributes to a longer consumable life. Also, their advantages include the minimum risk of injury. And a variety of flap wheels of different grain size allows you to choose a nozzle depending on the type of processing.
There are also special cutters. Their area of use is leveling edges, making grooves, cutting out a bowl and sawing small sections of wood. The design feature is the presence of a tooth. over, depending on the type of cutter, the tooth may differ in size, location and configuration.
Choosing an angle grinder attachment for wood processing
Features of choice
In order for the work to be as effective as possible and give the desired result, it is necessary to choose the right consumable. There are a number of factors to consider when choosing an attachment for an angle grinder or angle grinder:
- outer diameter of the disc. On the one hand, the larger the size of the circle, the faster the work will take place, but on the other hand, the diameter of the disc must correspond to the characteristics of the tool;
- bore diameter;
- grain. Coarse-grained consumables are intended for rough surface treatment, and fine-grained ones for finishing;
- thickness. This parameter affects the service life. Thicker discs last longer;
- segment type.
Be sure to take into account all the factors and only then can you count on productive work and results!
Useful tips for use
Choosing the right attachment for your grinder is important, but safety is just as important. And for this it is necessary to strictly adhere to certain rules during work. Use the attachment only for its intended purpose, do not cut wood with an angle grinder with circular saw blades. This is very dangerous and can lead to serious consequences, for example, if a nail, metal clip or even a knot is caught in a wooden blade, the saw blade tooth can break off and injure you.
Also, do not use the wrong size consumables. It is strictly forbidden to use consumables with a larger diameter. in this case, you will have to violate safety measures and remove the protective cover. And the power of the tool may not be enough, and this will lead to its overheating and failure. Install the accessory only on a de-energized angle grinder. And do not forget to use all necessary personal protective equipment during work. Durable gloves keep your hands free and your glasses keep dust and wood chips out of your eyes. And when cutting a wooden blade, observe the perpendicular, because changing the angle of inclination between the surface and the working tool can lead to the destruction of the latter.
It is best to work at low rpms, this will prevent the tool from being pulled out of your hands if jamming occurs. But constant changes in the operating mode lead to overheating of the engine, which significantly reduces the service life of the tool.

The reverse side of the disc
The Yato disc has good cutting properties. First, there are 28 carbide teeth located around the circumference, leaving a clean cut and fine chips. Secondly, there are notches on the side of the disc, which during the cut work like cutters and grind the side surfaces. Therefore, such a disc is sometimes called a wood cutter.
Feature of Yato YT-59172:
- Outer diameter of the disc. 125 mm.
- Bore diameter. 22.2 mm.
- Rotation speed. 13000 rpm.
- Number of teeth: 28 pieces.
- Case thickness: 3mm.
- Cutting width: 5 mm.
- Processed materials: wood, chipboard, plywood, drywall, lightweight porous aerated concrete, plastic.
- Considered safest when installed on an angle grinder.
Proline disc characteristics:
Such cutting discs can be used for cutting boards with a thickness of no more than 40 mm, in compliance with all safety measures.
The saw blade has a metal base and a chainsaw chain fixed around the perimeter
- It is strictly forbidden to remove the protective cover if the disc diameter exceeds the dimensions of the casing. your angle grinder cannot be used.
- The angle grinder must be running at the rpm indicated on the disc. Otherwise, the chain may jump off and scatter its components.
- Safety glasses and heavy gloves are required. It also does not hurt to wear thick canvas clothes.
The same applies to diamond cutting discs for concrete. They are unsuitable and dangerous for sawing wood products. First, the operating efficiency is extremely low, especially considering the cost of the disk. Secondly, you can simply burn through the workpiece.
And finally. such a disc at any time can jam in the cut, and you will get hit by the body of the angle grinder. Here is an example of an angle grinder blade that can be used to cut wood with extreme care.
The design of the wheel provides protection against seizure by means of side teeth that widen the kerf. The disc has a diameter of 115 mm, and its dimensions allow you to work without removing the protective casing.
