An angle grinder, if you know and correctly use all its capabilities, is a truly universal device that lends itself to almost any material. And if we are talking about processing wood on a large scale, then the “grinder” is much more effective than manual abrasive tools and fixtures. The main thing is to choose the right nozzle. This article will help you understand their main modifications and specifics of application.
Rough cleaning of wood
planer disk
Such a nozzle almost completely replaces this hand tool.
An irreplaceable thing, if it is required, for example, to make a rough processing of a log - when erecting a log house, preparing fence supports, and so on.
Application Features:
- AT this case the protective cover can be removed. Such a nozzle is one-piece, and its destruction does not occur. But protection from flying wood chips (glasses, tight clothing, gloves) is required.
- It is allowed to work only with a “grinder”, in which a second handle is provided (or installed). The angle grinder must be held when roughing wood with both hands.
Peeling disc
The main purpose of such nozzles is to remove the bark from the wood, to trim the workpiece. If the "grinder" is in capable hands, then with such a device you can make a sample of the material. For example, if you need to cut a bowl. If erected log house, then an angle grinder with such a nozzle perfectly replaces a carpenter's ax.
In some cases peeling disc cutting can be done. True, the cut will be wide, and there will be a lot of waste (chips, sawdust).
Milling
Disks
These nozzles are available in various designs. The main difference between the devices is the size of the abrasive grains.
They are not much different from rasps in terms of specific application. The difference is only in the speed of execution technological operation. With certain skills, it is advisable to use these for finishing wood.
cutters
They are, and specially for wood. The assortment is significant, since nozzles of this type differ in the configuration, location and size of the teeth.
Purpose of cutters:
- Selection of grooves.
- Edge trimming.
- Cup cutout.
- Sawing (for wooden blanks of small section).
Application specifics:
- When processing wood with such nozzles, it is forbidden to dismantle the protective cover.
- Each product has instructions. It clearly indicates for what types of work this nozzle is intended, the recommended speed of the grinder, and so on.
wood sanding
If you decipher the abbreviation angle grinder, then it is clear that it is the finishing that is the main purpose of the grinder.
cord brushes
They are mainly used for primary (rough) grinding of wood, when it is required to smooth out the irregularities of the sample.
End disks
The names speak for themselves. Such nozzles process the final parts of wooden blanks (cuts). Especially effective if you have to deal with angular (oblique) cuts.
Petal nozzles
The most used grinding devices for the grinder.
Such nozzles are applied sequentially, so several of them will be needed to process wood. Grinding begins with a disc with a "coarse" abrasive, and gradually the size of its grain must be reduced. Consequently, the devices in the process of working on the "grinder" periodically change.
grinding wheels
The most universal adaptation to the "Bulgarian". It alone is enough for varying degrees of grinding. The nozzle itself is a metal base on which circles with one grain or another are attached. They are easy to change, or as they wear out, or in the event of a transition to another area of work. Therefore, only circles are consumables. The nozzle itself is used indefinitely.
Application specifics:
- Wood grinding.
- Parquet scraping.
- Edge and end processing.
- Cleaning wood before painting.
wood polishing
For these purposes, brushes, disks, circles are used. Their "working elements" can be made of sponge, felt, fine-grained "sandpaper" and a number of other materials.
The article provides examples of only the main types of nozzles for the grinder. There are a lot of products of this class, so it's easy to choose best option devices for processing any wood. The author hopes that the information provided will help the reader in this.
On a note!
Wood processing also means its cutting (sawing). Sometimes, in the manufacture of piece parts, it is necessary to adjust them at the installation site even before starting to grind the sample. Some "craftsmen" (and there are many of them among friends and on the Internet) are advised to use for such operations. It is strictly forbidden! Here are just the main reasons why this should not be done.
- "Bulgarian" - a high-speed machine. And although the metal from which they are made cutting discs, durable, in this mode it does not withstand for a long time. More precisely, cutting edges(teeth), which are fixed by soldering. With intensive work, they fall off and scatter to the sides, and with great speed. The consequences are easy to predict.
