Homemade wood disc for angle grinders. Grinder disc for wood: general characteristics and types. Cutting wheel. Grinding and roughing works. Grinder discs designed for cutting wood

Corner grinder(angle grinder)

Wide selection power tools on the Russian market are designed to facilitate different types self made. If in the professional sphere the purchase of specialized equipment is simply necessary, then in everyday life it is not always rational to spend money on an expensive tool, which after completing a certain job may not be useful at all. The most popular power tool is the angle grinder (angle grinder). The scope of its application is not limited to metal processing - grinding wood with a grinder is done using special attachments.

For those who don’t know “Is it possible to process wood with an angle grinder?” this article will be useful. To perform grinding and polishing wooden products or large array surfaces, you will need to purchase an appropriate nozzle - a circle. For Bulgarians different sizes nozzles are selected that are designed for a certain rotation speed. Special discs designed for wood processing must be carefully selected. The disk 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-made wheels that are suitable for a specific model of power tool.

Processing wood with an angle grinder

Coarse grinding discs for wood for angle grinders

There are several types of circles that differ in shape, material of manufacture and purpose. As a rule, wooden blank First, the surface must undergo rough processing, after which it undergoes finishing or final detailing of the coating with abrasive segments.

For such work, there is a special attachment on the grinder for sanding wood. The most popular are:

• Grinding circles. This type of sanding attachment on an angle grinder is best used to remove a layer of old paint. Suitable for varnished coating which cannot be removed manually. This could 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 available with different locations steel bristles. Depending on the desired effect, the bristles can be placed along the entire perimeter of the disc parallel to the tool or perpendicular to the segment - as in a regular brush.

• Cord brushes are a disc with a coarse abrasive coating designed for rough sanding and removing uneven surfaces on a wooden surface. By using of this instrument wood blank acquires final form. The work productivity is significantly higher compared to conventional hand tools.

• End discs. Nozzles are used when you need to level a product from the end. Miter cuts and edges of the workpiece require such processing. The technique is identical to a file, but the efficiency of the abrasive exceeds that of hand tools. When working with a segment, it is important to have skills, and then such a simple tool can completely replace a molding cutter in terms of edge processing.

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

When executing grinding work With an angle 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 sand wood with a grinder, attachments of a universal design and with a special gentle coating are used. Such machining intended for specific work:

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

This is the most common type of grinder attachment for sanding wood, which performs 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 its grain size. The size of the abrasive determines how quickly and efficiently the unevenness on the wooden surface will be removed.

The sanded coating at different stages of processing may remain slightly rough or be perfectly smooth without the slightest flaws or snags. The final result can be achieved by sequentially moving from abrasive discs with a coarse-grained fraction to segments for finer processing. Therefore, you will need several discs for a grinder for sanding wood, which will be changed in stages.

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

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

The main advantage of a grinder wheel for grinding wood is the quick replacement of a worn-out replacement disk: the entire procedure takes place without removing the main attachment, which is secured with a nut. First, you need to purchase a sticky attachment for grinding on an angle grinder, so that later you can replace the worn-out abrasive segment without any difficulties.

How to choose grinding attachments for an angle machine

Circles should be selected according to the main parameters:

• outer diameter (larger sizes speed up the processing process and increase service life);
• bore diameter (installation of the circle larger size to a smaller one is possible using a special adapter);
• thickness (the greater the thickness, the longer the segment will last);
• grain size (the fraction must correspond to the type of processing: coarse abrasive for rough work, and small - for soft processing and creating a finishing coating);
• segment type (special attachments are suitable for processing wooden surfaces).

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

What you need to know when working with an angle grinder

Update flooring(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 attachments. Therefore, it is not surprising that an angle grinder for polishing wood is a popular power tool among professionals and at home. But in order to choose the right tool for the job, you need to carefully examine the wooden surface for the presence of fungus, cracks and irregularities. A video is provided to help beginners who want to know “How to properly sand wood with a grinder.”

A grinding attachment must be selected for each angle grinder model; only in this case will safe performance of work and high-quality surface treatment be guaranteed. Before you start working with a grinder (sanding wood), you need to make sure that the disc is properly secured. Move corner machine on the surface you need to move smoothly and avoid 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 the wheel breaking, which can lead to injury).

