Choosing a wood disc for a grinder, grinding angle grinder. Wood saw blade for an angle grinder: choosing the right tool Wood saw blade for an angle grinder

corner Sander(angle grinder)

A wide range of power tools on the Russian market is designed to facilitate various types of manual work. If in the professional field the purchase specialized equipment is simply necessary, then in everyday life it is not always rational to spend money on an expensive tool that, after doing a certain job, may not be useful at all. The most popular power tool is the angular Grinder(UShM). The scope of its application is not limited to metal processing - grinding wood with a grinder is done using special nozzles.

For those who do not know "Is it possible to process wood with a grinder?" this article will be helpful. To perform grinding and polishing of wooden products or large surfaces of the array, you will need to purchase the appropriate nozzle - a circle. For grinders different sizes nozzles are selected, designed for a certain speed of rotation. Special discs designed for wood processing must be carefully selected. The disc must match the dimensions of the tool; a special nut is used to secure it.

When working with angle grinders, it is necessary to strictly observe safety precautions and use only factory wheels that are suitable for a particular model of power tool.

Wood processing grinder

Coarse wood grinding discs for angle grinders

There are several varieties of circles that differ in shape, material of manufacture and purpose. As a rule, the wood blank must first be subjected to a rough surface treatment, after which it is subjected to fine or final detailing of the coating with abrasive segments.

For such work, a special attachment for a grinder for grinding wood is designed. The most requested are:

• Roughing circles. Such a grinding attachment for a grinder is best used to remove a layer old paint. Suitable for lacquered finish which cannot be removed manually. It can be a wooden floor painted several times or a window sill. The design of abrasive discs consists of a disc and metal bristles made of elastic wire. Nozzles are issued with different arrangement of a steel bristle. Depending on achievement desired effect the villi can be placed along the entire perimeter of the disc parallel to the instrument or perpendicular to the segment - as in a conventional brush.

• Cordbrushes are a coarse abrasive coated disc designed for rough sanding and removing roughness on a wooden surface. With the help of this tool, the wood blank acquires its final shape. Productivity of works in comparison with the usual manual tool is much higher.

• End discs. Nozzles are used when you need to align the product from the end. Such processing requires oblique cuts and the edges of the workpiece. The execution technique is identical to the file, but the abrasive is more effective than hand tool. When working with a segment, it is important to have skills and then such a simple tool can completely replace moulder cutter in terms of edge processing.

With the help of a grinder for polishing wood, you can completely restore furniture covered with varnish and paint. After such a stripping, the thickness of the wooden base practically does not decrease, but the newly painted furniture will look beautiful and impressive.

When performing grinding work with a grinder, the choice of tool is not so significant compared to the presence of well-dried wood and the absence of cracks on the surface.

Grinding wheels for gentle processing and their areas of application

To perform wood grinding with a grinder, nozzles of a universal design and with a special gentle coating are used. Such mechanical restoration intended for the production of certain works:

• The petal disc is used for grinding the array. The design of this segment corresponds to its name. Its work surface is equipped with large quantity trapezoidal petals sandpaper, which overlap each other like fish scales (three-quarter overlap of the previous row). With this arrangement of the petals, the abrasion of the nozzle occurs much more slowly.

This is the most common type of attachment for a grinder for wood grinding, which performs a soft surface treatment, and the tool itself is less traumatic. To achieve the desired degree of processing and high quality, the disc is selected according to the grain size. The size of the abrasive determines how quickly and efficiently the irregularities on the wooden surface will be removed.

The polished coating at different stages of processing may remain a little rough or be perfectly even without the slightest flaws and hooks. The final result can be achieved with a consistent transition from abrasive discs with a coarse-grained fraction to segments for finer processing. Therefore, you will need several discs per angle grinder for grinding wood, which will change in stages.

To use the petal nozzle, certain skills are required, which means that training before performing responsible work will be simply necessary.

• Wheels for soft grinding. Universal nozzle on the grinder for grinding wood appeared on the market relatively recently and is distinguished by a special design and high functionality. Draft work is intended to be carried out by replaceable discs with the desired grain size, which are attached to the sticky base of the nozzle. In this regard, the abrasive tool received the appropriate name - sticky disc.