- Not all discs are suitable for installation on angle grinders in terms of size (primarily, outer diameter). So, you have to dismantle the protective cover. The same thing - you can forget about the safety of the employee.
- The structure of wood (even hardwood) is quite loose. Therefore, it is highly likely that the saw blade may jam due to constant vibration. How the “Bulgarian” will behave in such a situation, given its power and speed, no one will undertake to predict. But the fact that it breaks out of hands quite easily is unequivocal.
- Constant changes in the mode (for the same reason - the viscosity of the lumber) lead to a systematic overheating of the angle grinder engine. With this use, the "grinder" will not serve for a long time.
That is why wood processing with its help is carried out only superficially - rough sweep, grinding, brushing. And for cutting, you should use sawing tools and mechanisms (hacksaw, circular saw, electric / jigsaw, and so on).

What is a “grinder” at the present time, even a schoolboy knows, is an angle grinder designed to work with metal blanks by using special cutting and grinding wheels. The fact that such an electric tool can be used for woodworking is not known to everyone, but only to professionals, so this article is intended to fill this gap in the information available to ordinary users. Disc for a grinder on wood - types, General characteristics and standard sizes, as well as safety measures for use and an overview of prices for popular models- this is the topic of this article of the editorial site
Depending on the type of disks used, the "grinder" in skillful hands can be used on various stages work with wooden blanks: from sawing to grinding
"Bulgarian" was not originally intended for sawing wood, especially for workpieces of considerable thickness and wood hard rock. This is due design features this type of tool and associated with such dangers of use:
- when jammed saw blade it is difficult to hold the angle grinder in the hands, which can lead to injury;
Important! Jamming of the saw blade when using a "grinder" for sawing wooden blanks is the most common problem in this type of work, which is due to the softness and viscosity of the wood.
- uneven wood structure due to knots can damage the saw blade being used and injure the user.
Despite the potential danger use of angle grinders as a tool for sawing wood products, manufacturers Supplies, which include discs for the "Bulgarian", produce similar products.

Ask a Question“For processing workpieces of considerable thickness and with professional use it is most correct to use a tool originally intended for sawing wood, which are a circular saw and a circular saw.
The main and most common uses of the "grinder" when working with wood are: its peeling, grinding and polishing, for which manufacturers produce special types disks.
General characteristics of discs for "grinder" depending on the type
Discs designed for different types use, differ in their design and materials used in their manufacture. In connection with this, different types similar products, the general characteristics vary, which requires their separate consideration.
Cutting models
- circular– considered “dangerous” saw blades;
- chain- are made using links designed for chain saws;
- with few teeth- are the safest, compared with circular analogues;
- tungsten carbide- the safest type of such equipment.
Note! Circular discs come in two modifications: this is a "dangerous" and "less dangerous" option. Distinctive feature models of the "less dangerous" type is the presence of anti-jamming provided by the setting of the teeth.
Chain modifications are less dangerous when used, as they their design provides for a non-fixed fit saw chain on the surface of the disk.

Ask a Question“When the saw chain is jammed during its use, the disk attached to the angle grinder continues to rotate, the tool does not break out of the hands, allowing it to be emergency stopped.”
Discs with a small number of teeth are of two types:
- with 3 teeth- used with small "grinders" with a diameter of up to 150 mm;
- with 4 teeth- are used on "grinders" of a large size with a diameter of 230 mm.
A distinctive feature of models made of tungsten carbide is the absence of teeth on the cutting surface of the product. Segments located along the circumference of the disc act as a cutting element.
Important! Tungsten carbide models are able to cut various hardware(nails, self-tapping screws, etc.), which can be in the workpiece without damaging the cutting elements and their integrity.
Grinding discs
For peeling wooden products, manufacturers produce several types of nozzles that differ in design and types of materials used in their manufacture.
By design, such nozzles can be made in the form of:
- a disk with spikes or crumbs applied to its surface;
- a glass with cutting elements made of twisted wire inserted along its circumference;
- disk with wire coils mounted on its surface.

Ask a Question“Scraping attachments are used to remove paint and other coatings applied to a wood surface, as well as to roughen a leveled wood surface.”