Cost of wheels for woodworking

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

Name of cities	Price of wood attachments, rubles per unit
		Abrasive discs for soft sanding	Roughing (cleaning) wheels	End	Cord brushes
Moscow	from 70 to 900	from 35 to 14900	from 86 to 270	from 33 to 430	from 36 to 5400
Saint Petersburg	from 95 to 800	from 35 to 14900	from 86 to 270	from 33 to 430	from 36 to 5400
Chelyabinsk	from 262 to 820	from 35 to 14900	from 86 to 270	from 33 to 430	from 36 to 5400
Novosibirsk	from 100 to 760	from 35 to 9000	from 86 to 270	from 33 to 430	from 36 to 5400
Kaliningrad	from 57 to 660	from 35 to 9000	from 86 to 270	from 33 to 430	from 36 to 5400

Manual work requires the use of high-quality tools, and an angle grinder with attachments greatly facilitates the work and speeds up the process of processing a wooden surface.

Modern angle grinders, better known as grinders, are used for various technological processes during construction and renovation. When choosing a disc for an angle grinder for wood, you need to consider important features not only the tool, but also the processed objects. Typically, the device is used for cutting metal. However, a large number of different disks allows you to use it to solve other problems.

First you need to decide on the tool (grinder - the correct name is chain angle grinder) with which you plan to cut the wood. It is known that discs are manufactured according to standard sizes Bulgarians. The smallest diameter is 115 mm, but this tool is used in rare cases. The wide variety of power tools on the market are designed to make it easier various types manual labor. If when working in a professional field specialized equipment is simply necessary, then in everyday life it is not always rational to spend money on expensive hand tools.

To operate the machine with wood, you need a special drive. Abrasive, diamond, and carbide wheels are absolutely contraindicated for cutting. This will not help cope with the task, but rather will lead to destruction or overheating of the device.

When choosing woodworking universal accessories, you should know that there are not only cutting discs, but also grinding wheels. To clean the wood, use a circular saw blade. The working surface of such a device consists of several layers of sandpaper, which has varying degrees of roughness. The lower the roughness, the softer the grinding. Petal circles allow for polishing, which depends on the degree of detail.

Grinding wheels and a milling cutter for an angle grinder must be of high quality, which affects not only the quality of the work performed, but also the safety of the technician. Processing wet wood is prohibited, as the result of such manipulations can be unpredictable.

For roughing operations, which are often used as initial processing, special cleaning agents are used. They are necessary in order to remove a layer of paint from a painted surface.

To process with a grinder and a circular saw, you need specially designed attachments with which you can grind, polish and mill surfaces. The choice is up to the master.

You can use the following circles:

1. An abrasive wheel for wood, which is used for working on various surfaces. Depending on the thickness of the circle, it can be cut and polished.
2. The diamond wheel is designed for working with stone, concrete and other building materials. Such circles are divided into segmented and continuous. The first type, due to better performance and better cooling, provides improved performance. These discs can be used for small metal cutting.
3. Regular circle. It should be noted that it is not recommended to use it for sawing wood products without experience. If possible, it is better to use another tool.

If you need to remove a layer of paint from a wooden surface, you need to install an attachment on the grinder. There are many on sale various options. They all differ in shape, design and specific work that can be performed using this tool.

The next cutter, due to the fact that the tenons on it are installed on a plane, allows you to level wooden surfaces - for example, if two boards on the floor in the place of the final structure are on different heights. This defect is easily eliminated, and the boards are then in the same plane.

There are circles made of twisted wire or in the form of a disk with windings of wire clamped in the central part. In addition to this, the wheel is often used to modify wood, giving it a distressed appearance. If such an effect is applied to wide surfaces in a professional environment, it is better to use special manual machines with wide details.

For grinding surfaces there are special attachments consisting of a metal base on which an abrasive grinding ring is attached. The circle is screwed onto the angle grinder shaft and tightened with a special wrench. It is often equipped with an adapter for mounting in a drill holder or drilling machine.

To choose the right disc, first of all, you need to decide what material to work with.