The main advantage of a wheel grinder for wood grinding is the quick change of a worn-out removable disc: the whole procedure takes place without removing the main nozzle, which is fixed with a nut. First you need to purchase a sticky attachment for grinding on a grinder, so that later, without any difficulties, you can replace the worn abrasive segment.

How to choose sanding attachments for an angle grinder

Circles should be selected according to the main parameters:

• outer diameter (with large sizes, the processing process is accelerated and the service life is increased);
• bore diameter (circle setting bigger size to a smaller one is possible with the help of a special adapter);
• thickness (the greater the thickness, the longer the segment will last);
• grit (the fraction must correspond to the type of processing: a coarse abrasive for rough work, and a fine one for soft processing and creating a finish coating);
• type of segment (suitable for special nozzles for processing wooden surfaces).

Reference! The diameter of the shaft in modern angle grinders for wood is 22.2 mm.

What you need to know when working with a grinder

Update floor covering(parquet), furniture or facade of the house, where there are wooden structures or individual elements, is performed using a grinder for grinding, which is equipped with different nozzles. Therefore, it is not surprising that angle grinders for wood polishing are in demand among professionals and in everyday life. But in order to choose the right tool for the job, you need to carefully study wooden surface for the presence of fungus, cracks and irregularities. A video is provided to help beginners who want to know "How to properly grind a tree with a grinder".

A grinding nozzle must be selected for each angle grinder model, only in this case will the safe performance of work and high-quality surface treatment be guaranteed. Before you start working with a grinder (wood sanding), you need to make sure that the disk is properly fixed. Move corner car on the surface it is necessary to smoothly and not allow vibration of the tool.

When working with an angle grinder for grinding wood, it is unacceptable to use discs of small thickness (high rotation speed and load lead to a break in the circle, which is fraught with injuries).

The cost of circles for woodworking

The price of a tool for polishing a wooden surface is not high, but depends on the material, diameter and thickness. The table shows average cost abrasive tool in major cities Russia:

Handmade requires application quality tool, and an angle grinder with nozzles greatly facilitates the work and speeds up the process of processing a wooden surface.

1. What are cutting wheels?
2. Work tips

The angle grinder, popularly known as the grinder, is a worthy and versatile tool. It is this equipment that allows you to successfully perform cutting, grinding, polishing, sawing off almost any material. When choosing a grinder, it is extremely important to understand which model is recommended for use. The choice is largely determined by the main purpose of the proposed equipment. Metal and wood will require different types disks and a specific approach, because otherwise the work will not bring the desired results.

Wheels for an angle grinder: we start with market research

The range is striking in its diversity. What are grinding discs and how are their characteristics determined? To fully answer the question, the entire market should be divided into main areas.

1. Abrasive coated wheels. This consumable tool is universal, therefore, with its help, any workpiece can be cut and polished with high quality. In addition, the possibility of polishing is assumed. The abrasive tool is not in vain considered one of the best.
2. Disc for grinder with diamond-coated- one of the most common building tools. These products are segmented and solid, and for each option, its own area of ​​\u200b\u200buse is defined. In each case, the possibility of high-quality and accurate cutting of durable materials is assumed, among which are stone, metal, concrete monolith.
3. Saw blades on the grinder visually resemble modern models saws. However, other alloys are used for their production. Previously, products were rare, but now their prevalence is growing rapidly. Most the best way tungsten carbide grinding wheel.

Taking into account the variety of modern products, you should abandon the senseless and sometimes dangerous attempts to establish a circle from a circular to a grinder. Any circular discs designed for low speeds, and on the grinder there is a risk of warping or destruction of the tool.

How to choose a suitable angle grinder model?

When studying modern circles for an angle grinder, it is important to understand the basic principles for choosing a consumable for an angle grinder. What aspects to take into account?

Grinding wheels have several standard diameters. The most compact model differs in size in 115 mm. However, 125 mm grinder discs are of greater practical importance. Moreover, it was angle grinders for the 125th circles that were most widely used not only among the pros, but among home craftsmen.

