Wood is a specific heterogeneous material that requires special wheels to work with. Discs for grinders for metal are categorically not suitable for cutting wood! Otherwise, the disk may be destroyed during operation.
The saw blade for wood for the angle grinder is the same as for circular saw but smaller diameter. In most cases, discs with a diameter of 115 mm and 125 mm are used, which can be bought in our online store.
Attention! Working with a saw blade is extremely dangerous and requires skill with an angle grinder and great care. When sawing, it is possible for the blade to jam in the wood, which will lead to the tool being pulled out of your hands and serious injury. It is categorically impossible to cut wood with a grinder "on weight". The tool must be securely fixed on the table.
Choosing a saw blade for a wood grinder
When choosing a saw blade for wood, pay attention to the shape of its teeth, which can be alternately beveled, straight and trapezoidal. In our online store you can buy wood circles for a grinder with variable beveled teeth with a diameter of 115 and 125 mm. They are suitable not only for sawing wood, but also for cutting aluminum and laminate.
Another factor to pay attention to is the number of teeth on the disc. The higher the tooth frequency, the cleaner the cut will be.
Bulgarian, or angle grinder (angle grinder), is a very popular instrument which is versatile. It is used in the process of performing most construction work. Many people are interested in the question of whether it is possible to cut a tree with it. To process this material, it is necessary to choose the right wood disc for the grinder. There are many varieties of nozzles, differing in characteristics and purpose.
The range of nozzles for this tool is quite wide. Products are classified according to their purpose, depending on which 3 main groups of circles for angle grinders can be distinguished:
- saw;
- With diamond-coated;
- abrasive.
Saw. They are similar to standard saws, but are made from other materials. The most common option is tungsten carbide discs. They are not suitable for woodworking.
Diamond coated. This group of circles for the grinder is the most extensive. The high popularity of diamond-coated nozzles is due to a wide operational spectrum. With the help of such circles, it is possible to carry out processing metal parts, as well as stone and concrete elements. For a tree, such disks are not used.
Note! The use of angle grinders requires compliance with certain rules. One of them states that you can't use circles. 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 sign - dimensions. The modern market provides wide selection products, the dimensions of which vary from 115 to 230 mm. The 115 mm wood grinder disc is the most compact and is used for fast 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 due to the principle of operation 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 according to the features of the work into several types.
Circular saws. Such wood circles 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 soldered and more compact, without soldering.
Chain. Ideal for working with wood materials. Many people are interested in the question of whether it is possible to saw a tree with a grinder. There is no single answer to it, however, chain products are maximally adapted for this purpose. The edge of the circle in this case is equipped with a chain on which the teeth are located. Such a design has many advantages. This nozzle is most commonly used for smooth cutting boards. With it, you can process other materials: chipboard, fiberboard, plywood.
Saws with a small number of teeth. This kind of circles was invented specifically in order to ensure maximum human safety when working with wood. Compact products belonging to this group have 3 teeth, and larger ones - 4. This group also includes cutting discs for a 125 mm wood grinder. These products do their job well. They can be used to cut wood along and across the grain. In addition to standard functions, such discs are used to organize grooves in workpieces.
Segmental (material - tungsten carbide). Such products appeared relatively recently, but have already gained immense popularity. Distinctive feature such products - the absence of teeth. The edge of the disk consists of segments that are characterized by high strength.
Useful information! With the help of a segment nozzle, you can work with wood of any strength and viscosity. It is highly safe and is able to withstand even metal inclusions present in some blanks (self-tapping screws, nails, etc.).
Chain saw blades for wood: application advantages
AT this case saw blade performed using a chainsaw chain. Such a nozzle is the most suitable for working with wood, as it has the highest efficiency. A chain drive on a tree for a grinder is also considered the safest. Using this attachment greatly reduces the chance of injury if the tool jams.
If the disk hits a solid element of the tree (for example, a knot) during operation, then the chain is not destroyed. This is done by turning the base. Such nozzles are very popular when it is necessary to clean the trunk of a tree from bark and knots.
Wood saw blades for angle grinders with a chain are used for various kinds of work. With their help, you can remove tree branches, as well as cut boards of small thickness. Functionality chain products allow you to use them as peeling tools. They do an excellent job of removing the bark.