Can be used:

1. Thin blades (1-1.6 mm) are best suited for cutting thin sheet metals, such as car bodies. When working with thicker corners, they can cut faster, but the risk of blade damage increases significantly. In this case, it is safer to use thicker discs.
2. Hard - most often used for active processing (cleaning) of welds after welding and gluing metal surfaces just before welding. They are used to remove (cut out) fasteners and protrusions on metal. They are also used in cases where the metal surface must be cleaned of rust or old paint.
3. Elastic - mainly used as an alternative to metal brushes. They perfectly clean even curved metal surfaces from outdated paint and other similar coatings.
4. Coarse - used for grinding metal and wood. Even the smallest welds can be smoothed out with large (largest grain) discs, but are mainly used for finer work. They remove faded top layer wooden surfaces, polished wooden beam, rust and outdated metal paint.
5. Abrasive - for processing concrete, diamond discs are slightly smaller, but they also have a shorter service life. Their use is justified only when it is necessary to perform a small one-time job.
6. Diamond blades are used for cutting various products made of concrete and stone (paving slabs, steps, curbs, facing stones), as well as bricks of all types.

Turbo diamond discs (both regular and wave) are best suited for working with reinforced concrete and stone materials. When choosing, keep in mind that a turbo will provide a cleaner cut than a diamond wheel.

If the appliance has an outer diameter of only 125mm and the grinder is rated for 115mm, it cannot be installed for the following reasons:

1. Firstly, the discrepancy between the revolutions of the tool itself and the circle is dangerous for the user.
2. Secondly, as it heats up and expands, the disc can get stuck, causing it to jerk.

The number of teeth is important. How less number, the faster the work will be, but the quality of the cut will be lower, and vice versa, a larger quantity increases the cutting time, but the ends of the resulting parts will be smooth.

With a large number of small teeth, the device will work with low efficiency. Large teeth allow you to work faster. The cost of the disc depends on the external size, number of teeth, and manufacturer. The most expensive model is with a circular saw.

For many reasons it is better to buy circles famous companies. The concept of a “quality disc” includes not only the degree of disc rupture and its abrasive properties, but also safety.

When choosing a new wheel, you should make sure that it is designed for speed. grinding machine. The permissible speed is indicated.

You need to follow the rule: the larger the rasp disk, the lower the speed. In addition, manufacturers protect the user as much as possible by releasing discs with high (sometimes double) strength. But if the disk is used more than necessary, all these measures become meaningless.

• work with protective casing;
• protect your face and head;
• check lumber for nails and screws;
• hold the device firmly by hand;
• use an additional handle (many people hold the device with one hand);
• Do not allow the instrument to heat up, avoiding the risk of smoke.

In addition, if there are no plans for large-scale work with an angle grinder, there is no need to buy a lot of disks “as a reserve” - since the humidity in the air begins to affect the bakelite. The bond strength is noticeably reduced. It is better to get the necessary wood discs for an angle grinder (grinder) immediately before work.

1. What types of cutting wheels are there?
2. Tips for work

An angle grinder, popularly known as an angle grinder, is a worthy and versatile tool. It is this equipment that allows you to successfully perform cutting, grinding, polishing, and sawing 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 of discs and a specific approach, otherwise the work will not bring the desired results.

Grinder wheels: starting with market research

The assortment is amazing in its diversity. What types of grinding discs are there 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, because with its help any workpiece can be cut and polished with high quality. In addition, the possibility of polishing is assumed. It is not for nothing that this abrasive tool is considered one of the best.
2. Diamond-coated grinder disc is one of the most common construction tools. These products can be segmented or solid, and each option has its own area of ​​use. In each case, the possibility of high-quality and accurate cutting of durable materials, including stone, metal, and concrete monolith, is assumed.
3. Saw blades for an angle grinder visually resemble modern models saws. However, other alloys are used to produce them. Previously, the product was rare, but now its prevalence is actively growing. Most best option disk for grinding machine made of tungsten carbide.

Taking into account the variety of modern products, you should abandon pointless and sometimes dangerous attempts to install a circle from a circular saw to an angle grinder. Any circular discs are designed for low speeds, and the grinder runs the risk of warping or destroying the tool.

How to choose a suitable angle grinder model?