Models for grinding and polishing
To perform grinding and polishing, there are special nozzles used both for wood and for other materials (metal, plastic, glass, etc.).
Nozzles used for such purposes are of two types:
- the basis of the design is a metal base, fixed on the angle grinder shaft, and circles made of sandpaper of different grain sizes or polishing materials (felt, cloth, etc.), which, in turn, are attached to the base with Velcro;
- petal emery wheel.
Standard disc sizes for "Bulgarian"
In the production of discs for angle grinders, manufacturers operating in our country produce their products in accordance with the following regulatory documents:

Safety measures when working with a grinder on wood
When performing work on wood processing using an angle grinder, the safety measures are the same as in cases of using metal and other materials. However, in connection with physical properties trees, which have already been written about above (softness and viscosity), it is necessary to take them into account, and in this regard:

Angle grinder - very useful tool, which can be used in various fields of production. It is due to its versatility that it has become widespread both at industrial facilities and at the household level.
Types of nozzles for wood
As a tool for woodcarving, only angle grinders with speed control are suitable. Since the main purpose of the grinder is the grinding of homogeneous materials, then to the processing of an inhomogeneous structure wooden materials must be approached very carefully.
The following types of circles for wood can be distinguished:
- Wood saw for grinder
- Cutting discs
- planers
- Grinding
Each of these parts must be used for its intended purpose.
saw blades
A saw blade for wood for a grinder consists of a metal circle with a chain attached to the edge. Design of special saw tools similar to those used on chainsaws. But saw blades are made of tungsten carbide. When a disk for a grinder on a tree hits a solid obstacle in the wood - knots, resin, metal, its base rotates without breaking the chain. With chain nozzles, it is quite easy to clean the logs from knots and bark, to give them the necessary initial shape.
Cutting discs
Various manufacturers produce and cutting wheels on wood specifically for angle grinders, for example, a Bosch cutting wheel. Their design differs significantly from the design of disks for circular saw. Usually they have side teeth that protect the nozzle from jamming. Differ cutting tools by number and shape of teeth:
- bevelled;
- straight;
- in the form of a trapezoid.
The first version of the shape of the teeth is considered universal. It is suitable for all types of wood with small amounts of work. When sawing wood from soft varieties, it is quite possible to use discs for a grinder on wood with a straight tooth. Trapezoidal teeth are capable of processing quite solid products from wood: chipboard, fiberboard, OSB boards.
In addition, cut-off wheels vary in diameter. Minimum size- 115x22 mm. The most commonly used circles with a diameter of 125 mm, they are universal and suitable for a wide range of jobs. Maximum possible size- 230 mm. But the latter option is undesirable to use when working with wood, as the likelihood of injury increases. Depending on the size chosen, the depth of cut in the wood will also be different.
Disks - planers for grinders
It is possible to use the angle grinder as a planer. For this, special circles are used - planers. Work with such nozzles is allowed without a protective casing, since solid discs are not destroyed. Many brands of wheels can be sharpened repeatedly. Before use, an additional handle must be installed on the angle grinder to more securely hold the tool with both hands.
Grinding discs
This type of circles allows you to use the machine for its intended purpose. For finishing and polishing wooden surfaces can be used different kinds nozzles:
- cord brushes;
- end circles;
- petal nozzles;
- emery circles;
- cutting nozzles.
Rough processing of wood is carried out with the help of special cord brushes. end discs are designed to align the edges of parts, which is often required for oblique cuts of workpieces. They make a great file replacement.
The widest range sanding attachments- at petal circles. Depending on the size of the abrasive grain, the wood surface can be cleaned with varying degrees grinding. With a gradual transition from using a coarse-grained nozzle to discs with finer grains, the effect of polishing parts is achieved. The system of trapezoidal petals, which are stacked with a three-quarter overlap on each other, wears rather slowly. If the embossed surface wooden product complex, then used petal discs with a radial arrangement of abrasive strips.
Using sandpaper or sandpaper on a special nozzle allows you to grind quite large areas wooden surfaces. The ability to quickly change the sanding cover makes these tips versatile.
