Chain saw blade for wood for an angle grinder. Grinder disc for wood: how to choose the right grinding and cutting wheel? Choosing a saw blade for an angle grinder for wood
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 a 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:
- Cut-off
- Grinding (cleaning)
- 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 permanently secure the angle grinder 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 the saw blade has such soldering, then they do not wear out so 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. She guarantees the product high stability 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. There are also “thin +” discs, which use a material with an additional bumper; it reduces the blocking of the saw during its operation. This saw blade is suitable for longitudinal and cross cutting of wood, as well as other materials. Similar materials with high cutting precision are also used in furniture and wood processing production.
Features when working with saw blades
When working with a saw blade on wood, you need to exercise special care and skill, best wear a special uniform and safety glasses, gloves. The difficulty of working with wood is that wood is easier to cut, so it is necessary to maintain control in the operation of the tool. Experts recommend using tools of low power and speed when working with wood, the most best option- 1,000 rpm.
The quality of the grinder and the cutter are no less important; the final result of the work and its safety will depend on this. It is best to give preference to a proven tool and hear the opinion of experts to be sure of a positive result.
Grinding wheels
For execution various works made using a grinder grinding and polishing wheels, They may be:
- Spongy
- Felt
- With replaceable sandpaper
- Fabric
The material is selected depending on the surface that is planned to be sanded. To process wood species, flap grinding wheels are used; they are made of sandpaper, which is fixed to a rigid frame. Sandpaper can be coarse or fine grain; the markings can be seen on the product itself.
If planned make wood smooth, then it is best to use a fine-grained wheel to remove a small layer of wood - medium-grained. If you need to remove old paint, then you need to use a coarse wheel.
By design, grinding wheels can be flap, movable and hard. Petal ones give the most smooth surface wood, therefore they are used as finishing wheels.
Conclusion
When working with an angle grinder, you should always follow safety precautions. It is good when the tool is equipped with a stop handle and a protective casing. Devices that have a chainsaw chain at the edge are considered safe; it is specially installed there. If one of the teeth jams, the disk rotates idle, and this reduces the risk of injury.
The grinder, or angle grinder (angle grinder), is a very popular tool that is distinguished by its versatility. It is used in most construction work. Many people are interested in the question of whether it is possible to saw a tree with its help. To process this material, you need to choose the right wood disc for the grinder. There are many types of nozzles, differing in characteristics and purpose.
The range of attachments for this tool is quite wide. Products are classified according to purpose, depending on which 3 main groups of wheels for angle grinders can be distinguished:
- saws;
- with diamond coating;
- abrasive.
Saws. They are similar to standard saws, but are made from different materials. The most common option is tungsten carbide discs. They are not suitable for working with wood.
Diamond coated. This group of circles for an angle grinder is the most extensive. The high popularity of diamond-coated nozzles is due to their wide operational range. With the help of such circles you can carry out processing metal parts, as well as elements made of stone and concrete. Such disks are not used for wood.
Note! The use of angle grinders requires compliance with certain rules. One of them states that you cannot use circles with a larger diameter than indicated in the device passport.
Abrasive. They are highly versatile. Abrasive discs are used not only for cutting, but also for grinding and polishing surfaces. Products from this group are also used for wood processing.
These products are differentiated by one more characteristic - dimensions. The modern market provides wide choose products whose sizes vary from 115 to 230 mm. The 115 mm wood grinder blade is the most compact and is used for quick 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 explained by the operating principle 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 into several types according to the characteristics of their work.
Circular saws. Such wood wheels 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 with soldering and more compact, without soldering.
Chain. Ideal for working with wooden materials. Many people are interested in the question of whether it is possible to cut wood with a grinder. There is no clear answer to this, but chain products are best suited for this purpose. The edge of the circle in this case is equipped with a chain on which the teeth are located. Similar design has many advantages. This attachment is most often used for smooth cutting of boards. It can also be used to process other materials: chipboard, fiberboard, plywood.