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

Grinding wheels come in several standard diameters. The most compact model has a size of 115 mm. However, 125 mm grinder discs are of greater practical importance. Moreover, it is angle grinders for 125 laps that are most widely used not only among professionals, but among home craftsmen.

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

When choosing grinding equipment, it is important to note that standard diameter the installed shaft is 22.2 mm. Previously there were several divisions, so marking still plays a role 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. Preferable dimensions are 115x22.2-125x22.2 mm. In addition, 125 circles are capable of coping with a fairly wide range of production tasks.

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

What types of cutting wheels are there?

Parameters that are used for classification cutting discs on wood:

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

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

1. If cutting saw blades for an angle grinder on wood 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. Models with straight teeth are suitable for cutting coniferous and soft wood. Such saw blades successfully process even the softest wood, guaranteeing a decent work result.
3. Trapezoid tooth allows universal use. When choosing such equipment, it is best to cut medium-density wood chips. If desired, you can use other types of products.

What parameters should be taken into account for successful work with wood, when are saw consumables selected?

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. The cutouts are empty, but in some cases they are filled with copper.

Equipment for grinding and roughing work

In most cases, working with materials requires not only polishing, but also grinding and roughing activities.

Cutting wood is a dangerous activity. At the same time, anyone with the necessary equipment can grind the array. The most important thing is to understand the principles of performing technological operations.

Most often, petal discs on an angle grinder are used for peeling. By carefully studying the specifics of the product, you can 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 sandpaper petals. This structure is comparable to fish scales. At the same time, such low-roughness paper allows you to guarantee a soft sanding of natural wood. The quality and degree of processing depend on the grain size of the material, so polishing and grinding can be carried out in accordance with the requirements.

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

For example, sticky deserves attention universal disk. Modern attachments for grinders provide the ability to quickly change Velcro. The price of the adhesive discs used for basic operations is lower than that of a solid blade disc, but the service life is also shorter. If you still choose a universal adhesive wheel for an angle grinder, then it can be used for processing and grinding various materials, which confirms the demand for this product.

Polishing and grinding tools may be of high quality, but they cannot guarantee 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 should not be used. Otherwise the result will be unpredictable. When choosing a blade for wood, you need to be sure that the material being processed has the appropriate properties.

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

When choosing similar attachments for an angle grinder, you can feel the maximum benefit from them when cleaning old surfaces that have been painted many times. This is explained by the following factor: the nozzles are made in the form of a metal plate, which is densely studded with wire bristles located closer to the outer circumference, radially or perpendicular to the disk.

Tips for work

Finishing work begins only after the workpiece has been successfully given preliminary outlines. The results largely depend on what types of attachments are used to perform the assigned tasks.

Angle grinders are used as a cutter, as well as polishing and grinding devices. Attachments for an angle grinder increase the functionality of the device used.

So, how to carry out the polishing and sanding process when processing wood? What tools are needed for successful work?

1. Brush cord. These tools are ideal for rough sanding of wood. The possibility of successful leveling of wood is assumed, with the addition optimal shape product.
2. End discs make it easy to grind workpieces. In most cases, such work is required for miter cuts. Job end disc resembles the interaction of the workpiece with the saw.
3. Petalaceae grinding attachments- This is the most popular option for consumables used. The characteristics of the tool determine the ability to process various workpieces, including natural wood. It is important to note that cleaning of complex wooden objects is carried out only using radial strips.
4. Felt wheel - allows you to achieve minimal roughness in processed products. The basis is compressed wool, fine-haired, semi-coarse-haired and coarse-haired. A felt working tool allows you 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 grinder wheel intended for grinding is often compared to a disc of the same name. It is important to note that the Velcro circle is universal tool, having a wide scope of application. Various wood processing devices perform specific tasks, but the grinding wheel sometimes surprises with its versatility and high level efficiency.
6. A chain disk for wood is one of the most productive, but crude methods of processing natural material.

When choosing equipment, it is advisable 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 attachments for an angle grinder is a guarantee of a successful result.

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

A grinder, or angle grinder, is a tool that has no analogues in its popularity. If initially the scope of its application was limited to the operations that determined the name of the unit (grinding and technologically similar types of material processing), then gradually the range of application of this power tool and the replacement attachments produced for it expanded incredibly. Now they use a grinder to cut metal and polish it various surfaces, clean from dirt and old paint and much more.

