Disc for angle grinder for wood. Choosing a wood disc for a grinder, grinding angle grinder. Abrasive coated discs

It's like a fairy tale about a unicorn, everyone has heard about it, but no one has seen it with their own eyes. The public of construction forums and authors of similar articles on the Internet is divided into two camps. The former say that in their life they sawed more than one cubic meter of wood with a grinder, the latter give strong arguments in favor of the fact that after such work you can miss your fingers or limbs, or even worse. Is there a disc for a wood grinder and if so, what does it look like and is it safe to work with it?

The author of this article kindly asks you not to consider this material as a guide to action. An angle grinder is not designed to work with wood, even those manufacturers that produce discs and cutters for wood write on their official websites that it is extremely unsafe to cut wood with a grinder. But we all know that people rarely think about their health in the first place.

Cutting with an abrasive disc

Yes, it’s possible to cut a tree with a metal disc, to be honest, I myself, working at a construction site, have done it more than once. What can be said? Well, firstly, the speed of work with this method is low. Secondly, the smell of burnt wood even on outdoors within a radius of 10 meters you are provided. And thirdly, the thickness of the sawn board should not exceed four centimeters. This is not to say that the abrasive disc is not a wood disc for a grinder, its main purpose is to cut metal. As for the pros, in my opinion it is: the absence of sawdust, and a smooth, even cut.

Circular saw blade and its improved analogue

The vast Internet is full of video materials on how to turn a disk for a circular or diamond disc on concrete in a disk for working with wood. You can argue for a long time about whether it is worth doing or not? Even without considering himself helluva lot smart person, I would not conduct such experiments. And that's why:

• a circular saw blade is not designed for high speeds, yes, it is carbide, but no less fragile. A single chipped tooth can pose a great danger to a person.
• the edges of the toothed disc are not smooth, crashing into a tree, the grinder will vibrate and crash into the branches of the workpiece. this operation may cause the operator to lose control of the tool.
• increased chance of a kickback

There is an adapted disc for a wood grinder on sale, the manufacturers claim that due to the shape of the tooth and special expanders that are on the cutting part of the disc, all of the above concerns about tool jamming disappear. One of the manufacturers is the company Rotarex, in its assortment you can find both grinding and cutting discs for grinders. Below is an image of a circular disc and a grinder disc from Rotarex, which is universal. They can cut not only wood, but also aerated concrete.

Chain disk for wood grinder

At first glance, it may seem that this is a device for a horror movie, but judging by the reviews of the owners, this disc is safer than the analogues presented above. It is a solid circle, along the edges of which there is a chain from a chainsaw, everything is made of high-quality tool steel. The main purpose of such a disk: milling, modeling, stripping wood from bark and cutting cups in a log for log cabins. It is also possible to cut with such a disk, given that the width of the cut will be about eight millimeters, since the thickness chain disc is six millimeters. Speaking of diameters, there are 125 and 230 discs for sale. The service life of such a disc will be many times longer than that of others, since it can always be sharpened with a file. The price for them ranges from two to three thousand rubles, and even more will come out with delivery from another region.

Remember safety!

Whatever disc you work with and whatever material you cut, you should always remember that compliance with safety regulations can save you not only health, but also life. And before you get started, read the following points:

• not work in state alcohol intoxication;
• when working, use safety glasses and overalls;
• never remove the protective cover;
• it is forbidden to use a defective cutting disc or a disc with some, even minor, defects;
• when working with a grinder, hold it with both hands;
• the electrical cord must be at a distance from the rotating disk;
• do not put the tool down until the blade comes to a complete stop.

There are a lot of ways to cut a tree, one of them is to make a cutting disc out of paper. How effective this is, of course, is up to you to judge, but note that this is one of the safest options.

The angle grinder (angle grinder), popularly known as the "grinder", is a professional universal device that is used for a variety of purposes. With it, you can carry out a lot of work: cutting, grinding, polishing, saw cut and processing of various raw materials. When choosing a suitable model, you must understand its design features, evaluate your financial capabilities, as well as consult with a specialist.