The wood disc fits completely under the protective cover
Some homebrew “craftsmen” fit standard circular saw blades to an angle grinder, work is done with the protective cover removed. Most often, such experiments end tragically. The grief-master is seriously injured, and death is possible.
At the same time, the construction markets are full of proposals for saws for an angle grinder for wood. Sellers will assure you that in the hands of a professional, using such a tool is completely safe. This statement is true as long as these very hands are safe and sound.
Reasons why you cannot use a circular disc when working with an angle grinder:
- The disc is designed for low speed, the metal of the circle is hard, but brittle. During operation, it can fly into pieces or soldered teeth can fall off from the disk, which fly off at the speed of a bullet;
- The wood has a viscous structure, so the teeth bite unevenly. Due to this, the instrument bounces and vibrates. It is easy to lose control of the instrument and seriously injure yourself;
- If the disc is jammed (and when working with wood, this situation will surely arise), the angle grinder will simply rip out of your hands. The further behavior of the switched on tool with a rotating toothed disk is unpredictable;
- During woodworking due to uneven loads, the angle grinder overheats and may fail.
The only way out is to make a stationary sawing machine, with a securely fixed angle grinder, as the master did in the video tutorial.
It makes no sense to consider the option of cutting wood blanks using abrasive wheels, since such a disk will not work effectively anyway. This is tantamount to trying to cut a log with a file. True, the safety will be at a high level.
Accessories for various types of wood sanding
Application of the angle grinder as a planer
When roughing logs, for example, for the construction of a log house, special planer discs are used. This is a relatively safe way of processing wood, subject to the rules of operation. It is a mechanized replacement for the carpenter’s ax.
Arbortech TURBOPlane disk planer. The disc can be sharpened many times
The nozzle is used without a protective cover, since its destruction during operation is excluded. It is forbidden to use such a disk by turning it up. When working on an angle grinder, a handle must be installed to hold the tool with both hands.
Since when stripping a tree, large chips fly out of the working area. you need to have tight overalls and protect not only the eyes, but also the face.A positive side effect of this tool is that you can easily chop up shavings and large sawdust for a home smokehouse.

A power tool familiar to work with metal, an angle grinder is effectively used for processing other materials. Many people put a disc on wood on an angle grinder without thinking about safety.
Is it possible to saw wood with such a disc and what types of auxiliary tools for an angle grinder are, let’s figure it out.
There are special cutting discs for wood designed for such work, but this is rather an exception. In addition, such a disc is not suitable for every angle grinder.
Consider several options.
Flap sanding attachments
The most common segment of attachments for angle grinders. They are used for processing any materials, including wood.
Depending on the size of the abrasive, either quickly remove an uneven layer, leaving the surface rough, or smooth out all irregularities without removing a large thickness.
Correct use is a consistent transition from coarse grain to finer processing. Thanks to the rigid base, they allow you to apply a lot of pressure on the workpiece to increase efficiency.
Structurally, they consist of trapezoidal sandpaper petals, overlapped with an overlap of three quarters. Due to this, when erasing the edges, the next layer works.
Nozzle wear is quite slow. A petal nozzle with a radial arrangement of sandpaper strips is intended for cleaning wooden products of complex relief shapes.
The tool requires certain skills. In case of careless handling, it is easy to “chuck” the protruding parts of the workpiece. Before using it is recommended to practice on unnecessary pieces of wood.
Radial abrasive scraper disc
To remove the bark from the logs, and give them the shape of the primary workpiece. there are special roughing attachments for the angle grinder.
Example of a peeling attachment using a chainsaw chain
With the help of such a chain wheel, you can not only clean the trunk from bark and branches, but also give the workpiece the required shape for subsequent processing with a more accurate tool. Such a device can easily replace an ax for cutting a bowl in a log during the construction of wooden log cabins.
You can use this disc as a cutting disc, but the cut will turn out to be torn and the loss of wood is too high, the thickness of the cut is several centimeters.
