Bulgarian, or angular Grinder(angle grinder), is a very popular tool that is versatile. It is used in the process of performing most construction work. Many people are interested in the question of whether it is possible to cut a tree with it. To process this material, it is necessary to choose the right wood disc for the grinder. There are many varieties of nozzles, differing in characteristics and purpose.
The range of nozzles for this tool is quite wide. Products are classified according to their purpose, depending on which 3 main groups of circles for angle grinders can be distinguished:
- saw;
- with diamond-coated;
- abrasive.
Saw. They are similar to standard saws, but are made from other materials. The most common option is tungsten carbide discs. They are not suitable for woodworking.
Diamond coated. This group of circles for the grinder is the most extensive. The high popularity of diamond-coated nozzles is due to a wide operational spectrum. With the help of such circles, it is possible to carry out processing metal parts, as well as stone and concrete elements. For a tree, such disks are not used.
Note! The use of angle grinders requires compliance with certain rules. One of them claims that it is impossible to use circles of a larger diameter than indicated in the device's passport.
Abrasive. They are highly versatile. Abrasive discs are used not only for cutting, but also for grinding and polishing surfaces. Products from this group are also used for wood processing.
These products are differentiated by one more sign - dimensions. The modern market provides wide selection products, the dimensions of which vary from 115 to 230 mm. The 115 mm wood grinder disc is the most compact and is used for fast and accurate cutting of material. It is worth noting that the largest discs are not suitable for working with wooden surfaces.
Types of wood discs for angle grinders: design options
Many experts do not recommend using a grinder for cutting and processing wood. This is due to the principle of operation of the device and the characteristics of the material itself. However, the variety of discs for angle grinders is growing every year. They can be divided according to the features of the work into several types.
Circular saws. Such wood circles for grinders are used, as a rule, for more technologically advanced equipment, but many install them on angle grinders. They are divided into two types: large diameter soldered and more compact, without soldering.
Chain. Ideal for working with wood materials. Many people are interested in the question of whether it is possible to saw a tree with a grinder. There is no single answer to it, however, chain products are maximally adapted for this purpose. The edge of the circle in this case is equipped with a chain on which the teeth are located. Such a design has many advantages. This nozzle is most commonly used for smooth cutting boards. With it, you can process other materials: chipboard, fiberboard, plywood.
Saws with a small number of teeth. This kind of circles was invented specifically in order to ensure maximum human safety when working with wood. Compact products belonging to this group have 3 teeth, and larger ones - 4. This group also includes cutting discs for a 125 mm wood grinder. These products do their job well. They can be used to cut wood along and across the grain. In addition to standard functions, such discs are used to organize grooves in workpieces.
Segmental (material - tungsten carbide). Such products appeared relatively recently, but have already gained immense popularity. A distinctive feature of such products is 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
AT this case the saw circle is performed using a chain from a chainsaw. Such a nozzle is the most suitable for working with wood, as it has the highest efficiency. chain disc on wood for the 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. The functionality of chain products allows them to be used as peeling tools. They do an excellent job of removing the bark.
With the help of a saw blade, you can make an even cut parquet board, plywood, fiberboard, chipboard, as well as ordinary unedged and edged wooden products. It is important to remember that the thickness of the material to be processed with such a nozzle should be no more than 4 cm. Otherwise, the device is likely to overheat.
Cutting disc for wood for a grinder: features
For the manufacture of such products are used special material- tungsten carbide. This is explained by the following: when working with a grinder, there is a possibility that it will break out of your hands, so the material of the circle must have high strength characteristics. The use of tungsten carbide can significantly increase the safety of work, but the cost of such products is quite high.
Discs of 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 nozzle for a particular situation. The shape and frequency of the teeth also play a very important role. The most common wheel size for working with wood is 125 mm. If you decide to choose the most universal option cutting saw blade for wood for a 125 mm grinder, then it is recommended to purchase a product with beveled teeth.
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 a grinder of this type have some design features that are determined by their purpose. For example, during operation, products easily overheat, so they have special slots that can be empty or filled with copper. Such a measure allows you to compensate for the thermal expansion of the metal that occurs at high speeds. The width of such slots can be different, but not more than 2 mm. As for their depth, it does not exceed 20 mm.