With the help of a saw blade, you can make an even cut parquet board, plywood, fiberboard, chipboard, as well as ordinary unedged and edged wooden products. It is important to remember that the thickness of the material to be processed with such a nozzle should be no more than 4 cm. Otherwise, the device is likely to overheat.
Cutting disc for wood for a grinder: features
For the manufacture of such products are used special material- tungsten carbide. This is explained by the following: when working with a 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 the safety of work, but the cost of such products is quite high.
Disks this type may have a different arrangement of teeth. A variety of types of products on this basis allows you to choose the most suitable for specific situation nozzle. 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 universal option cutting saw blade for wood for a 125 mm grinder, then it is recommended to purchase a product with beveled teeth.
Useful information! Wheels that have straight teeth are best for working with soft woods. Boards from conifers are also processed using such nozzles.
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 with an average density. With this wheel, you can cut the following materials:
- USB plates;
- wood fiber boards.
Saw blades for wood for this type of grinder have some design features, which are determined by their purpose. For example, during operation, products easily overheat, so they have special slots that can be empty or filled with copper. Such a measure allows you to compensate for the thermal expansion of the metal that occurs at high speeds. The width of such slots can be different, but not more than 2 mm. As for their depth, it does not exceed 20 mm.
Grinding disk for wood for a grinder: characteristics
With the help of a grinder, you can not only cut and saw off wooden parts, but also carry out peeling work of varying degrees of complexity. The modern market offers a wide range of such nozzles. They are classified according to several indicators: form, design and purpose.
Peeling wheels are used to remove bark from logs or boards. Thanks to them, you can easily remove the excess part of the tree from the end surface of the board. They may have special spikes or crumbs.
Peeling discs for wood for grinders are also used to level the surface of the boards. Such circles are equipped with special spikes, which are placed on a flat plane. This feature is very useful, as it allows you to polish the boards from which the flooring is constructed.
On sale you can find peeling products consisting of twisted wire. They are usually called korshchekami. Such attachments for a grinder for woodworking are of two types, depending on the features of their structure. The first option provides for the presence of 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 eliminate paintwork 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 wood.
Peeling discs for wood, equipped with wire coils, are also used for brushing. This event allows you to give wood unusual view, artificially age it. However, with the help of a grinder with a peeling wire nozzle, only small volumes of wood can be processed. Thus, for brushing in industrial scale this item is not recommended.
Grinding and polishing discs for wood on a grinder
Grinding and polishing wood is carried out using special nozzles that are used for grinders. Such products include a metal base on which is fixed grinding wheel. Fastening is usually done with Velcro.

To use such a wood attachment for a grinder, it is necessary to fix it with a key (open-end) on the tool shaft. Quite often, it is implemented complete with a special transition element, thanks to which it becomes possible to quickly attach to the drill chuck. In turn, polishing requires the use of a more gentle material. Therefore, nozzles of this type are equipped with felt discs. Their fixation is also carried out with Velcro.
Another option for a grinding wheel for a grinder is a petal one. Its design fully justifies its name. It is made up of many petals. sandpaper, located close to each other. If desired, you can select the desired paper grain, which allows you to process wooden materials varying degrees of density.
Despite the fact that the grinder is not considered the preferred tool 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 options for angle grinder discs leave small scratches on the wood. If you decide to perform 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 with paint.
Grinding wheels for grinders on wood: rough grinding
Grinding wheels that are used for angle grinders differ in the material of manufacture, shape and operational purpose. The process of wood processing, as a rule, proceeds in two stages. First of all, rough grinding is performed, after which the material is subjected to finishing. For rough polishing, several types of nozzles are used:
- peeling;
- corsets;
- end circles.
Sanding wood with a grinder using a peeling product is most often used to remove a layer of old paint. Sometimes nozzles of this type are used to remove varnish if it cannot be removed manually. Such circles can have a different relief, the characteristics 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 the rigidity, they are also divided into types. If necessary, it is possible to select the right tool corresponding to one or another variant of grinding.
Useful information! For rough processing, a larger diameter wire is used.
End discs for grinding wood on a grinder are used when it is necessary to adjust the size of the part from the end. Often, such products are used for the usual alignment of the side surface with uneven cuts. The principle of operation of the end nozzle resembles the operation of a file. The difference in this case lies in the high efficiency of the angle grinder.
The use of grinding attachments greatly simplifies the processing of wooden blanks. Such products allow for the restoration old furniture, removing paints and varnishes from its surface.