Due to the wide variety of existing models, the choice ideal solution could be a real disaster. In any case, the emphasis should be placed on the purpose of the proposed equipment. wooden structures need the appropriate grinding wheels for a wood grinder. The same applies to metal - it is processed only with suitable tools.

Varieties of grinding discs

Currently on sale big variety disks on a grinder, and it happens to a simple layman quite difficult to choose grinding wheel for grinders on wood. To understand in more detail existing types, it is necessary to divide the assortment into the following categories:

1. Abrasive wheels. Such a consumable is particularly versatile, so it allows you to carry out accurate and high-quality events with minimal resource consumption. In addition, there is the possibility of additional polishing. Due to these characteristics, abrasive-type tools are one of the best.
2. Circles with diamond-coated- are very popular. Segmented and solid type models are available on the market. Depending on this option, the scope may differ. Both solutions are able to provide accurate cutting of any materials with the highest density. Among them: stone, metal and concrete products.

The blades for the grinder may resemble most modern saws, but they are made of other alloys. Initially, such goods were considered rare, but now they have spread very widely. Perfect option- combination of carbide and tungsten.

Woodworking discs

If you intend to purchase a wood saw blade for a bolarka, be sure to study the basic principle of operation of such a device. What features should be considered when purchasing a disk for angle grinder on wood?

The first thing you should pay attention to is the different standard diameters. Most compact solution has a size of 115 millimeters. However, many experts prefer to buy a wood disc for a 125 mm grinder, which is explained by great practicality. In addition, it is angle grinders on the 125th circles that are in special demand not only among representatives professional areas but also among home craftsmen.

It is no secret that a material such as natural wood is a specific heterogeneous raw material, so for its processing it is necessary to use different circles. Use classic models for metal or concrete structures Absolutely forbidden. If this is not taken into account, the tool will simply fail or burn out.

When choosing suitable products for grinding, pay attention to the diameter of the installed shaft. Standard value equals 22.2 millimeters. Initially, there were several divisions, so the marking value remains quite large. At present, most standard models have a diameter of 125 × 22.2 mm.

And although the allowable size of the angle grinder is 230 millimeters, it is not advisable to give preference to such sizes for wood processing. When working with large products, you expose yourself to the risk of dangerous damage and injury. Ideal dimensions represented by the range 115x22.2 - 125x22.2 mm. Yes, and circles of class 125 are the most versatile, so they can be used to solve a wide range of production operations.

After careful study of the specifics grinding discs for a grinder on wood, you can proceed to the search suitable models, which will ensure the safest and most efficient processing of such a valuable material as natural wood.

Types of cutting wheels

When buying a cutting disc, take responsibility for choosing the “right” model and pay attention to a number of design indicators. Among them:

1. circle diameter.
2. depth of cut in wood.
3. features of the teeth (shape, number, frequency).

If you want to use a cutting disc, consider the following recommendations:

In order not to make a mistake with the choice suitable solution, pay attention to the following selection features sawing consumable tools.

1. It is necessary to choose rounded cutouts that are made strictly towards the shaft.
2. Optimal Thickness disk is 2 mm.
3. The depth of the cuts made sometimes reaches 20 millimeters.
4. The cutout may be empty, but in some cases it is filled with a composition of copper.

Necessary equipment

In many cases, working with materials involves carrying out polishing, grinding, as well as peeling procedures.

It's no secret that cutting wood is a very dangerous activity, but even an inexperienced worker can do sanding an array. The main thing is that he has the required equipment at his disposal. Enough to deal with basic principles forthcoming work, and everything will be successful.

In most cases, flap discs are used for peeling. After a thorough study of the specifics of the product, you can be sure of its functionality and effectiveness.

From the name you can understand what are the features and principle of operation consumable tool. His work zone may have a small amount of sandpaper petals. This structure may resemble fish scales. As for papers with a low roughness, they provide a soft polishing of elite woods.

The quality indicators and the degree of processing are determined by the grain size of the material, so polishing and grinding are performed taking into account the established requirements.