Grinding disk for wood for a grinder: characteristics
With the help of a grinder, you can not only cut and saw off wooden parts, but also carry out peeling work of varying degrees of complexity. The modern market offers a wide range of such nozzles. They are classified according to several indicators: form, design and purpose.
Peeling wheels are used to remove bark from logs or boards. Thanks to them, you can easily remove the excess part of the tree from the end surface of the board. They may have special spikes or crumbs.
Peeling discs for wood for grinders are also used to level the surface of the boards. Such circles are equipped with special spikes, which are placed on a flat plane. This feature is very useful, as it allows you to polish the boards from which the flooring is constructed.
On sale you can find peeling products consisting of twisted wire. They are usually called korshchekami. Such attachments for a grinder for woodworking are of two types, depending on the features of their structure. The first option provides for the presence of a base in the form of a glass to which the wire is attached. The second type is a disk with a wire fixed along the edge.
Brushes are used to eliminate paintwork materials with wooden surfaces. It is important to note that most often such nozzles are used to remove paint and rust from metal pipes.
Note! For wooden parts, it is necessary to choose a thinner wire that will not damage the workpiece itself. These products are suitable for different types wood.
Peeling discs for wood, equipped with wire coils, are also used for brushing. This event allows you to give wood unusual view, artificially age it. However, with the help of a grinder with a peeling wire nozzle, only small volumes of wood can be processed. Thus, for brushing on an industrial scale, this element is not recommended.
Grinding and polishing discs for wood on a grinder
Grinding and polishing of wood is carried out using special nozzles that are used for grinders. Such products include a metal base on which is fixed grinding wheel. Fastening is usually done with Velcro.

To use such a wood attachment for a grinder, it is necessary to fix it with a key (open-end) on the tool shaft. Quite often, it is implemented complete with a special transition element, thanks to which it becomes possible to quickly attach to the drill chuck. In turn, polishing requires the use of a more gentle material. Therefore, nozzles of this type are equipped with felt discs. Their fixation is also carried out with Velcro.
Another option for a grinding wheel for a grinder is a petal one. Its design fully justifies its name. It is made up of many petals. sandpaper, located close to each other. If desired, you can select the desired paper grain, which allows you to process wood materials of varying degrees of density.
Although 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, it is produced rough grinding, 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, there is the possibility of selecting the right tool, corresponding to a particular grinding option.
Helpful information! For rough processing, a larger diameter wire is used.
end discs for grinding wood on a grinder, they are used when it is necessary to adjust the size of the part from the end. Often, such products are used for the usual alignment of the side surface with uneven cuts. The principle of operation of the end nozzle resembles the operation of a file. The difference in this case lies in the high efficiency of the angle grinder.
The use of grinding attachments greatly simplifies the processing of wooden blanks. Such products allow for the restoration old furniture, removing paints and varnishes from its surface.
Grinding discs for grinders: flap discs
After rough processing, it may be necessary fine finish. Of course, if the wood is to be further painted, there is no need to bring its surface to a perfectly smooth state. However, in most cases, finishing is necessary action. To perform grinding, you can use a common nozzle - a petal circle.
The design of the petal disc model, as mentioned above, includes sheets of sandpaper that have a trapezoidal shape. Their grain size is selected depending on the type of wood and the specifics of the work. This type of wood sanding disc is one of the most common. It ensures gentle handling of the material and is characterized by a high degree of safety. It is almost impossible to get injured using this disc.
The size of the abrasive coating on the petals determines the efficiency and speed of wood processing, as well as its appearance. For maximum smoothness, it is customary to use fine-grained products. Experts recommend using several of these grinding wheels on wood at once. This will enable you to quickly rough cleaning, then finish the work with soft petals, bringing the workpiece to the desired degree of smoothness.
The use of such a nozzle requires a certain skill from a person. Therefore, before using the petal circle, it is recommended to practice on wooden parts.
Grinding wheel for grinders: soft processing and polishing
For soft grinding, special discs are used, which appeared on the market not so long ago - just a few years ago. Such circles are characterized by a high degree of functionality and can have different grain sizes.