Milling with an angle grinder
Another dangerous tool, but allowed for use, subject to precautions, is a wood cutter for an angle grinder.
The setting diameter of the cutter for wood is suitable for the bore diameter of the angle grinder
With the help of such a cutter, you can make grooves, roughly level the edge, cut out bowls for a log house, and even cut workpieces. Design eliminates jamming and knocking of the tool on uneven wood.
Before use, be sure to read the instructions, especially the sections on maximum revolutions and direction of rotation in relation to the position of the angle grinder.
The range of milling cutters for an angle grinder is not inferior to the choice of attachments for a hand mill. Of course, you will not achieve the same exact processing, but you can choose a suitable nozzle to give the workpiece any shape.
Disc for high tooth angle grinder
After giving the workpiece the required shape, you can proceed to finishing, final processing. Let’s remember the correct name “angle grinder”. angle grinder.
Despite the fact that most often the angle grinder is used as a cutter, its main purpose is grinding and polishing. And for woodworking in this capacity, the angle grinder is an indispensable tool.
Review of for popular models
The cost of products depends on the place of their sale, technical characteristics and manufacturer’s brand. In this section of the article, several models are presented, on the basis of which you can get an idea of the order of the numbers that determine the cost of a particular type of similar products.
Features of application of the angle grinder for wood
Sawing wood with a hand tool comes with a number of features. Wood is a heterogeneous natural material, its density is unevenly distributed. After a relatively loose area, a denser area may suddenly begin, there may be defects hidden in the thickness, once filled with resin during the growth of the tree. There may be developed or underdeveloped knots, and sometimes ingrown foreign inclusions (nails, wire, shot, or even bullets that fell into a tree in the forest, for example, during a hunt).
Thus, it is almost impossible to unambiguously select the operating mode of the cutting hand tool. This can lead to jerks, the energy of which will have to be extinguished with the help of the hands; in special cases, the instrument may even break out. If a cutting tooth hits the metal, it can be broken and ejected by the next tooth at a sufficient speed to cause serious injury.
Unlike circular saws (stationary or mobile), an angle grinder has a greater number of revolutions on the pulley, this is necessary to perform its main function. grinding.
When adjusting this tool for sawing wood, the craftsmen often removed the protective cover, which is categorically unacceptable, given the above-mentioned features of wood, as a natural material with unpredictable variations in properties. If the need to use an angle grinder as a circular saw still arises in order to ensure safety and get the greatest effect, you need to purchase a special disc designed specifically for this tool.
The GRAFF Speedcutter is a low tooth count model
The blade is intended for sawing wood and plywood, laminate and board materials (fiberboard, chipboard). The model is equipped with three teeth.

General characteristics of discs for “angle grinder” depending on the type
Discs designed for different types of use differ in their design and materials used in their manufacture. In this regard, for different types of similar products, the general characteristics differ, which requires their separate consideration.
Circular disc for angle grinder for wood, 125 mm
Saw blades for angle grinder
Saw blades for wood for an angle grinder have been developed by various manufacturers and, accordingly, have several varieties. The simplest and definitely the most budgetary option is to install a circular disc of appropriate dimensions on an angle grinder. both the outer diameter and the diameter of the inner mounting hole. For an angle grinder, which according to its dimensional characteristics is classified as a small one, a 125×22 mm circle is suitable.
Technically, a disc with a diameter of 230 mm can be installed on a small angle grinder, but for this you have to remove the protective cover, which is absolutely unacceptable. The user’s hands of the angle grinder are in close proximity to the rotating work surfaces and any abnormal situation can cause serious injury. Using such a wheel on an angle grinder can cause serious safety violations and is strongly discouraged for beginners.
Any misalignment, including those associated with the unevenness of the wood structure, can cause the disc to jam and, as a result, a sharp jump of the entire unit, up to the point that it can escape from the hands and make a dangerous unpredictable flight. The circular saw blade is not designed for such fast revolutions as the spindle of an angle grinder produces; this results in its excessive heating, which affects the strength of the steel. As a result, when skewed, the saw wheel may collapse with the scattering of fragments at high speed in unpredictable directions.