Saws with a small number of teeth. This type of circle was specially invented to ensure maximum human safety when working with wood. Compact products belonging to this group have 3 teeth, and larger ones have 4. This group also includes cutting discs for an angle grinder for wood 125 mm. Such products do an excellent job of their functions. They can be used to cut wood along and across the grain. In addition to standard functions, such disks are used to organize grooves in workpieces.
Segmental (material – tungsten carbide). Such products appeared relatively recently, but have already gained enormous popularity. Distinctive feature such products lack teeth. The edge of the disc consists of segments that are characterized by high strength.
Helpful information! Using a segment nozzle, you can work with wood of any strength and viscosity. It is highly safe and can withstand even metallic inclusions present in some workpieces (screws, nails, etc.).
Chain saw blades for wood: advantages of use
In this case, the saw blade is made using a chain from a chainsaw. This attachment is the most suitable for working with wood, as it has the greatest efficiency. A chain disk for wood for an angle grinder is also considered the safest. The use of this attachment significantly reduces the likelihood of injury if the tool jams.
If the disk hits a hard element of wood during operation (for example, a knot), the chain is not destroyed. This happens by turning the base. Such attachments are very popular when it is necessary to strip a tree trunk of bark and knots.
Wood saw blades for angle grinders with chain are used for various kinds works With their help you can remove tree branches, as well as cut boards of small thickness. Functionality chain products allow them to be used as roughing tools. They do an excellent job of removing bark.
Using a saw wheel 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 that will be processed with such a nozzle should be no more than 4 cm. Otherwise, there is a high probability of the device overheating.
Cutting disc for wood for an angle grinder: features
For the manufacture of such products they use special material– tungsten carbide. This is explained by the following: when working with an angle 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 operational safety, but the cost of such products is quite high.
Discs similar type may have different arrangement of teeth. A variety of product types based on this feature 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 important role. The most common wheel size for working with wood is 125 mm. If you decide to choose the most versatile option for cutting saw blade on 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 on soft woods. Boards from coniferous species are also processed using such attachments.
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 of medium density. Using this wheel you can cut the following materials:
- USB plates;
- fibreboards.
Wood saw blades for grinders 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, which can be empty or filled with copper. This measure allows you to compensate for the thermal expansion of the metal that occurs at high speeds. The width of such slots may vary, but not more than 2 mm. As for their depth, it does not exceed 20 mm.
Wood sanding disc for grinder: characteristics
With the help of a grinder you can not only cut and saw off wooden parts, but also carry out roughing work varying degrees of complexity. The modern market offers a large assortment such attachments. They are classified according to several indicators: shape, design and purpose.
Peeling wheels are used to remove bark from logs or boards. Thanks to them, you can easily remove excess wood from end surface boards. They may have special spikes or crumbs.
Wood grinding discs for grinders are also used to level the surface of boards. Such circles are equipped with special spikes that are placed on a flat surface. This function is very useful, as it allows you to polish the boards from which the floor covering is constructed.
On sale you can find stripping products consisting of twisted wire. They are usually called brushes. There are two types of such attachments for grinders for woodworking, depending on the features of their structure. The first option provides for a base in the form of a glass to which a wire is attached. The second type is a disk with a wire fixed along the edge.
Brushes are used to eliminate paint and varnish materials from wooden surfaces. It is important to note that most often such nozzles are used to remove paint and rust from metal pipes.
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.
Wood sanding discs equipped with wire coils are also used for brushing. This event allows you to give the wood unusual look, artificially age her. However, with the help of an angle grinder equipped with a wire stripping attachment, only small volumes of wood can be processed. Thus, this element is not recommended for brushing on an industrial scale.
Grinding and polishing discs for wood for an angle grinder
Sanding and polishing wood is carried out using special attachments that are used for grinders. Such products include a metal base onto which the grinding wheel is fixed. Fastening is usually done using Velcro.
To use such an attachment on wood for an angle grinder, you need to fix it with a wrench (open-end) on the tool shaft. Quite often it is sold complete with a special adapter element, thanks to which it becomes possible to quickly attach it to a drill chuck. In turn, polishing requires the use of a more gentle material. Therefore, nozzles of this type are equipped with felt discs. They are also secured using Velcro.