Helpful information! Unlike petal nozzles abrasive particles are fixed with Velcro on the surface of the disc, and not on its end part.
Grinding disc for wood grinder of this type has one advantage - ease of replacement. This procedure is performed without removing or disassembling the main nozzle, so using such discs is quite convenient. Sticky nozzles can be easily purchased on the construction market or ordered on the Internet. Choice desired grain size in this case is not a problem. With the help of such devices, you can bring the wooden surface to the desired state.
Polishing, which is 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.
Woodworking attachments are different high efficiency and quality. Sequential use of these disks allows you to achieve incredible results. The wood surface after their use can be compared with a mirror.
Safety rules when working with a wood grinder
The use of angle grinders for wood processing requires a serious approach. 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.
Treatment wood material with the use of angle grinders must be carried out with protective gloves. Sawing and cutting discs for wood are best used on medium (in terms of power) devices. This is explained quite simply: if the saw jams, then you have a high chance of holding the tool in your hands. With a powerful device, this will be much more difficult.
For sawing logs and boards, it is recommended to use nozzles that have fine teeth. The smaller their dimensions, the less effort will be required to cut. Among other things, it reduces the likelihood that hard wood fibers will meet in the path of the disc.
Any Bulgarian without fail must be equipped with a speed regulator, which must be moved to the minimum position. When working with cutoffs, it is very important to maintain a right angle. Otherwise, the cutting process will be uneven, and the device itself may jam.
Angle grinder can be used for wood processing, however, before use, you should study technical features various nozzles. Products that are used for grinding and polishing do not carry any danger and are easy to use. Blades for sawing wood material require careful selection. During operation, it is necessary to observe the safety regulations and not deviate from them.
The modern grinder is often used to perform various works in the process of repair, construction. Such a tool can be called universal. The grinder easily cuts almost any object, grinds, sharpens, polishes and peels. To do the work with the help of a grinder, it is qualitatively necessary to select the right discs, taking into account the type of tool.
Discs for grinders on wood
Angle grinder (grinder) performs a wide range of different operations rotational movements interchangeable disks or nozzles. The most commonly used circles for metal, stone, wood. All of them are divided into three main groups:
- Cut-off
- Sharpening (cleaning)
- Grinding (roughing)
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 wheel, you need to know how to work with them, because careless movements or inattention can lead to serious injuries. The protective cover on the disc serves as a 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 nozzles without a strong feed and try to permanently fix the angle grinder using a special device for this.
The most common can be circles on wood - milling cutters, they look like metal circles with teeth, they are specially made for cutting wood. Circles can be different in size, depending on the thickness of the timber, the diameter of the cutter is selected.
For sawing wood, only saw blades and right choice gives a wide range of possibilities. If you know how to use the tool, you can even make cutting at an angle.
Disc production
There are two types of saw blades for a grinder on wood - monolithic and with carbide soldering at the ends of the teeth. If there are such solderings on the saw blade, then they do not wear out so quickly, they do not require wiring, they cut better, 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 fluctuations. In the production process of the saw blade, great attention is paid to the weld, it connects the body of the blade with the teeth, so its quality is always under control.
The speed and frequency of cutting is affected by the number of teeth on the wheel, the greater the frequency of the teeth, the better the cutting of wood will be, 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.
Influence of disc teeth
The end 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 milling cutters with variable teeth, they work well with hard and soft woods. Products with trapezoidal teeth are only suitable for working with soft materials. For draft version fit circles with straight teeth.
When processing precious woods, you need to use thin saw blades, they are great for sawing or processing expensive wood. There are also "thin +" discs, where material is used with an additional chipper, it reduces blocking of the saw during its operation. This saw blade is suitable for longitudinal and cross cutting of wood and other materials. Similar materials from high precision cuts are also used in furniture and woodworking industries.
Features in working with saw blades
When working with a saw blade for wood, special care and skill must be exercised, it is best to put on a special uniform and goggles and gloves. The complexity of working with wood lies in the fact that the tree is easier to cut, so it is necessary to observe control in the operation of the tool. Experts recommend using a tool of low power and speed when working with wood, the most best option- 1,000 rpm.