When deleting old coatings often use peeling nozzles. Typically, this is a wire brush attached to metal base. It can be located either parallel to the surface of the circle or perpendicular to it. There are options for fixing the bristles on the perimeter of the disc.
When working with wood, you need to make sure that it is fairly dry. If there is fungal damage on the surface of the workpiece, they must be cleaned to healthy wood.
Universal wood discs for grinder Graff Speedcutter
The Graff Speedcutter wood saw blade is a three-tooth saw blade designed for high-speed angle grinders. It is used in models with a maximum rotation speed of 12.2 thousand revolutions per minute.
The three carbide teeth are made of tungsten carbide and set at a 5° angle to the steel base of the tool. Thanks to this design and the special shape of each tooth, the cut surface is very clean and even. A disc is being made for the Graff Speedcutter grinder with a size of 125x22.23x3 mm. The cutting width of the wood is 3.8 mm.
Designed Graff Speedcutter circles for artistic wood carving, cleaning and grinding various breeds tree. They are also used when cutting and selecting grooves in wood, its transverse cutting and longitudinal cutting. It is possible to use such nozzles when processing parts made of aerated concrete and gas silicate, fiberboard, chipboard, laminate, drywall.
Rules for working with the tool
Any tool can be a serious hazard if the instructions for use are not followed. specific situation. Bulgarian for cutting wood in this sense is no exception. The main points that are necessary when working with disks for an angle grinder - angle grinder on wood:
- Choosing the right circle size
- Installing a wood disk for a grinder
- Selecting the appropriate operating mode for the machine
- Refusal to use damaged circles
- Use of personal protective equipment
The nozzle size should be installed without problems under the protective cover of the machine. If this does not work, do not remove the protection. When working on wood with an angle grinder, it is necessary to use only special circles on wood for an angle grinder. The use of attachments that are designed to work on other materials may result in injury or a damaged tool. In order to avoid the destruction of the disk on wood for the grinder, revolutions grinder must match those indicated on the surface of the circle. Before starting work, it is worth checking the wood disk for defects and damage. If they are present, then it becomes dangerous to use. When working with the tool, eye and hand protection must be used. It would be best to use tight overalls.
The grinder, or angle grinder, is a tool that has no analogues in its popularity. If initially the scope of its application was limited to the operations that determined the name of the unit (grinding and technologically related types of material processing), then gradually the range of application of this power tool and the replaceable nozzles produced for it expanded incredibly. Now the grinder is cutting metal, grinding various surfaces, cleaned of dirt and old paint and much more.
The presence of a rotating rod made it possible to adapt the grinder for sawing wood. They began to try to install saw blades manufactured for circular saws on it. Manufacturers of bits for this tool have responded by developing and producing special wheels, similar in action to circular saw blades, but adapted to high speeds and increased safety requirements. hand tool.
Features of the use of grinders on wood
Sawing wood with a hand tool is associated with a number of features. Wood is a heterogeneous natural material, its density is unevenly distributed. After a relatively loose area, a denser one may suddenly begin, there may be defects hidden in the thickness, filled sometime, in the process of tree growth, with resin. There may be developed or underdeveloped knots, and sometimes ingrown foreign inclusions (nails, wire, shot or even bullets that hit the tree while still in the forest, for example, during hunting).
Thus, it is almost impossible to unambiguously choose the mode of operation of a cutting hand tool. This can lead to jerks, the energy of which will have to be extinguished with the help of hands, in special occasions the instrument may even break free. If a cutting tooth hits metal, it can be broken and ejected by the next tooth with enough speed to cause serious injury.
Unlike circular saws (stationary or mobile), the grinder has a higher number of revolutions on the pulley, this is necessary to perform its main function - grinding.
When adapting this tool for sawing wood, the craftsmen often removed the protective cover, which is categorically unacceptable, given the above features of wood, such as natural material with unpredictable properties. If the need to use the grinder as a circular saw nevertheless arose, in order to ensure safety and get the greatest effect, you need to purchase a special disc designed specifically for this tool.