Natural wood always turns out to be a specific heterogeneous material, therefore working with it requires special circles. Grinding discs, which are designed for cutting metal or concrete, are categorically not suitable for such processing. Otherwise, the grinder will be destroyed or burned by overheating.

When choosing equipment for grinding, it is important to note that the standard diameter of the installed shaft is 22.2 mm. Previously, there were several divisions, so labeling still plays an important role. Today, for example, a standard saw blade for woodworking has a diameter of 125x22.2 mm.

Although maximum size The angle grinder is 230 mm, such dimensions are undesirable when processing wood. When choosing a tool with a large diameter (from 150 mm), you run the risk of serious injury. The preferred dimensions are 115x22.2-125x22.2 mm. In addition, the 125th circles are able to cope with a fairly large range of production tasks.

Only if you understand the specifics of the equipment used, you can learn how to correctly select discs for a grinder for safe and efficient processing. natural wood.

What are cutting wheels?

Parameters that are used for classification cutting discs on wood:

• Disc diameter;
• Depth of cut wood;
• Characteristics of the teeth: shape, frequency, number.

What to consider when planning to use a cutting disc for a modern angle grinder?

1. If saw blades for wood grinders will be rarely used, and the type of wood being processed will be different, it is best to choose a model with variable beveled teeth.
2. For sawing softwood and softwood, models with straight teeth are suitable. Such saw blades successfully process even the softest wood, guaranteeing a decent work result.
3. Trapezoidal tooth allows universal use. When choosing such equipment, it is best to cut medium density chipboard. Other products can be used if desired.

What parameters should be taken into account for successful work with wood when choosing sawing consumable tools?

1. Rounded cutouts are required, which will be made towards the shaft.
2. The optimal disc thickness is 2 mm.
3. The depth of the cuts made can reach 20 mm.
4. Cutouts are empty, but in some cases they are filled with copper.

Equipment for grinding and peeling work

In most cases, working with materials implies the need not only for polishing, but also for grinding and roughing activities.

Cutting wood is a dangerous activity. At the same time, anyone who has necessary equipment. The most important thing is to understand the principles of technological operations.

Most often used for peeling petal discs to Bulgarian. Having carefully studied the specifics of the product, it is possible to understand how functional and effective it is.

The name gives an initial idea about the features of the device. consumable tool. Its working surface has several petals of sandpaper. This structure is comparable to fish scales. At the same time, this paper with a low roughness allows you to guarantee a soft sanding of natural wood. The quality and degree of processing depends on the grit of the material, so polishing and grinding can be carried out in accordance with the requirements.

The petal disc for the angle grinder is quite popular, but if desired, you can use another consumable tool.

For example, noteworthy sticky universal disc. Modern nozzles on the grinder provide for the possibility of a quick change of Velcro. The price of sticky discs used for basic operations turns out to be lower than that of a solid petal one, but the service life is also shorter. If, nevertheless, a universal sticky circle is chosen for the grinder, then it can be used for processing and grinding various materials, which confirms the demand for this product.

A polishing and grinding tool may be of high quality, but it cannot guarantee the successful completion of the job. What is the reason for this? It's very simple: the wood used must be thoroughly dried. Moreover, raw wood cannot be used. Otherwise, the result will be unpredictable. When choosing a disc for wood, you need to be sure that the material being processed has the right properties.

Sometimes cleaning work is required to remove the old layer of paint or varnish, fungal infections. Polishing and grinding tools always show themselves at a decent level only if the wood is prepared according to technological requirements. Bearing in mind that polishing and grinding discs for grinders are not provided for initial processing, roughing attachments are required.

Choosing similar nozzles for the grinder, maximum benefit they can be felt when cleaning old surfaces that have been repeatedly painted. This is due to the following factor: the nozzles are made in the form of a metal plate, which is densely dotted with wire bristles located closer to the outer circumference, radially or perpendicular to the disk.

Work tips

Finishing work begins only after successfully giving the workpiece a preliminary outline. The results largely depend on what types of nozzles are used to perform the tasks.