Equally important is the quality of the grinder, as well as the cutter, the final result of the work and its safety will depend on this. It is best to give preference to a proven tool, to hear the opinion of experts in order to be sure of a positive result.
grinding wheels
For execution various works with the help of grinders are made grinding and polishing wheels, They may be:
- spongy
- Felt
- With replaceable sandpaper
- Cloth
The material is selected depending on the surface to be sanded. To process wood species, petal grinding wheels are used, they are made of sandpaper, which is fixed on a rigid frame. Sandpaper can be coarse and fine grit, the markings can be seen on the product itself.
If planned make wood smooth, then it is best to use a fine grit wheel, to remove a small layer of wood - medium grit. If you need to remove old paint, then you need to apply a coarse-grained circle.
According to their design, grinding wheels can be petal, movable and solid. Flap wheels give the smoothest surface to wood, therefore they are used as finishing circles.
Conclusion
When working with an angle grinder, you must always follow safety precautions. It is good when the tool is equipped with a persistent handle and a protective cover. Devices are considered safe, in the edge of which there is a chain from a chainsaw, it is specially installed there. In the event that one of the teeth is jammed, the disc rotates idle, and this reduces the risk of injury.
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:
- 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.
- Diamond coated discs that are used for processing building materials and hard rocks. Subdivided into solid and segmented. Segmented discs are more suitable for grinders for metal.
- 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.
- 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 jamming, minimizes the appearance of a reverse impact 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:
- When working with a grinder, use safety glasses and overalls.
- The protective cover must not be removed.
- Do not use a defective wheel in work, as well as discs on which there are even the most minor defects.
- When working with a grinder, you should hold the tool with both hands.
- It is impossible to lay the grinder until the rotating part stops completely.
- The cord from the tool should be at a distance from the working circle.
- Refrain from planned actions with a grinder if you feel unwell and in a state of intoxication.
- 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.
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, a wide variety of discs for an angle grinder is offered for sale, and it happens to a simple layman it’s not at all easy to choose a grinding wheel for a wood grinder. To understand in more detail existing types, it is necessary to divide the assortment into the following categories:
- Abrasive wheels. Such consumables are 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.
- Circles with a diamond dusting - enjoy very wide popularity. 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. The ideal option is a 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. It is strictly forbidden to use classic models for metal or concrete structures. 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 125x22.2mm.
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 sizes are 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 a thorough study of the specifics of the grinding discs for the 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:
- circle diameter.
- depth of cut in wood.
- features of the teeth (shape, number, frequency).
If you wish to use cutting disc also consider these recommendations:
In order not to make a mistake with the choice suitable solution, pay attention to the following selection features sawing consumable tools.
- It is necessary to choose rounded cutouts that are made strictly towards the shaft.
- Optimal Thickness disk is 2 mm.
- The depth of the cuts made sometimes reaches 20 millimeters.
- 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 in 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 roughing attachments.
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. Expansion of functionality is provided by the use of different types of 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 way 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.
Angle grinder is a very useful tool that can be used in various industries. It is due to its versatility that it has become widespread both at industrial facilities and at the household level.
Types of nozzles for wood
As a tool for woodcarving, only angle grinders with speed control are suitable. Since the main purpose of the grinder is the grinding of homogeneous materials, then to the processing of a heterogeneous structure wooden materials must be approached very carefully.
The following types of circles for wood can be distinguished:
- Wood saw for grinder
- Cutting discs
- planers
- Grinding
Each of these parts must be used for its intended purpose.
saw blades
A saw blade for wood for a grinder consists of a metal circle with a chain attached to the edge. The design of special sawing tools is similar to those used for chainsaws. But saw blades are made of tungsten carbide. When a disk for a grinder on a tree hits a solid obstacle in the wood - knots, resin, metal, its base rotates without breaking the chain. With chain nozzles, it is quite easy to clean the logs from knots and bark, to give them the necessary initial shape.
Cutting discs
Various manufacturers produce and cutting wheels on wood specifically for angle grinders, for example, a Bosch cutting wheel. Their design differs significantly from the design of disks for circular saw. Usually they have side teeth that protect the nozzle from jamming. Differ cutting tools by number and shape of teeth:
- bevelled;
- straight;
- in the form of a trapezoid.
