Wood disc for grinder: choosing the right tool
The grinder, or angle grinder (USM), is a very popular tool that 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 its help. To process this material, it is necessary to choose the right wood disc for the grinder. There are many varieties of nozzles that differ in characteristics and purpose.
Varieties of discs for the grinder: the most suitable circles for wood
The range of attachments for this tool is quite wide. The products are classified according to their intended purpose, depending on which 3 main groups of circles for earwax can be distinguished:
- saw blades;
- with diamond coating;
Saw blades. They are similar to standard saws, but are made of other materials. The most common option is tungsten carbide discs. They are not suitable for working with wood.
With diamond coating. 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 process metal parts, as well as elements made of stone and concrete. Such disks are not used for the tree.
Pay attention! The use of USM requires compliance with certain rules. One of them claims that it is impossible to use circles with a larger diameter than indicated in the device passport.
Abrasive. They are highly versatile. Abrasive discs are used not only for cutting, but also for grinding and polishing surfaces. Products from this group are also used for wood processing.
These products are differentiated by another feature – dimensions. The modern market provides a wide range of products, the sizes of which range from 115 to 230 mm. The 115 mm wood grinder disc is the most compact and is used for fast and accurate cutting of the material. It is worth noting that the largest discs are not suitable for working with wooden surfaces.
Types of disks on wood for USM: design options
Many experts do not recommend using a grinder for cutting and processing wood. This is explained by the principle of operation of the device and the characteristics of the material itself. However, the variety of USM discs is growing every year. They can be divided into several types according to the specifics of their work.
Circular saws. Such circles on wood for the grinder are used, as a rule, for more technological equipment, but many install them on the USM. They are divided into two types: large diameter with soldering and more compact, without soldering.
Chain. Ideal for working with wooden materials. Many people are interested in the question of whether it is possible to cut a tree with a grinder. There is no unambiguous answer to it, but 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 often used to perform smooth cutting of the board. It can also be used to 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. Such products perfectly cope with their functions. They can be used to cut wood along and across the fibers. In addition to standard functions, such discs are used to organize grooves in workpieces.
Segmented (material – carbide-tungsten). Such products have appeared relatively recently, but have already gained huge popularity. A distinctive feature of such products is the absence of teeth. The edge of the disc consists of segments that are characterized by high strength.
Useful information! With the help of a segment nozzle, you can work with wood of any strength and viscosity. It is characterized by high safety and is able to withstand even metal inclusions present in some workpieces (self-tapping screws, nails, etc.).
Chain saw blades on wood: advantages of application
In this case, the saw wheel is performed using a chainsaw chain. Such a nozzle is the most suitable for working with wood, as it has the greatest efficiency. A chain disk on a tree for a grinder is also considered the safest. The use of this nozzle significantly reduces the likelihood of injury in the event that the tool jams.
If the disk falls on a solid wood element (for example, a knot) during operation, the chain is not destroyed. This happens by turning the base. Such nozzles are very popular when it is necessary to clean the trunk of a tree from bark and knots.
Saw blades on wood for USM with a chain are used for various kinds of work. With the help of them, you can remove tree branches, as well as cut boards of small thickness. The functionality of chain products allows them to be used as stripping tools. They do an excellent job of removing the bark.
With the help of a saw wheel, you can make an even cut of parquet boards, plywood, fiberboard, chipboard, as well as ordinary uncut 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.
Wood cutting disc for grinder: features
For the manufacture of such products, a special material is used – 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.
Discs of this type may have different tooth arrangements. A variety of types of products on this basis allows you to choose the most suitable nozzle for a particular situation. The shape and frequency of the teeth also play a very important role. The most common circle size for working with wood is 125 mm. If you decide to choose the most versatile option of a cutting saw blade on wood for a 125 mm grinder, then it is recommended to purchase a product with beveled teeth.
Useful information! Circles that have straight teeth are best suited for working with soft tree species. Softwood boards are also processed with the help of 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 the help of such a circle, you can cut the following materials:
- USB plates;
- wood-fiber boards.
Saw blades on wood for this type of grinder have some design features that 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 makes it possible 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.
Stripping disc on wood for the grinder: characteristics
With the help of a grinder, you can not only cut and saw off wooden parts, but also carry out stripping work of varying degrees of complexity. The modern market offers a wide range of such nozzles. They are classified according to several indicators: shape, design and purpose.
Stripping circles are used to remove bark from logs or boards. Thanks to them, you can easily remove the excess part of the wood from the end surface of the board. They may have special spikes or crumbs.
Stripping discs on wood for the grinder are also used to level the surface of the boards. Such circles are equipped with special spikes that are placed on a flat plane. This function is very useful, as it allows you to polish the boards from which the flooring is constructed.
On sale you can find stripping products consisting of twisted wire. They are commonly called korschetki. Such nozzles on a grinder for processing wood 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.
Corkscrews are used to remove paint and varnish materials from wooden surfaces. It is important to note that most often such nozzles are used to remove paint and rust from metal pipes.
Pay attention! For wooden parts, it is necessary to choose a thinner wire that will not damage the workpiece itself. These products are suitable for different types of wood.
Stripping discs on wood, equipped with wire coils, are also used for brushing. This event allows you to give the wood an unusual look, artificially age it. However, with the help of a grinder having a stripping wire nozzle, only small volumes of wood can be processed. Thus, it is not recommended to use this element for brushing on an industrial scale.