Saw blades for angle grinders
Wood saw blades for angle grinders were developed by various manufacturers and, accordingly, have several varieties. The simplest and definitely the most a budget option- install on the grinder a disk for a circular of appropriate sizes - both the outer diameter and the diameter of the inner mounting hole. For a grinder, which, according to its dimensional characteristics, is classified as small, a circle of 125x22 mm in size is suitable.
Technically, a disk with a diameter of 230 mm can also be installed on a small angle grinder, but for this you will have to remove the protective cover, which is absolutely unacceptable. An angle grinder user's hands are in close proximity to the rotating work surfaces and any abnormal situation can cause serious injury. The use of such a circle on an angle grinder can cause serious safety violations and is strongly discouraged for beginners.
Any misalignment, including those associated with the uneven structure of the wood, can cause the disc to jam and, as a result, a sharp jump in the entire unit 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 that the grinder spindle gives out, this results in its excessive heating, which affects the strength of the steel. As a result, damage can occur when skewed. saw blade with fragments flying at high speed in unpredictable directions.
Special attachments for sawing wood, designed for UMSh, have significant differences from the circular saw blade. Consider the most common nozzle options for sawing wood. On sale you can find saw blades similar to circular saws, which have an increased tooth set, which significantly reduces the likelihood of jamming. In addition, the difference for the manufacture of such a disc is that other alloys are used, which reduces the risk of destruction of the disc when it is heated.
Further attempts to secure the disc from jamming led to the combination of circular and chain saws in one product. A chain similar to a chainsaw chain moves freely along working surface disk, which absolutely eliminates jamming. There are quite a few modifications of such a hybrid. Craftsmen with the help of such a combined saw successfully saw branches and can even saw not very thick trees.
Another direction of adaptation of circular saws for use on grinders was to reduce the number of teeth. Discs with a diameter of 115 mm or 125 mm are equipped with only three teeth, a disc for a large grinder of 230 mm can have 4 teeth. In this way, manufacturers have tried to compensate for the high speed of rotation of the saw blade.
A completely new direction in the evolution of circular discs was marked by the invention special nozzle suitable for working on different material. Such universal disc made of a special composition - tungsten carbide. There are no teeth on this saw blade at all. This type of disc allows you to cut well the most different materials, it can be considered the most safe disk for sawing wood from all that are used on angle grinders.
Sawing with a grinder
If there is no other way out, that is, there is no special saw for wood (it has broken) or urgent little work is required, of course, the grinder can help out. However, we must remember that the main purpose of this machine is still not in sawing wood. To use an angle grinder as a hand-held circular saw, you will need to stock up on one or more specialized nozzles.
To avoid distortions and jamming, you need to saw in a comfortable position, and fix the tool with both hands. The best results can be obtained if you do not remove the special guide handle, with its help it is much easier to control the angle grinder. Correctly sawing off a workpiece with a grinder is not at all easy, due to the heterogeneity of the wood, the mode of operation will constantly change. Therefore, while working, it is better not to be distracted and monitor how the cut is going.
If you need to use a grinder for sawing wood, it is better to use a circle of small diameter 115 or 125 mm. The 230th circles are much more dangerous, they have a large inertia, in case of an emergency situation, it is not possible to stop their rotation immediately. Installing the saw blade on the angle grinder \. the direction of rotation must be taken into account, it is often indicated on the disk itself in the form of arrows. The teeth of the circular saw have special solderings that increase their performance. A disk installed on the contrary will not be easy to cut. When purchasing saw blades for grinders, you need to pay attention to the following parameters:
- saw blade diameter;
- required depth of cut;
- shape and number of teeth.
If you plan to cut wood infrequently, then it is better to choose a saw blade with teeth that have a variable set. If the main material on which it is supposed to work is chipboard, a saw with a large number it is better not to take teeth. If the grinder will be used in the construction of a log structure, it is better to purchase a chain saw. Sawing boards will require paying attention to the depth of cut and the diameter of the blade.
Circular Saw will last longer, if the teeth that have become dull during operation are sharpened, it is better to entrust this to a specialist. In order to sharpen the saw, the same grinder can be used only with a special abrasive nozzle. Also for this operation you will need a stationary vice.