Despite the great popularity of petal models, you can use other expendable materials. For example, very good decision can become a sticky disk universal purpose. Most modern nozzles have the ability to quickly change Velcro. The cost of used sticky discs is much lower than the cost of whole flap discs, however low price characterizes a short service life. In any case, universal sticky models are effective both in processing and in grinding the most various materials which explains their great popularity.

Tool characteristics and work quality

Even if you have purchased the most expensive polishing and grinding equipment, this does not mean that the quality of work will be maximum. What is it connected with? It's very simple: for successful processing, you must use exclusively dried wood. Raw material is unsuitable for this kind of activities. If this feature is not taken into account, the result obtained may not be the most pleasant. When choosing a wood disc, make sure that the selected raw material matches established requirements and standards.

In some cases, it becomes necessary to carry out cleaning work to remove the old layer of paint, varnish or fungal formations. good polishing and grinding tools always work the best way, however, provided that the material is prepared taking into account the basic technological requirements. You must understand that polishing and grinding discs for angle grinders are not suitable for primary processing operations, so they must be equipped with additional peeling nozzles.

When choosing the right nozzle, you will be able to feel their effectiveness in those cases where you need to carry out cleaning old surfaces which are covered with several layers of paint. This result is explained very simply: most nozzles are a kind of metal plate, on which there is a wire bristle, placed closer to the outer circumference in a radial or perpendicular manner to the disk.

Finishing actions are started in those cases when the workpiece takes on a preliminary shape. The end result can be determined by the types of nozzles that are used in solving the problem.

An angle grinder can also be used as a cutter, as well as grinding and polishing machines. The expansion of functionality is provided by the use of different types disks.

And so, if you are faced with the question: “how to successfully polish or sand a wood structure”, be prepared to take a responsible approach to studying the basic subtleties and recommendations. As for the tools that will be applied in the future, they include:

If you intend to choose the right equipment for the grinder, consider not only the diameter, but also many other markings. With the help of inscriptions, you can clarify the exact purpose of the tool and select the best option for your purposes.

Modern Bulgarian is one of the most convenient and useful devices. To improve the quality of its work, it is necessary to take care of additional nozzles and discs that will make the processing of wood, metal, or any other raw material accurate and complete.

The Bulgarian is associated with an ordinary user with a tool for metal, concrete, brick. This is not the whole area where angle grinders are used. She can work with wood. There are special discs for the grinder. For sawing, milling, grinding wooden blanks, several types of cutting wheels are used. Each is designed to perform a narrow-profile task. Universal variant does not exist.

Saw blades are classified by diameter. This parameter is taken into account when selecting a nozzle for a specific model of an angle grinder. If the disc diameter is greater than the allowable one, then working with the tool is possible only after removing the protective cover, and this gross violation safety regulations. To avoid problems, cutting wheels Available in several unified sizes:

• 115 mm - sanding wood in hard to reach places
• 125 mm - milling, grinding, debark
• 150 mm - sawing boards
• 180 mm - sawing thick boards
• 230 mm - processing of massive workpieces. An angle grinder with a disk of this diameter is difficult to hold in your hands

Depending on the design, the wood grinder disc is used in several operations:

• cutting
• Cleanup
• Milling
• Grinding

Let's consider each in more detail, and also determine the nozzles for each type of work.

cutting

A wood grinder disc is rarely used directly in sawing. With it, you can process boards up to 40 mm thick, while observing safety regulations. There are two types saw blades, with which you can cut the board:

• Hybrid. It consists of a round metal base and a chain around it from a chainsaw. The nozzle is used when working with thin boards, with small cuts along the length.
• Disc for circular or hand saw. This is a round saw element with teeth of different sizes located along its outer edge. The pitch and size of the tooth affect its characteristics. The larger it is, the more aggressive the sawing. The smaller, the neater the cut.