The presence of a rotating rod made it possible to adapt the grinder for sawing wood. They began to try to install saw blades produced for circular saws on it. Manufacturers of attachments for this tool responded by developing and producing special wheels, similar in action to circular saw blades, but adapted to the high speeds and increased safety requirements of hand tools.

Features of using an angle grinder on wood

Sawing wood using hand tools involves a number of features. Wood is a heterogeneous natural material; its density is unevenly distributed. After a relatively loose area, a denser one may suddenly begin; there may be defects hidden in the thickness that were once filled with resin during the growth of the tree. There may be developed or underdeveloped knots, and sometimes ingrown foreign inclusions (nails, wire, shot or even bullets that hit the tree in the forest, for example, during a hunt).

Thus, it can be almost impossible to unambiguously select the operating mode of a cutting hand tool. This can lead to jerks, the energy of which will have to be extinguished with the help of hands; in special cases, the instrument may even break out. If a cutting tooth hits metal, it can be broken and thrown out by the next tooth with enough speed to cause serious injury.

Unlike circular saws (stationary or mobile), the grinder has a higher number of revolutions on the pulley, this is necessary to perform its main function - grinding.

When adapting this tool for sawing wood, craftsmen often removed the protective casing, which is categorically unacceptable, given the above-mentioned features of wood, such as natural material with unpredictable variations in properties. If the need to use an angle grinder as a circular saw still arises, in order to ensure safety and get the greatest effect, you need to purchase a special disc designed specifically for this tool.

Saw blades for angle grinders

Wood saw blades for angle grinders were developed various manufacturers and, accordingly, have several varieties. The simplest and definitely the most budget option is to install a circular saw disc of appropriate sizes on the grinder - both the outer diameter and the inner diameter mounting hole. For an angle grinder, which according to its size characteristics is classified as small, a circle measuring 125x22 mm is suitable.

Technically, you can install a disk with a diameter of 230 mm on a small grinder, but to do this you will have to remove the protective cover, which is absolutely unacceptable. The angle grinder user's hands are in close proximity to rotating working surfaces and any emergency situation can cause serious injury. Using such a wheel on an angle grinder can cause serious safety violations and is strictly not recommended for beginners.

Any distortion, including those associated with the unevenness of the wood structure, can cause jamming of the disk and, as a result, a sharp jump in the entire unit, to the point where it can break out of your hands and make a dangerous, unpredictable flight. The circular saw blade is not designed for such fast speeds as the angle grinder spindle produces; this causes excessive heating, which affects the strength of the steel. As a result, if the saw wheel is misaligned, it may collapse with fragments scattering at high speed in unpredictable directions.

Special attachments for sawing wood, developed for UMS, have significant differences from the circular saw blade. Let's look at the most common options for sawing wood. On sale you can find saw blades similar to circular saws, which have an increased tooth spread, which significantly reduces the likelihood of them jamming. In addition, the difference in the manufacture of such a disk is that other alloys are used, this reduces the risk of destruction of the disk when it is heated.

Further attempts to protect the blade from jamming led to the combination of a circular saw and a chain saw in one product. A chain similar to a chainsaw chain moves freely along the working surface of the disk, which absolutely eliminates jamming. There are quite a few modifications of this hybrid. Craftsmen using such a combination saw successfully cut branches and can even cut not very thick trees.

Another direction in adapting circular saws for use on an angle grinder was reducing the number of teeth. Discs with a diameter of 115 mm or 125 mm are equipped with only three teeth; a disc for a large 230 mm grinder can have 4 teeth. In this way, manufacturers tried to compensate for the high rotation speed of the saw blade.

A completely new direction of evolution circular disks was marked by the invention special nozzle, which is suitable for work on various materials. This universal disc is made from a special composition - tungsten carbide. There are no teeth on such a saw blade at all. This type of disc allows you to cut the most different materials, it can be considered the most secure disk for sawing wood of all types that are used on angle grinders.