Another option for a grinding wheel for an angle grinder is a flap wheel. Its design fully lives up to its name. It consists of a large number of sandpaper petals, closely spaced to each other. If desired, you can select the required paper grain size, which allows you to process wooden materials varying degrees of density.
Although the grinder is not considered the tool of choice 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 versions of discs for angle grinders leave small scratches on the wood. If you decide to carry out this process as efficiently as possible, then experts recommend purchasing a special device - a grinder. Angler grinders are usually used for materials that will subsequently be painted.
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 wood processing process itself, as a rule, proceeds in two stages. First of all, rough grinding is carried out, after which the material is subjected to finishing. For rough polishing, several types of attachments are used:
- peeling;
- brushes;
- end circles.
Sanding wood with a grinder using a grinding product is most often used to remove a layer old paint. Sometimes this type of attachment is used to remove varnish coating, if you can’t fix it manually. Such circles can have different reliefs, the features 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 their hardness, they are also divided into types. If necessary, it is possible to select the right tool, corresponding to one or another grinding option.
Helpful information! For rough processing, larger diameter wire is used.
End discs for grinding wood on an angle grinder are used when it is necessary to adjust the size of a part from the end. Often such products are used for regular leveling of the side surface during uneven cuts. The principle of operation of the end attachment resembles the operation of a file. The difference in this case is the high efficiency of the angle grinder.
The use of sanding attachments greatly simplifies processing wooden blanks. Such products allow restoration old furniture, removing paint and varnish compounds from its surface.
Grinding discs for grinders: flap wheels
After rough processing it may be necessary fine finishing. Of course, if the wood is subsequently painted, there is no need to bring its surface to a perfectly smooth state. However, in most cases finishing is a necessary event. To perform grinding, you can use a common attachment - a flap wheel.
The design of the petal disk 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 processing of the material and has a high degree of safety. It is almost impossible to get injured using this disc.
From size abrasive coating on the petals depends on the efficiency and speed of wood processing, as well as its appearance. For maximum smoothness, it is customary to use fine-grained products. Experts recommend using several of these sanding wheels for wood at once. This will make it possible to quickly rough cleaning, then finish the work with soft petals, bringing the workpiece to the desired degree of smoothness.
The use of such an attachment requires a certain skill from a person. Therefore, before starting to use petal circle It is recommended to practice on wooden parts.
Grinding wheel for grinder: soft processing and polishing
To carry out 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 flap attachments, abrasive particles are fixed with Velcro to the surface of the disk, and not to its end part.
A grinding disc for a wood grinder of this type has one advantage - ease of replacement. This procedure is performed without removing or disassembling the main nozzle, so using such discs is quite convenient. Sticky attachments can be easily purchased at construction market or order online. Selecting the desired grain size is not a problem in this case. With the help of such devices you can bring wooden surface to the desired state.
Polishing, which is carried out after grinding, can be carried out using special felt wheels. These attachments provide maximum smoothness. work surface, which is difficult to achieve using other tools. A large number of rotations of the angle grinder promotes uniform polishing of the wood.
Felt discs for an angle grinder include wool (densely compressed), which can have various characteristics(depending on need). On modern market you can find different types of nozzles:
- fine-haired;
- semi-coarse-haired;
- rough-haired.
Woodworking attachments are different high efficiency and quality. Alternating use of these discs allows you to achieve incredible results. The wood surface after using them can be compared to a mirror.
Safety rules when working with an angle grinder on wood
The use of angle grinders for wood processing requires a serious approach. Incorrect operation of an angle grinder can lead to injury, so before using it, experts advise paying attention to some rules for operating the device. For example, before replacing one attachment with another, you need to disconnect the angle grinder from the network. How to change a disc on an angle 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 necessary to unscrew the flange holding the element.
Note! Under no circumstances should the cover, which is used for protection, be removed from the angle grinder. If the circle breaks, this element will protect your face and other parts of the body from injury from fragments.