Angle grinders are used in the form of a cutter, as well as polishing and grinding attachments. Nozzles on the grinder increase the functionality of the device used.

So, how to carry out the polishing and grinding process when processing wood? What tools do you need to be successful?

1. Brush cord. These tools are ideal for rough wood sanding. The possibility of successful leveling of wood is assumed, with giving the optimal shape to the product.
2. End discs allow easy turning of workpieces. In most cases, such work is required for bevel cuts. Work end disk resembles the interaction of the workpiece with the saw.
3. Flap sanding attachments are the most popular variant of the applied Supplies. The characteristic of the tool determines the possibility of processing various workpieces, including natural wood. It is important to note that the cleaning of complex wooden objects is carried out only using radial strips.
4. Felt circle - allows you to achieve minimal roughness, processed products. The basis is pressed wool, fine-haired, semi-coarse-haired and coarse-haired. Felt working tool allows not only to carry out high-quality processing of wood or other material, but also to give a perfectly smooth surface, comparable to a mirror.
5. A wheel for a grinder designed for grinding is often compared with a disc of the same name. It is important to note that the Velcro circle is universal tool, which has a wide range of applications. Various fixtures for wood processing perform certain tasks, but the grinding wheel sometimes surprises with its versatility and high level efficiency.
6. The chain disc for wood is one of the most productive, but rough ways of processing natural material.

When choosing equipment, it is desirable to take into account not only the diameter, but also each accompanying informative designation. The inscriptions will allow you to determine the purpose of the tool and follow the recommendations during operation. Marking discs, circles and nozzles for grinders is a guarantee of a successful result.

A modern grinder is a convenient and effective tool. For quality work special nozzles and discs are required to effectively process wood, metal and any other material of interest.

An angle grinder, which is commonly called a grinder, is not intended for processing wooden products. Even with proper selection of working circles, such operations are unsafe for health. Manufacturers producing discs for wood grinder 125 refer to this aspect in operational conditions, but not all people pay attention to this warning.

Working discs for angle grinders

In modern industry for the grinder, several types of discs are provided:

1. Abrasive wheels, which are divided into grinding and cutting wheels, are quite fragile if they are not used for their intended purpose. The range of operations for which they are designed is performed perfectly.
2. Diamond-coated blades, which are used for processing building materials and hard rocks. Subdivided into solid and segmented. Segmented discs are more suitable for grinders for metal.
3. Working circles for circulars, which experts do not recommend using in the processing of wooden products. It is better to choose saw blades adapted for the grinder, which are also popularly called a milling cutter.
4. Chain discs for grinders. Although outwardly they resemble shots from horror films, they cope with wood operations. the best way. They consist of a circle, along the edges of which a chain is applied like on a chainsaw. High-quality steel allows you to perform various operations with lumber, or rather, milling, modeling, stripping and cutting holes in logs.

When choosing wood discs for a grinder, you need to pay attention to the following points:

• the diameter of the circles should not exceed the diameter for which the grinder is designed;
• select the main details should be only those that are allowed for manipulation with the tree;
• sometimes you have to remove the protective cover, which is unsafe.

Therefore, you should try to select only those working circles that are provided for these tools, taking into account the diameter of the grinder and the material. Experimenting with power tools at high speeds may result in injury.

The nuances of using each type of circle

Diamond wheels can be called universal because they are suitable for almost any material. For processing building stones and other hard rocks, this disc is ideal. But segmented diamond-coated wheels are not used for metal processing, and they will not cope with wood either. Lumber usually hides many surprises in the form of knots and structural heterogeneity.

Metal abrasive discs 125 may be used to cut through wood. But at the same time:

• the thickness of the material should not exceed 4 cm (and it will have to be cut on both sides);
• it is necessary to take a break regularly to check the circle;
• change it at the slightest sign that the part has led;
• change a worn disk in a timely manner.

And you should also be prepared for smoke and the smell of burnt wood. It can take more circles to process lumber than a steel plate.