Special attachments for sawing wood, developed for UMSH, have significant differences from the circular saw blade. Let’s consider the most common options for sawing wood. On sale you can find saw blades similar to circular saws, which have an increased set of teeth, which significantly reduces the likelihood of their jamming. In addition, the differences for the manufacture of such a disk are that other alloys are used, this reduces the risk of destruction of the disk when it is heated.
Further attempts to protect the blade from jamming led to the combination of circular and chain saws in one product. A chain similar to a chainsaw chain moves freely along the working surface of the disc, which absolutely excludes jamming. There are quite a few modifications of such a hybrid. Craftsmen with the help of such a combination saw successfully saw branches and can even saw not very thick trees.
Another trend in adapting circular saws for use on an angle grinder is to reduce the number of teeth. The discs with a diameter of 115 mm or 125 mm have only three teeth, the disc for a large 230 mm angle grinder can have 4 teeth. In this way, manufacturers tried to compensate for the high rotation speed of the saw blade.
A completely new direction in the evolution of circular discs was marked by the invention of a special nozzle that is suitable for working on various materials. This universal disc is made of a special composition. tungsten carbide. There are no teeth at all on such a saw blade. This type of disc allows you to cut a wide variety of materials well, it can be considered the safest disc for sawing wood of all that is used on an angle grinder.
Standard disc sizes for “angle grinder
In the production of discs for angle grinders, companies operating in our country produce their products in accordance with the following regulatory documents:
- GOST 21963-2002 (ISO 603-15-99, ISO 603-16-99) “Cutting wheels. Technical conditions “.
- GOST R 53410-2009 (ISO 603-12: 1999-ISO 603-14: 1999, ISO 15635: 2001, ISO 13942: 2000) “Grinding wheels for hand-held grinding machines. Technical conditions “.
According to these documents, the standard disc sizes used on an angle grinder are 115, 125, 150, 180 and 230 mm.
For your information! Landing dimension for all standard sizes is 22.2 mm.
The use of an angle grinder for grinding wood products is quite widespread among users of different categories.
It is necessary to follow the rule: the larger the rasp disc, the lower the speed. In addition, manufacturers protect the user as much as possible by releasing discs with high (sometimes double) strength. But if you use more disk than is necessary, all these measures become meaningless.
Important tips on what to do:
- work with a protective cover;
- protect the face and head;
- check lumber for nails and screws;
- hold the device firmly by hand;
- use an additional handle (many hold the device with one hand);
- do not allow the tool to heat up, avoiding the risk of smoke.
In addition, if there are no plans for large-scale work with an angle grinder, you do not need to buy many discs “in reserve”. since the moisture contained in the air begins to affect Bakelite. The bond strength is noticeably reduced. Better to get the right wood discs for your angle grinder (angle grinder) right before you start working.

Even a schoolboy knows what an “angle grinder” is nowadays. it is an angle grinder designed to work with metal workpieces by using special cutting and grinding wheels. Not everyone knows that such an electric tool can be used for wood processing, but only professionals, so this article is intended to fill this gap in the information available to ordinary users. Disc for an angle grinder for wood. types, general characteristics and standard sizes, as well as safety measures for use and an overview of for popular models. this is the topic of this article by the HomeMyHome.ru editorial office
Depending on the type of discs used, the “angle grinder” in skillful hands can be used at various stages of working with wood blanks: from sawing to grinding.
And whether it is worth using an angle grinder in this way, each user decides purely individually, weighing all the pros and cons for each type of discs sold by trade enterprises.
Save time: select articles by mail every week
an angle grinder, or an angle grinder, is a tool that has no analogues in its popularity. If initially the scope of its application was limited to operations that determined the name of the unit (grinding and technologically similar types of material processing), then gradually the range of application of this power tool and the replaceable nozzles produced for it has incredibly expanded. Now the angle grinder cuts metal, grinds various surfaces, removes dirt and old paint and much more.