The first version of the shape of the teeth is considered universal. It is suitable for all types of wood with small amounts of work. When sawing wood from soft varieties, it is quite possible to use discs for a grinder on wood with a straight tooth. Trapezoidal teeth are capable of processing quite solid products from wood: chipboard, fiberboard, OSB boards.
In addition, cut-off wheels vary in diameter. The minimum size is 115x22 mm. The most commonly used circles with a diameter of 125 mm, they are universal and suitable for a wide range of jobs. Maximum possible size- 230 mm. But the latter option is undesirable to use when working with wood, as the likelihood of injury increases. Depending on the size chosen, the depth of cut in the wood will also be different.
Disks - planers for grinders
It is possible to use the angle grinder as a planer. For this, special circles are used - planers. Work with such nozzles is allowed without a protective casing, since solid discs are not destroyed. Many brands of wheels can be sharpened repeatedly. Before use, an additional handle must be installed on the angle grinder to more securely hold the tool with both hands.
Grinding discs
This type of circles allows you to use the machine for its intended purpose. For finishing and polishing wood surfaces can be used different kinds nozzles:
- cord brushes;
- end circles;
- petal nozzles;
- emery circles;
- cutting nozzles.
Rough processing of wood is carried out with the help of special cord brushes. End discs are designed to level the edges of parts, which is often required when miter sawing workpieces. They make a great file replacement.
The widest range sanding attachments- at the petal circles. Depending on the size of the abrasive grain, the wood surface can be cleaned with varying degrees grinding. With a gradual transition from using a coarse-grained nozzle to discs with finer grains, the effect of polishing parts is achieved. The system of trapezoidal petals, which are stacked with a three-quarter overlap on each other, wears rather slowly. If the embossed surface wooden product complex, then flap discs with a radial arrangement of abrasive strips are used.
Using sandpaper or sandpaper special nozzle allows you to grind fairly large areas of wooden surfaces. The ability to quickly change the sanding cover makes these tips versatile.
When deleting old coatings often use peeling nozzles. As a rule, this is a wire brush attached to a metal base. It can be located either parallel to the surface of the circle or perpendicular to it. There are options for fixing the bristles on the perimeter of the disc.
When working with wood, you need to make sure that it is fairly dry. If there is fungal damage on the surface of the workpiece, they must be cleaned to healthy wood.
Universal wood discs for grinder Graff Speedcutter
Wood disc for grinders Graff Speedcutter is Circular Saw with three teeth, which is intended for high-speed angle grinders. It is used in models with a maximum rotation speed of 12.2 thousand revolutions per minute.
The three carbide teeth are made of tungsten carbide and set at a 5° angle to the steel base of the tool. Thanks to this design and the special shape of each tooth, the cut surface is very clean and even. A disc is being made for the Graff Speedcutter grinder with a size of 125x22.23x3 mm. The cutting width of the wood is 3.8 mm.
Graff Speedcutter wheels are designed for artistic wood carving, cleaning and grinding of various types of wood. They are also used when cutting and selecting grooves in wood, its transverse cutting and longitudinal cutting. It is possible to use such nozzles when processing parts made of aerated concrete and gas silicate, fiberboard, chipboard, laminate, drywall.
Rules for working with the tool
Any tool can pose a serious danger if the rules of the instructions for using it in a particular situation are not followed. Bulgarian for cutting wood in this sense is no exception. The main points that are necessary when working with disks for an angle grinder - angle grinder on wood:
- Choosing the right circle size
- Installing a wood disk for a grinder
- Selecting the appropriate operating mode for the machine
- Refusal to use damaged circles
- Use of personal protective equipment
The nozzle size should be installed without problems under the protective cover of the machine. If this does not work, do not remove the protection. When working on wood with an angle grinder, it is necessary to use only special circles on wood for an angle grinder. The use of attachments that are designed to work on other materials may result in injury or a damaged tool. In order to avoid the destruction of the disk on wood for the grinder, the speed of the grinder must correspond to that indicated on the surface of the circle. Before starting work, it is worth checking the wood disk for defects and damage. If they are present, then it becomes dangerous to use. When working with the tool, eye and hand protection must be used. It would be best to use tight overalls.