The use of circular discs for an angle grinder 125 is dangerous to health and life. Although there are advisers on how to adapt a circle for a circular grinder, it is better to refuse such recommendations. If only because the speed of rotation on the angle grinder is higher, because of which there is a danger of breaking the circle and increased vibration of the power tool. Circular circles are very fragile, and during their use on the grinder, there is a possibility of injury from flying fragments.

In such cases, it is better to use a milling cutter for a circular saw. It is distinguished by the shape of the tooth and the presence of special expanders, which eliminates its jamming, minimizes the appearance of a kickback and the occurrence of vibration.

For processing lumber, it is best to use chain discs for wood. The tool steel used for their manufacture is able to withstand loads and not shatter into fragments.

The service life of such a circle with a chain is several times longer than that of a cutter, in addition, it can always be sharpened. But the price of chain discs for a wood grinder 125 or 230 exceeds 2 thousand rubles.

Safety first!

Convenience in the use of angle grinders in operations with wooden material overshadows safety.

However, you can minimize the risk by observing some conditions:

1. When working with a grinder, use safety glasses and overalls.
2. The protective cover must not be removed.
3. Do not use a defective wheel in work, as well as discs on which there are even the most minor defects.
4. When working with a grinder, you should hold the tool with both hands.
5. It is impossible to lay the grinder until the rotating part stops completely.
6. The cord from the tool should be at a distance from the working circle.
7. Refrain from planned actions with a grinder if you feel unwell and in a state of intoxication.
8. Use wheels that are strictly suitable for the diameter of the tool and designed to work with the selected material.

These rules will help to avoid unnecessary injury when using the grinder in woodworking.

When choosing working discs for a grinder when buying, you should remember that it is better to spend a significant amount once, but to purchase a circle with a chain for a long time. It will help to perform many operations when working with lumber, as well as raw logs.

If the wheel is needed for a one-time use, you can opt for a milling cutter. Such a disc can also be used in working with aerated concrete and other materials. The cost of the cutter is lower than the chain cutter, but also exceeds the price of the abrasive device.

The most extreme case is the purchase of a cutting abrasive disc. But you should be prepared for strict observance of safety precautions: there is no need to swallow smoke and “enjoy” the aroma of burnt wood. In any case, such savings can cause irreparable harm to health, as well as lead to additional costs.

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 coating;
• 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 often used to perform a smooth cut of the board. 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.

Helpful 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

In this case, the saw circle is made 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.

Via saw blade you can make a straight 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, 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.

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 versatile version of a cutting saw blade for wood for a 125 mm grinder, then it is recommended to purchase a product with beveled teeth.

Helpful information! Wheels that have straight teeth are best for working 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 works 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 of wood.

Peeling discs for wood, equipped with wire coils, are also used for brushing. This event allows you to give the wood an unusual look, to 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 on an industrial scale, this element 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 the grinding wheel is fixed. 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 consists of a large number of sandpaper petals, closely spaced to each other. If desired, you can select the desired paper grain, which allows you to process wooden materials varying degrees 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.

Helpful 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 an 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. grinding disc on a tree of this kind 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 at once grinding wheels on wood. 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.

Helpful information! Unlike petal nozzles, abrasive particles are fixed with Velcro on the surface of the disc, 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 using such discs is quite convenient. Sticky nozzles can be easily purchased on the construction market or ordered on the Internet. Choice desired grit 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 carried out after grinding, can be carried out using special felt wheels. These tips provide maximum smoothness. working surface which is difficult to achieve with other tools. A large number of speed angle grinder contributes to uniform polishing of 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.

Nozzles for wood processing differ in 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. Improper work with the 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.

Processing of 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 angle grinder must be equipped with a speed controller, which must be moved to the minimum position. While working with cutting discs for an angle grinder it is very important to observe 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 starting operation, you should study the technical features of 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.

If you are trying to understand whether it is possible to saw a tree with a grinder, then the answer to this question is unequivocal: it is possible. But many will not do this, because. too many injuries people get precisely from using the grinder as a saw for wood, which is correctly called an angle grinder.