Grinding discs for grinders: flap discs
After rough processing, it may be necessary fine finish. Of course, if the wood is to be further painted, there is no need to bring its surface to a perfectly smooth state. However, in most cases finishing is necessary action. To perform grinding, you can use a common nozzle - a petal circle.
The design of the petal disc 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 handling of the material and is characterized by a high degree of safety. It is almost impossible to get injured using this disc.
The size of the abrasive coating on the petals determines the efficiency and speed of wood processing, as well as its appearance. For maximum smoothness, it is customary to use fine-grained products. Experts recommend using several of these grinding wheels on wood at once. This will enable you to quickly rough cleaning, then finish the work with soft petals, bringing the workpiece to the desired degree of smoothness.
The use of such a nozzle requires a certain skill from a person. Therefore, before using the petal circle, it is recommended to practice on wooden parts.
Grinding wheel for grinders: soft processing and polishing
For 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.
Useful information! Unlike petal nozzles, abrasive particles are fixed with Velcro on the surface of the disc, and not on its end part.
Grinding disc for 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 on the construction market or ordered on the Internet. The choice of the desired grain size in this case is not a problem. With these devices, you can wooden surface to the desired state.
Polishing, which is carried out after grinding, can be carried out using special felt wheels. Such nozzles provide maximum smoothness of the work surface, which is difficult to achieve using other tools. A large number of revolutions of the angle grinder contributes to uniform polishing of the wood.
Felt discs for the grinder include wool (tightly pressed), which can have different characteristics (depending on the need). On the modern market you can find various options for nozzles in their composition:
- fine-haired;
- semi-coarse;
- coarse-haired.
Woodworking attachments are different high efficiency and quality. Sequential use of these disks allows you to achieve incredible results. The wood surface after their use can be compared with a mirror.
Safety rules when working with a wood grinder
The use of angle grinders for wood processing requires a serious approach. Wrong work with a grinder can lead to injury, so before using it, experts advise you to pay attention to some rules for operating the device. For example, before replacing one nozzle with another, you need to disconnect the angle grinder from the network. How to change the disk on the 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 required to unscrew the flange holding the element.
Note! In no case should you remove the casing, which is used for protection, from the grinder. In the event of a wheel breakage, this element will protect your face and other parts of the body from injury from splinters.
Treatment wood material With using angle grinders must be done with protective gloves. Sawing and cutting discs for wood are best used on medium (in terms of power) devices. This is explained quite simply: if the saw jams, then you have a high chance of holding the tool in your hands. With a powerful device, this will be much more difficult.
For sawing logs and boards, it is recommended to use nozzles that have fine teeth. The smaller their dimensions, the less effort will be required to cut. Among other things, it reduces the likelihood that hard wood fibers will meet in the path of the disc.
Any Bulgarian without fail must be equipped with a speed regulator, which must be moved to the minimum position. When working with cutoffs, it is very important to maintain a right angle. Otherwise, the cutting process will be uneven, and the device itself may jam.
Angle grinder can be used for wood processing, however, before use, you should study technical features various nozzles. Products that are used for grinding and polishing do not carry any danger and are easy to use. Blades for sawing wood material require careful selection. During operation, it is necessary to observe the safety regulations and not deviate from them.
Bulgarian or angle Sander allows processing various materials, including wood. If it becomes necessary to cut metal, they resort to using an abrasive disc on a grinder. If you need to cut a brick or ceramic tiles, then diamond discs come to the rescue, due to their high strength and durability. What to do if you need to saw or grind wood? To do this, you will need to purchase a special disc for a wood grinder.
Initially, you need to decide on the tool with which you plan to cut wood. It is known that discs are produced under standard sizes Bulgarians. The smallest diameter is 115 mm, but such a tool is used in extreme cases. The main advantage of such a grinder is its compactness, but it is extremely inconvenient to work with such a tool for a long time. The best option for woodworking - this is a grinder with a 125 mm disc. It is this size of the circle for wood that is the safest, and therefore it has become widespread.
To work with angle grinders on wood, a special disk is required. It is strictly contraindicated to cut wood with abrasive or diamond wheels. This will not help to cope with the task, but rather lead to the destruction or overheating of the tool. When choosing a circle for a wood grinder, it is important to pay attention to the inner diameter of the shaft, which, according to the standard, is 22.2 mm.