A standard circle for a circular or hand saw is cast from solid steel. It is designed for installation in a stationary machine with a hard seat. The angle grinder works at lower speeds, the disc constantly vibrates. This can lead to its destruction, as well as injury to the direct performer of the work and others. Therefore, this type of work is not always safe.

Cleanup

This is a rough job with wood, for which a wood grinder disc is suitable. There are two types of factory-made nozzles for this type of work.

• The disk is a planer. Practical attachment for the primary processing of logs and ends of irregular boards. It is massive, durable, equipped with three knives. With its help, the tree is cleared of bark. For work, it is not necessary to install a protective cover, since the thick cutting wheel will not collapse.
• Peeling. It consists of a metal base and a chain for a chainsaw, which trims its outer part. This structure allows you to perform a rough cleaning of wooden blanks from the bark, to even out cracks and chips. Peeling chain circle suitable for cutting wood.

Milling

Angular in progress grinder with wood attachments. Milling wheels cut grooves in the workpiece different widths. The size depends on the thickness of the nozzle. A perfectly even cut, like on a machine, is over. But cutting out a simple landing socket or groove for a tongue will not be a particular problem.

There are solid and compound nozzles for milling. Compound circles make a wider cut.

Grinding

This is a finishing treatment of wood, designed to remove small bumps and roughness. There are several types of nozzles:

• Cord brush. The working surface of the relief structure for deep, rough processing of wood. Cordbrush "bites" into the base, smoothing out bumps and chips.
• End disk. Shaped like a bowl. Work surface - only a narrow strip with outside saw circle. This shape allows you to process end angle cuts, as well as hard-to-reach areas.
• Petal nozzles for grinding. The most common type for finishing. It consists of a steel base glued with abrasive material. The depth and quality of sanding depends on the grain size of the sandpaper. The smaller it is, the smoother the surface will be at the output.

There are two versions. The first is a disk glued with pieces of sandpaper in the shape of a trapezoid. Each next petal is overlapped. With such a working surface it is effective to process wood. She is slowly fading away. Second - petal disk, where the abrasive material is located radially. Suitable for processing workpieces in hard-to-reach places.

• Velcro grinding wheel. It is designed for repeated use. Only changes working surface from sandpaper, which is attached to the base with Velcro. Sold in stores sandpaper With different size grains. This allows you to use the nozzle, both for rough and fine grinding.

Rules for working with angle grinders

• Work is carried out only in protective glasses and gloves. During coarse cleaning wood is better to cover the whole face.
• It is forbidden to remove the protective cover from the angle grinder.
• Work is done by holding the tool with both hands.
• Do not use a saw blade larger diameter than indicated in technical documentation to the instrument.
• While working with the tool, it is recommended to lean on both feet.

Firms - manufacturers

There are budget cutting wheels Hitachi, Makita, Luga. They grind faster, vibrate more than more expensive ones. The quality of the surface treatment differs from the result of more expensive analogues. Professionals choose saw blades Kronenflex by Klingspor or Bosch. They grind more slowly, practically do not vibrate. Less likely to be destroyed by improper use.

An angle grinder, a power tool familiar in working with metal, is also effectively used for processing other materials. Many people put a wood disc on the grinder without thinking about safety.

Is it possible to cut a tree with such a disc and what types auxiliary tool there are Bulgarians, let's figure it out.

There are special wood cutting discs designed for this job, but this is rather an exception. In addition, such a disk is not suitable for every angle grinder.
Let's consider several options.

Saw blades, blade and chain hybrid for chainsaws

These cutting discs can be used to cut boards up to 40 mm thick, with extreme care. Rules, non-observance of which lead to injuries:

The saw blade has metal base and a chainsaw chain fixed around the perimeter

1. It is strictly forbidden to remove the protective cover if the diameter of the disc exceeds the dimensions of the casing - your angle grinder cannot be used.
2. The angle grinder must run at the RPM indicated on the disc. Otherwise, the chain may jump off and its components may fly apart.
3. Safety goggles and thick gloves are required. It also does not hurt to wear thick canvas clothes.

IMPORTANT! It is strictly forbidden to use ordinary circular saw blades on an angle grinder.