The modern grinder is often used to perform various works in the process of repair, construction. Such a tool can be called universal. The grinder easily cuts almost any object, grinds, sharpens, polishes and peels. To do the work with the help of a grinder, it is qualitatively necessary to select the right discs, taking into account the type of tool.
Discs for grinders on wood
Angle grinder (grinder) performs a wide range of different operations rotational movements interchangeable disks or nozzles. The most commonly used circles for metal, stone, wood. All of them are divided into three main groups:
- Cut-off
- Sharpening (cleaning)
- Grinding (roughing)
Each group has its own types of discs, which are designed for a specific type of work, including wood.
Woodworking discs look like a regular circular wheel, you need to know how to work with them, because careless movements or inattention can lead to serious injuries. The protective cover on the disc serves as a good protection, so it is better not to remove it from the tool and, for your own safety, use a wheel with fine teeth. According to experts, it is best to work with wood nozzles without a strong feed and try to permanently fix the angle grinder using a special device for this.
The most common can be circles on wood - milling cutters, they look like metal circles with teeth, they are specially made for cutting wood. Circles can be different in size, depending on the thickness of the timber, the diameter of the cutter is selected.
For sawing wood, only saw blades and right choice gives a wide range of possibilities. If you know how to use the tool, you can even make cutting at an angle.
Disc production
There are two types of saw blades for a grinder on wood - monolithic and with carbide soldering at the ends of the teeth. If there are such solderings on the saw blade, then they do not wear out so quickly, they do not require wiring, they cut better, but they need to be sharpened only on special machines.
For the production of saw blades, only carbide sheet steel. It guarantees the product high resistance to mechanical damage and temperature fluctuations. In the production process of the saw blade, great attention is paid to the weld, it connects the body of the blade with the teeth, so its quality is always under control.
The speed and frequency of cutting is affected by the number of teeth on the wheel, the greater the frequency of the teeth, the better the cutting of wood will be, but at the same time the speed of work decreases. When there are fewer teeth on the cutter, the speed increases, but the cleanliness of the cut deteriorates.
Influence of disc teeth
The end result of working with wood depends not only on the frequency of the teeth, but also on their shape. Universal saw blades can be called milling cutters with variable teeth, they work well with hard and soft woods. Products with trapezoidal teeth are only suitable for working with soft materials. For draft version fit circles with straight teeth.
When processing valuable breeds wood, you need to use thin saw blades, they are great for sawing or processing expensive wood. There are also "thin +" discs, where material is used with an additional chipper, it reduces the blocking of the saw during its operation. This saw blade is suitable for longitudinal and cross cutting of wood, as well as other materials. Similar materials from high precision cuts are also used in furniture and woodworking industries.
Features in working with saw blades
When working with a saw blade for wood, special care and skill must be exercised, it is best put on special form
and goggles and gloves. The complexity of working with wood lies in the fact that the tree is easier to cut, so it is necessary to observe control in the operation of the tool. Experts recommend using a tool of low power and speed when working with wood, the best option is 1,000 rpm.
Equally important is the quality of the grinder, as well as the cutter, the final result of the work and its safety will depend on this. It is best to give preference to a proven tool, to hear the opinion of experts in order to be sure of a positive result.
grinding wheels
For execution various works with the help of grinders are made grinding and polishing wheels, They may be:
- spongy
- Felt
- With replaceable sandpaper
- Cloth
The material is selected depending on the surface to be sanded. To process wood species, petal grinding wheels are used, they are made of sandpaper, which is fixed on a hard frame. Sandpaper it can be coarse and fine grain, the marking can be seen on the product itself.
If planned make wood smooth, then it is best to use a fine grit wheel, to remove a small layer of wood - medium grit. If you need to remove old paint, then you need to apply a coarse-grained circle.
According to their design, grinding wheels can be petal, movable and solid. Flap gives the smoothest surface to wood, therefore they are used as finishing circles.
Conclusion
When working with an angle grinder, you must always follow safety precautions. It is good when the tool is equipped with a persistent handle and a protective cover. Devices are considered safe, in the edge of which there is a chain from a chainsaw, it is specially installed there. In the event that one of the teeth is jammed, the disc rotates idle, and this reduces the risk of injury.