It's important to know! Older models of angle grinders may have a different shaft diameter, so this point is important to consider when buying the appropriate circle.
The optimal circle for woodworking has following parameters: 125x22.5 mm. Bulgarians for discs from 150 mm and above are not recommended for wood, as the risk of serious injury increases. It is better to use tools for cutting or grinding wood under 125 or 115 circle diameters.
Varieties of grinding wheels for wood
When choosing nozzles for a grinder for woodworking, you should know that there are not only cutting discs, but also grinding discs. To grind wood with an angle grinder, a petal nozzle is used. Working surface such a consumable consists of several layers of sandpaper, which has varying degrees roughness. The lower the roughness, the softer the sanding can be. petal circles allow not only grinding, but also polishing work, which depends on the degree of granularity.
In addition to petal, there are also such types of nozzles that are very popular - these are sticky discs. They are known for their versatility, as they allow quick replacement using a special Velcro. The cost of such consumables is much lower than that of the first option, but at the same time they have a shorter service life.
Grinding and polishing discs for the grinder must be of high quality, which affects not only the quality doable work but also on the safety of the master. The quality of wood processing is influenced by such a factor as the degree of its dryness. Processing raw wood is prohibited, as the result of such manipulations can be unpredictable.
If it is required to carry out peeling work, which is often carried out as an initial processing, then special peeling nozzles are used. They are mainly used for those purposes to remove a layer of paint from a painted surface. Such nozzles are metal plates, inside of which there is a metal bristle made of wire.
It's important to know! It is not difficult to carry out grinding or polishing wood with a grinder, but it is important to observe safety precautions.
Varieties of cutting wheels for wood
If you need cutting discs for a grinder for wood, then you should initially pay attention to such parameters as the diameter of the circle, the depth of cut and the characteristics of the teeth. Depending on the wood material, it is necessary to use saw blade on wood with the following teeth:
- Universal or beveled wood saw blades for grinders are best used if it is planned to carry out work rarely in extreme cases, and any type of wood can be used as processed materials.
- Wood discs with straight teeth are recommended if technological process provides work with coniferous and soft breeds of wood.
- The trapezoidal shape of the tooth is suitable for cutting medium-density chipboard. Most often, such a tooth is universal and suitable for sawing hardwoods.
Features in working with saw blades are due to the following factors:
- The thickness of the circle must be within 2 mm.
- The depth of the cuts made can be within 20 mm.
- Cutouts can be empty or filled with copper.(!)
It's important to know! When working with saw blades or cutting discs for wood grinders, you should be especially careful and careful. Without special need and experience, it is better not to carry out such work or replace them with other tools.
What you need to know when working with angle grinders
Not only power tools, but also hand tools are a serious danger if safety rules are not followed. The nozzle on the grinder for cutting wood in this case is no exception. At the work of the angle grinder With woodworking discs, it is important to pay attention to the following points:
- Choose the right circle for the tool: according to the diameter of the outer and landing, and also depending on the type of wood.
- Select the appropriate operating mode for the tool.
- Do not use wheels that show obvious signs of damage.
- Resort to application individual means protection.
It is not necessary to carry out work without the use of a protective cover, with the exception of carrying out manipulations on peeling, grinding and polishing wooden surfaces. It is especially dangerous to work with saw wheels. It is strictly forbidden to resort to installation on angle grinder discs from a circular or other instruments. For angle grinders, you can only use consumables that are directly intended for it.
In conclusion, it should be summed up and noted that grinder wheels for woodworking are no less popular than abrasive wheels. After all, the use of such consumables greatly facilitates the work of a person, and also significantly saves time.
Bulgarian, whose real name is an angle grinder, angle grinder is a universal tool. Almost never do without it. construction works. But in order for the tool to last a long time, you need to choose the right one. grinding discs. A disc for wood is fundamentally different from a disc for metal. What are its features, and what are the varieties?
To date, the entire range is divided into three main areas:
- Saw discs. They resemble a regular saw, but are made from completely different materials. Until recently, such copies were not found, but now they are sold completely freely. The most preferred option is tungsten carbide.
- Diamond coated disc. The most popular variety. In turn, it is divided into continuous and segmented. The scope of their application is different, but there is common feature- high-quality and accurate result of work on concrete, metal or stone.
- Abrasive. Universal consumable suitable for any type of surface. Qualitatively cuts and grinds, and also polishes.