The presence of a rotating rod made it possible to adapt the angle grinder for sawing wood. They began to try to install saw blades produced for circular saws on it. Manufacturers of attachments for this tool have responded by developing and producing special wheels, similar in effect to circular saw blades, but adapted to high speeds and increased safety requirements for hand tools.
Tungsten Carbide Discs
Tungsten carbide discs for angle grinders were recently launched and revolutionized woodworking.
This universal disc has no teeth. Instead of the latter, segments are located around the circumference of the nozzle. The trimming disc is similar in appearance to a diamond wheel for cutting concrete. With the tungsten carbide wheel for angle grinders, you can cut wood of any hardness and toughness very easily. 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 we take into account the possible consequences of using circular saws, then this is a low price for safety.
The saw blade, made using a chainsaw chain, reduces the risk of injury when the tool is jammed. This attachment is designed in such a way that the chain attached to the inner disc (base) has a non-fixed fit.
In the event of a chain jam in the material being processed, the base continues to rotate and the tool does not pull out of the hand.
This angle grinder chain disc has many modifications, and can be used to cut branches in the garden, and can also be used for rough cutting of thin boards.
In addition to cutting, the chain disc can also be used as a roughing disc, for example, for removing bark, as well as for cutting out cups in logs and modeling.
Grinding and polishing attachments
For sanding various surfaces, including wooden ones, there is a special attachment for an angle grinder on sale, consisting of a metal base, on which an emery grinding wheel is fixed with Velcro. The attachment is screwed onto the shaft of the angle grinder and tightened with an open-end wrench.
Often it is equipped with an adapter for fixing a drill or drilling machine in the chuck.
The grinding wheel is not used for polishing surfaces. Instead of it, felt discs are installed on the nozzle, which are attached with Velcro.
Also, a flap emery wheel is often used for sanding wood surfaces. It is called from so because it consists of many petals fixed on its plane, made of sandpaper. The granularity of the latter can be selected based on the requirements for the treated surface. Emery with a coarse grain is suitable for rough grinding, and vice versa for finishing.
What is the best way to sand wood. an angle grinder or a sander. depends on what you are going to prepare the wood surface for. If for applying ordinary paint, then you can use a grinding wheel. If for varnishing, then the grinding wheel mounted on an angle grinder cannot be used, since it will give small radial scratches on the surface of the wood, which will clearly appear after applying the varnish. In this case, a longitudinal belt sander is used for grinding (the emery belt moves longitudinally) or vibration, where the same emery wheels are used.
Planar blade disc
A disc with several laterally protruding blades can be considered an alternative to a plane. It is intended primarily for flat material removal. This attachment is indispensable for logging, allows you to quickly and efficiently remove bark from unedged boards or logs. It is also convenient to handle convex or form concave surfaces.
It is very difficult and time-consuming to do such work with a plane. In addition to the obvious usefulness, the disc made of high-quality steel has a good resource. And dull blades can be sharpened without the use of special tools.
What are the circles for cutting wood
Despite the dangers of using an angle grinder for cutting wood, tool manufacturers still produce saw blades for it.
Wood grinding attachments
For wood processing, in addition to cutting wheels, there are attachments specially designed for installation on an angle grinder, with which you can peel, grind, brush and milling wood surfaces.
Saws with few teeth
Also for the angle grinder, in order to increase the safety of working with wood, tool manufacturers produce cutting discs with a small number of teeth.
Small diameter discs can have 3 teeth, and large ones. 4, as shown in the following photo.
These discs for angle grinders are excellent for cutting wood both along the grain and across. In addition, with the help of a saw wheel, you can cut grooves, make various cuts and spikes in the workpiece. But when working with an angle grinder, one rule should be followed: you need to install a cutting disc of the same diameter on the angle grinder, for which it is designed by the manufacturer, that is, do not exceed its dimensions. Smaller circles can be used.