The same applies to diamond cutting discs on concrete. For cutting work wooden products they are useless and dangerous. Firstly, the work efficiency is extremely low, especially considering the cost of the disk. Secondly, you can simply burn the workpiece.

And finally - such a disc can jam in the cut at any moment, and you will get hit by the grinder's body. Here is an example of a disc for a grinder, with which you can saw a tree with extreme care.

The design of the circle provides protection against jamming with the help of side teeth that expand the width of the cut. The disk has a diameter of 115 mm, and its dimensions allow you to work without removing the protective cover.

The wood disc fits completely under the protective cover

Some homegrown "masters" fit standard circular saw blades under, the work is done with the protective cover removed. Most often, such experiments end tragically. The unfortunate master receives severe injuries, and a fatal outcome is also possible.

At the same time, the construction markets are full of offers of saws for a grinder for wood. Sellers will assure you that in the hands of a professional, the use of such a tool is completely safe. This statement is true as long as these very hands are safe and sound.

Many homely owners have home arsenal grinder - this is what the people call the angle grinder. And so, when it becomes necessary to work with a tree: cut boards, cut down branches on trees or prepare firewood; and there is no appropriate electric saw at hand: circular, jigsaw, chain, etc .; some savvy craftsmen say to themselves: “So what ?! After all, there is a Bulgarian! You can totally get by with it!" How right are such resourceful masters? .. This is exactly what our article is about.

Never put a saw blade on grinders!

This is not just the title of an article subtitle, it is a cry from the heart of all power tool sellers. Indeed, they very often come to them with the same request: “Give me a saw blade for a grinder so that the tree can be cut.” And they all unanimously answer in such cases: “They don’t cut wood with an angle grinder! And in general, by definition, it is impossible to put a saw blade on an angle grinder! Why is that? We contacted the developers with this question. cutting tool TM attack and they gave us a comprehensive answer on this topic.

Yes, an angle grinder (angle grinder) is a powerful tool and can easily cut and a simple board, and thick log, as long as the diameter of the saw blade is suitable. But cutting wood with a saw blade mounted on an angle grinder is, first of all, very traumatic, especially if the protective cover is removed from it. After all, the angle grinder has a very high rotation speed, which creates centrifugal force, which will significantly increase the load on the saw blade. In addition, a circular saw is structurally different from an abrasive wheel - it has teeth, and this circumstance leads to increased vibration, especially if you install saw blades for metal. As a result, such a load will significantly exceed the tensile strength of the circular saw blade, it can simply break during rotation. What this is fraught with, probably, it has already become clear to everyone. And in such a situation, nothing will save from injuries: neither the protective cover of the grinder, nor individual means cutter protection.

To prove the danger of such disk “castling”, all kinds of tests were carried out. Yes, and in life there were many cases when the "savvy" owner was left without arms or legs. And in 2011 there was unique case, when a certain “economic” Volgograd citizen decided to cut branches from a tree at his dacha with the help of an angle grinder and installed a circular saw blade on it. As a result, he was brought to the thoracic surgery department with a torn chest. Fortunately for the poor fellow, everything ended well.

Is it possible to install a circle from a grinder on a circular?

The question can be rephrased: can circular saw use as angle grinder? In principle, this is possible. If you install an abrasive or diamond blade on a circular saw, then there is no risk for the cutter in this case. However, the circular is very poorly adapted for such operation. Yes, when you need a smooth cut, the saw will do the job. better grinders, but its protection from dust is much worse than that of the latter. Both the cutter itself and the tool are swallowed up with dust - then it will take a long time to blow it through.

In addition, the rotation speed circular saw significantly lower than what is required for effective work circles from angle grinders. For example, if you install a diamond abrasive disc on a circular saw and try to cut ceramic granite with it, then the engine can easily burn out. And the circles themselves will wear out faster. After all, sawy and abrasive discs designed for different angular speeds.

And once again we repeat: do not use saw blades on the grinder! Better buy an inexpensive circular saw!