Of the listed discs, the first and second are not suitable for wood. Natural wood has a very dense structure, and if you use diamond disc, then the grinder will overheat until it breaks.
Also, the products differ in diameter. The most practical ones have a diameter of 125 mm, in rare cases a compact disc is needed - 115 mm. There are specimens up to 230 mm, but they are not suitable for wood. Their use may result in injury.
Choice of cutting wheels for wood
Cutting discs are divided into three parameters - diameter, depth of cut and shape / frequency of the teeth. Choosing desired option, there are several things to consider: how often the product will be used and for what kind of wood.
Coniferous and other soft wood easy to cut with straight teeth. If you plan to cut different wood, it is better to take a universal circle with variably beveled teeth. There are also trapezoid teeth which are ideal for sawing through medium density wood and solid woods.
Choice of grinding and polishing wheels
If cutting material requires certain skills, then almost anyone can grind. This operation is usually used petal discs. Such a disc consists of several petals of emery, arranged in a circle. Sandpaper provides soft sanding.
Another variant - abrasive disc on Velcro. It is convenient to use, but even more convenient to change. Such circles do not last long, but also have a low cost. And, of course, they are many times more effective. manual method sandpaper processing. For example, using such a circle, you can polish parquet.
Tree preparation
Whatever the disc for the grinder, the work cannot be done well if the wood is not properly prepared. Here are some tips for this:
- the tree must be thoroughly dried;
- special peeling nozzles are suitable for removing paint or varnish from the surface;
- work is carried out in two stages, roughing and finishing.
Discs and other tools that you will need for full-fledged grinding or polishing of wood:
- Cord brushes designed for rough grinding surfaces. Helps to give the workpiece an acceptable shape.
- The next step in processing a natural wood blank is to use sanding head. If the subject is complex, you will also need to apply radial stripes.
- A felt circle made of pressed wool (coarse, fine or semi-coarse) will help get rid of the slightest roughness. With their help, the surface can be made almost mirror.
As you can see, when using various nozzles, the grinder becomes universal tool for woodworking.
Saw (chain wheels)
Suitable for cutting boards less than 4 cm thick. Use requires extreme care. During non-working hours, the disc should be kept in a case, and during operation it should be used only at those speeds that are written on the product itself.
Goggles and protective gloves are also required when working. It is important to remember that on the grinder, in no case should you use ordinary circles designed for a circular saw.
Using an angle grinder for milling
A wood cutter for a grinder in non-professional hands can be dangerous. For a specialist, its use is permissible.
The cutter helps to level the edge, make grooves, cut blanks and cut out bowls for log cabins. Even on inhomogeneous wood, the tool will not jam or kick back. However, before using it, it is important to carefully read the instructions, as well as observe the necessary speed.
The choice of cutters for angle grinders is quite wide, no less than for a manual milling machine. They are not designed for precise processing, but are quite suitable for shaping.
Safety rules during work
In order for the use of a wood disc for a grinder to bring only benefits, and not injuries and damaged products, several important rules must be observed:
- choose the right circle according to size and properties;
- the mode of operation of the machine must comply with the requirements on the disk;
- in no case should you use damaged circles;
- protect your hands and face with special devices and overalls.
The nozzle should fit effortlessly under the casing of the angle grinder. If you cannot do this, then do not remove the casing, it is traumatic.
Why can't saw blades be used with an angle grinder?
The hardness of a tree can be different even within a few centimeters. Also, it can come across clots of resin and knots. All these uneven areas lead to the fact that the saw blade stops abruptly, as a result, the angle grinder breaks out of his hands.
Bulgarian, being a universal tool for home master or a professional, it is used when performing a variety of operations for 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 a grinder, and what nozzles are needed for this?
The only operations with wood that can be performed with an angle grinder (angle grinder) without fear are grinding and peeling, and then using special nozzles. Cutting wood of course will work, but it is strictly forbidden! The Internet is full of shocking photos showing what the use of an angle grinder as a tool leads to. cutting tool on wood.
The main arguments against use of angle grinders for sawing, the following.
- This machine is not designed for sawing wood.
- Since the wood has a viscous and soft structure, the saw blade can jam in it. As a result, the grinder is often pulls out of hand, and it flies in an unpredictable direction (in the leg, on the arms, in the stomach, etc.), causing deep wounds to a person or amputation of fingers. Even fatal cases have been documented.