Grinding and polishing discs on wood for a grinder
Grinding and polishing of wood are carried out by means of special nozzles that are used for the grinder. Such products include a metal base on which the grinding wheel is fixed. Fastening, as a rule, is done with Velcro.

To use such a wood nozzle for a grinder, it is necessary to fix it with a key (horn) on the shaft of the tool. 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 performed by means of Velcro.
Another variant of the grinding wheel for the grinder is the petal. Its design fully justifies its name. It consists of a large number of sandpaper petals located close to each other. If desired, you can choose the necessary paper grain, which allows you to process wooden materials of varying degrees of density.
Despite the fact that the grinder is not considered the preferred tool for wood processing, grinding nozzles are very common. It is worth noting that grinding in this way is not suitable for smooth surface treatment, since even the most gentle versions of the discs for the ear 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. USM is commonly used for materials that will later be painted with paint.
Grinding wheels for wood grinder: rough grinding
Grinding wheels, which are used for USM, differ in the material of manufacture, shape and operational purpose. The wood processing process itself, as a rule, proceeds in two stages. First of all, rough grinding is performed, after which the material is subjected to finishing treatment. Several types of nozzles are used for rough polishing:
- end circles.
Grinding wood with a grinder using a stripping product is most often used to remove a layer of old paint. Sometimes nozzles of this type are used to remove the varnish coating, if it is not possible to eliminate it manually. Such circles can have different relief, on the features of which depends on how efficiently the product will function.
Corkscrews are used for grinding 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 a particular grinding option.
Useful information! For rough processing, a wire of a larger diameter is used.
End discs for grinding wood on a grinder are used in the case 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 saws. The principle of operation of the end nozzle resembles the work of a file. The difference in this case lies in the high efficiency of the USM.
The use of grinding nozzles greatly simplifies the processing of wooden blanks. Such products allow the restoration of old furniture, removing paint and varnish compositions from its surface.
Grinding wheels for the grinder: petal circles
After rough processing, a finishing finish may be needed. Of course, if the wood is further painted, there is no need to bring its surface to a perfectly smooth state. However, in most cases, finishing is a necessary measure. To perform grinding, you can use a common nozzle – a petal circle.
The design of the petal disk model, as mentioned above, includes sandpaper sheets that have a trapezoidal shape. Their grain size is selected depending on the type of wood and the specifics of the work. A grinding wheel on wood of this type is one of the most common. It provides gentle processing of the material and is characterized by a high degree of safety. It is almost impossible to get injured using this disk.
The size of the abrasive coating on the petals depends on 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 such grinding wheels on wood at once. This will make it possible to quickly carry out rough cleaning, and then finish the work with soft petals, bringing the workpiece to the desired degree of smoothness.
The use of such 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 the grinder: 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 may have different grain sizes.
Useful information! Unlike petal attachments, abrasive particles are fixed with Velcro on the surface of the disk, and not on its end part.
A grinding disc for a wood grinder of this type has one advantage – ease of replacement. This procedure is performed without removing or disassembling the main nozzle, so it is quite convenient to use such disks. Sticky attachments can be easily purchased on the construction market or ordered online. Choosing the right grain size in this case is not a problem. With the help of such devices, you can bring the wooden surface to the desired state.
Polishing, which is performed after grinding, can be carried out using special felt circles. Such nozzles provide maximum smoothness of the working surface, which is difficult to achieve using other tools. A large number of USM revolutions contributes to the uniform polishing of wood.
Felt discs for the grinder include wool (tightly compressed), which can have different characteristics (depending on the need). On the modern market , you can find different versions of nozzles in their composition:
- fine – haired;
- semi – rough – haired;
Nozzles for wood processing are characterized by high efficiency and quality. Alternate use of these disks allows you to achieve incredible results. The wood surface after their use can be compared with a mirror surface.
Safety rules when working with a wood grinder
The use of USM for wood processing requires a serious approach. Improper work with the grinder can lead to injury, therefore, before using it, experts advise you to pay attention to some rules for the operation of the device. For example, before replacing one nozzle with another, you need to disconnect the USB cable 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.
Pay attention! In no case should you remove the casing, which is used for protection, from the grinder. In case of breakage of the circle, this element will protect your face and other parts of the body from injury by shrapnel.
Processing of wood material with the use of USM should take place in the presence of protective gloves. Sawing and cutting discs on wood are best used on medium-sized (in terms of power) devices. This is explained quite simply: if the saw gets stuck, then you have a high chance of holding the tool in your hands. With a powerful device, it will be much more difficult to do this.
For sawing logs and boards, it is recommended to use nozzles that have small teeth. The smaller their dimensions, the less effort it will take to cut. Among other things, it reduces the likelihood that solid wood fibers will meet on the path of the disk.
Any Bulgarian must necessarily be equipped with a speed controller, which must be moved to the minimum position. While working with cutting discs for the grinder, it is very important to observe a right angle. Otherwise, the cutting process will be uneven, and the device itself may jam.
USM can be used for wood processing, however, before starting operation, it is necessary to study the technical features of various nozzles. Products that are used for grinding and polishing do not carry any danger, and they are easy to use. Discs for cutting wood material require careful selection. During operation, it is necessary to observe safety regulations and not deviate from them.