First of all, this is caused by a rather high speed of its rotation, at which most saw blades just not calculated. But who pays attention to this when you need to do the work, and there seems to be a suitable tool at hand, and there is also a compensator ring for a saw blade for wood right size applied. Moreover, the protective cover is removed for the convenience of work, which is absolutely impossible to do.

But, we won’t talk about injuries, but we’ll talk about how and how you can process (including sawing) a tree with the help of an angle grinder, but first, about the difficulties of working with a grinder with wood.

Difficulties when working with a grinder

About the discrepancy between the turns of the grinder and circular saw we mentioned, but users who have angle grinders with speed control can say that this factor has been taken into account, and any saw blade for wood is suitable for their tool.

Of course, by setting the number of revolutions of the output shaft of the grinder, corresponding to that indicated on the marking of the saw blade, they significantly reduce the risk of injury during operation, but do not completely eliminate it. This is primarily due to the material itself, or rather its structure and heterogeneity.

Even in different places of the same trunk, the tree has different hardness, not to mention the inclusions of viscous resin, the possible presence of metal that ended up in the thickness of the wood: from pellets and bullets that fell into the tree during a hunt, to a wire ingrown into it, with which branches were tied. Do not forget about the knots that are present in almost all types of wood.

When meeting with the listed obstacles, the saw blade brakes sharply and the angle grinder, by inertia, simply pulls out of the hands, and when passing through a hard section, it rushes forward with a vengeance.

When meeting with metal, there is a high probability of chipping of a hard-alloy tooth, which can be captured by the next one and thrown out at the speed of a bullet. Well, if in the area of ​​​​action of the protective casing.

A person who decides to cut a tree is in even greater danger, because at the same time the grinder must be put on its side, from which the usual and comfortable grip changes, which means that the grip weakens.

Discs for grinders designed for cutting wood

1. Chain discs and cutters based on them.

Structurally, they are designed so that even when biting a chain similar in structure to saw chains for chainsaws, the base can rotate, so the tool will not be pulled out of the hands. These discs are primarily intended for outdoor processing wood: sawing cups in log cabin logs, removing bark, modeling, but you can also saw with them, especially with a size 230 disc, which costs a lot, but compensates for its cost with safe work.

2. Saw blades for wood with a small number of teeth.

Such discs indicate the maximum speed and should be selected based on the parameters of your tool. Such a large pitch between the teeth compensates for the high speed of the grinder and makes sawing much safer than working with standard saw blades, but metal in wood should also be wary. You can see their work in the video:

In addition to wood, they also cope with plastic and aerated concrete.

3. Tungsten carbide discs.

This is a novelty in the field of tools for angle grinders, which allows you to freely cut wood without fear of metal inclusions, operating at rotation speeds up to 12200 rpm. She is the only one who gives an absolutely positive answer to the question: is it possible to cut a tree with a grinder. You can see for yourself by watching a short video about the operation of this disk:

Needless to say, these discs cut more than just wood.

4. Other tool, more or less suitable for cutting or other wood processing with a grinder.

About all in order:

a) Rotarex manufactures discs for cutting wood. In terms of their performance, primarily safety, they are inferior to those listed above, but are clearly more suitable for sawing wood than circular discs;

b) cutters for wood intended for outdoor processing wood angle grinder, can also saw not thick wood;

c) disk-planer - a nozzle for an angle grinder.

d) a saw for creating wooden sculptures with a configuration of cutting elements vaguely resembling links of a saw chain, not quite intended for sawing, but will cope with it to some extent.

Bulgarian for grinding wood

But this work, incl. on wood, just for this tool. Only a small photo selection of nozzles for angle grinders for grinding is evidence of this.

• for rough grinding.

• the most common type of nozzles for grinding angle grinders, the purity depends on the size of the abrasive grain on the petals.

• the easiest way to change grinding wheels is to use a sticky base holder attachment, on which replaceable abrasive wheels with different grains or even polishing bristles are attached.

• polymer abrasive silicon carbide with nylon.

• sanding belt.

And instead of a conclusion. Can a grinder cut wood? Depending on what and depending on what. If you cut a thin dry branch, then there are practically no restrictions, and if you have to do more serious work, see above.