- When cutting wood, it happens very quickly saw blade heating which causes it to lose strength. At the slightest distortion or excessive pressure, it can fly apart. Since the spindle speed of the angle grinder is high, the fragments of the tool scatter at the speed of shrapnel and enter deeply under the skin of a person. The user is lucky if the fragments do not fly into the head or eyes.
- Despite the risk of using saw blades with teeth, some angle grinder users ignore this fact and continue to install circular discs with large teeth or improved carbide tips. If, when cutting wood, a hard knot or the remainder of a nail gets into it, then the tooth or solder breaks off, clings to the next saw tooth and is thrown out at the speed of a bullet. The consequences can only be guessed at.
- Ignoring all the warnings, angle grinder users install a circular saw of a larger diameter on the machine than the protective cover. This is the most dangerous option for using angle grinders.
Based on the foregoing, sawing a tree with an angle grinder is possible only at your own peril and risk, and then if this is a single or infrequent operation.
If you have to cut a tree constantly, then 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 make a circular out of it, fixing the apparatus rigidly on the frame.
What are the circles for cutting wood
Despite the danger of using angle grinders for cutting wood, tool manufacturers still produce saw blades for it.
Circular saws
The photo below shows "dangerous" saw blade for the grinder, although its diameter corresponds to the protective casing of the grinder with a maximum working tool of 180 mm. There are saws with soldering and a smaller diameter.
On the next photo you can see a less dangerous version of the circular saw. It provides protection against jamming, and it is implemented due to a small set of teeth in different directions.
Chain saws
A saw blade made using a chainsaw chain reduces the risk of injury when the tool jams. This nozzle is designed in such a way that the chain fixed on the inner disk (base) has non-fixed landing.
If the chain is jammed in the material being processed, the base continues to rotate, and the tool does not pull out of the hands.
These chain discs for the grinder have many modifications, and with their help you can cut branches in the garden, as well as use them for rough cutting of thin boards.
In addition to cutting chain disc can be used and how rough, for example, for removing the bark, as well as for cutting cups in log cabins and modeling.
Saws with few teeth
Also for the 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 diameter discs can have 4, as shown in the following photo.
These discs for grinders remarkably cut wood both along the fibers and across. In addition, with the help of a saw blade, you can cut grooves, make various cuts and spikes in the workpiece. But when working with angle grinders, you should follow one rule: you need to install on the grinder cutting disc of such a diameter for the use of which it is designed by the manufacturer, that is, do not exceed its dimensions. Circles of smaller diameter can be set.
Tungsten Carbide Discs
Tungsten carbide discs for angle grinders have appeared on the market not so long ago and have made a kind of revolution in the field of woodworking.
The universal disc has no teeth. Instead of the latter, there are segments around the circumference of the nozzle. cutting disc similar in appearance to diamond circle for cutting concrete. With the help of a tungsten carbide wheel for an angle grinder, you can very easily cut 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 take into account possible consequences use of circular saws, this is a low price for safety.
Wood sanding attachments
For woodworking, except cutting wheels, there are specially designed for installation on angle grinder nozzles, with which you can peel, grind, brush and mill wooden surfaces.
Peeling nozzles
If you need to remove a layer of paint or other coating from a wooden surface, you can install a peeling nozzle on the grinder. Available for sale a large number of various nozzles for peeling works. They differ in shape, design, and in the types of work that can be performed with this tool.
The photo below shows disc nozzles. with spikes or chips with which you can easily remove upper layer wood, grind the end of the board, etc.
The next cutter, due to the fact that the spikes on it are located on a flat plane, allows leveling various wooden surfaces. For example, if 2 boards on the floor at the end connection are on different height. With this nozzle, the defect is easily eliminated, and the boards are joined in the same plane.
There are also peeling nozzles 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 coils of wire clamped in its central part.
These brushes are used if you need to quickly peel 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 stripping, this cork brush is often used for brushing wood, that is, giving it the effect of aging. If this effect is to be applied on large surfaces, in professional field, then for brushing it is better to use special manual machines with wide brushes.
Sanding and polishing tips
For grinding various surfaces, including wood, commercially available special nozzle for angle grinders, consisting of metal base, which is attached with Velcro emery grinding wheel. The nozzle is screwed onto the grinder shaft and tightened with an open-end wrench.
Often it is equipped with an adapter for fixing it in a drill or drilling machine chuck.