Sawing with a grinder

If there is no other way out, that is, a special wood saw is missing (broken) or urgent small work is required, of course, a grinder can help out. However, we must remember that the main purpose of this machine is not to cut wood. For use of angle grinders As a hand-held circular saw, you will need to stock up on one or more specialized attachments.

To avoid distortions and jamming, you need to saw in a comfortable position and fix the tool with both hands. The best results can be obtained if you do not remove the special guide handle; with its help it is much easier to control the angle grinder. Correctly sawing off a workpiece using a grinder is not at all easy; due to the heterogeneity of the wood, the operating mode will constantly change. Therefore, while working, it is better not to be distracted and monitor how the cut is progressing.

If you need to use a grinder to cut wood, it is better to use a circle with a small diameter of 115 or 125 mm. 230th circles are much more dangerous, they have greater inertia, and in the event of an emergency it is not possible to stop their rotation immediately. Installing the saw blade on the angle grinder\. you need to take into account the direction of rotation, it is often indicated on the disk itself in the form of arrows. The teeth of the circular saw have special soldering that increases their performance. It will be difficult to cut a disc installed in reverse. When purchasing saw blades for an angle grinder, you need to pay attention to the following parameters:

• saw diameter;
• required depth of cut;
• shape and number of teeth.

If you plan to cut wood infrequently, then it is better to choose a saw wheel with teeth that have a variable set. If the main material on which you intend to work is chipboard, it is better not to use a saw with a large number of teeth. If the grinder will be used in the construction of a log structure, it is better to purchase a chain circular saw. Sawing boards will require paying attention to the depth of cut and the diameter of the blade.

Circular saw It will last longer if teeth that become dull during work are sharpened, it is better to entrust this to a specialist. In order to sharpen the saw, the same grinder can be used only with a special abrasive attachment. You will also need a stationary vice for this operation.

The modern grinder is often used to perform various works in the process of renovation and construction. Such a tool can be called universal. The grinder easily cuts almost any object, grinds, sharpens, polishes and peels. To perform work using an angle grinder, it is necessary to select the right discs, taking into account the type of tool.

Grinder wheels for wood

An angle grinder (grinder) performs a wide range of different operations using rotational movements of replaceable discs or attachments. The most commonly used circles are metal, stone, and wood. All of them are divided into three main groups:

1. Cut-off
2. Grinding (cleaning)
3. Grinding (grinding)

Each group has its own types of discs, which are designed for a specific type of work, including wood.

Woodworking discs look like a regular circular saw; you need to know how to work with them, since careless movements or inattention can lead to serious injuries. The protective casing on the disk serves as good protection, so it is better not to remove it from the tool and, for your own safety, use a wheel with fine teeth. According to experts, it is best to work with wood attachments without strong feed and try to secure the grinder permanently, using a special device for this.

The most common ones can be called wood circles - cutters, they look like metal circles with teeth and are specially designed for cutting wood. The circles can be different in size; depending on the thickness of the timber, the diameter of the cutter is selected.

For cutting wood, only saw blades and right choice provides a wide range of possibilities. If you know how to use the tool, you can even cut at an angle.

Disc production

Saw blades for grinders on wood come in two types - monolithic and with carbide tips at the ends of the teeth. If there are such soldering on a saw blade, then they wear out less quickly, do not require wiring, and perform better cuts, but they need to be sharpened only on special machines.

For the production of saw blades, only carbide sheet steel. It guarantees the product high resistance to mechanical damage and temperature changes. During the production process of the saw wheel, much attention is paid to the weld, it connects the body of the disc with the teeth, so its quality is always under control.

The speed and frequency of cutting is influenced by the number of teeth on the wheel; the higher the frequency of the teeth, the better the quality of wood cutting, but at the same time the speed of work decreases. When there are fewer teeth on the cutter, the speed increases, but the cleanliness of the cut deteriorates.

Impact of disc teeth

The final result of working with wood depends not only on the frequency of the teeth, but also on their shape. Universal saw blades can be called variable tooth cutters, they work well on hard and soft woods. Products with trapezoidal teeth are only suitable for working with soft materials. For draft Wheels with straight teeth are suitable.

During processing valuable species For wood, you need to use thin saw blades; they are great for cutting or processing expensive wood.