Processing of wood material with using angle grinders must be carried out with protective gloves. Saw and cutting blades for wood are best used on medium (in terms of power) devices. This can be explained quite simply: if the saw jams, then you still have a high chance of holding the tool in your hands. With a powerful device this will be much more difficult.
For cutting logs and boards, it is recommended to use attachments that have fine teeth. The smaller their dimensions, the less effort required to cut. Among other things, the likelihood of encountering hard wood fibers in the path of the disc is reduced.
Any angle grinder must be equipped with a speed controller, which must be set to the minimum position. When working with cutting discs for an angle grinder, it is very important to maintain a right angle. Otherwise, the cutting process will be uneven and the device itself may jam.
An angle grinder can be used for processing wood, but before you start using it, you should study the technical features of the various attachments. Products used for grinding and polishing do not pose any danger and are easy to use. Discs for cutting wood material require careful selection. During work, you must follow safety rules and not deviate from them.
Many homely owners have an angle grinder in their home arsenal - this is what people call an angle grinder. And so, when the need arises to work with wood: cut boards, cut down branches on trees or prepare firewood; and there is no corresponding electric saw at hand: circular, jigsaw, chain, etc.; some savvy craftsmen say to themselves: “So what?! After all, there is a Bulgarian! It’s quite possible to get by with it!” How right are such resourceful masters?.. This is exactly what our article is about.
Never place a saw blade on an angle grinder!
This is not just the title of the subtitle of the article, it is the cry from the heart of all power tool sellers. After all, they very often come to them with the same request: “Give me a saw blade for an angle grinder so that I can cut wood.” And they all unanimously answer in such cases: “You don’t cut wood with an angle grinder!” And in general, by definition, you can’t put a saw blade on an angle grinder!” Why is that? We addressed this question to the developers 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 it can easily cut and simple board, and a 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 dangerous, especially if you remove it from it. protective cover. After all, the grinder has a very high rotation speed, creating a centrifugal force that will significantly increase the load on the saw blade. In addition, a circular saw is structurally different from abrasive wheel– it has teeth, and this circumstance leads to increased vibration, especially if you install saw wheels on metal. As a result, such a load will significantly exceed the tensile strength of the web. circular saw, it can simply break during rotation. What this entails has probably already become clear to everyone. And in such a situation, nothing can save you from injury: neither the protective casing of the grinder, nor the personal protective equipment of the cutter.
To prove the danger of such disk “castling,” all kinds of tests were carried out. And in life there were many cases when a “savvy” owner was left without arms or legs. And in 2011, there was a unique case when a certain “economic” Volgograd resident decided to cut branches from a tree at his dacha. using an angle grinder and installed a circular saw blade on it. As a result, he was taken to the thoracic surgery department with a torn chest. Fortunately for the poor fellow, everything ended well.
Is it possible to install a grinder circle on a circular saw?
The question can be rephrased: is it possible circular saw use as an 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 machine is very poorly suited for such use. Yes, when you need an even cut, the saw will cope with this task better than grinder, but its protection from dust is much worse than the latter. Both the cutter and the tool will swallow dust - then it will take a long time to blow it out.
In addition, the rotation speed circular saw significantly lower than what is needed for efficient work circles from an angle grinder. For example, if you install a diamond on a circular saw abrasive disc and try to cut ceramic granite with it, the motor could easily burn out. And the circles themselves will wear out faster. After all, saw and abrasive discs are designed for different angular speeds.
And we repeat once again: do not use saw blades on an angle grinder! Better buy an inexpensive circular saw!

Even a schoolboy knows what a “grinder” is nowadays - it’s an angle Sander, designed for working with metal workpieces using special cutting and grinding wheels. Not everyone, but only professionals, know that such an electric tool can be used for processing wood, so this article is intended to fill this gap in the information available to ordinary users. Disc for an angle grinder for wood - types, general characteristics and standard sizes, as well as safety measures for use and a review of prices for popular models - this is the topic of this article from the editorial website
Depending on the type of discs used, the “grinder” in in capable hands can be used at various stages of working with wooden workpieces: from sawing to sanding
The “grinder” was not originally intended for sawing wood, especially for workpieces of significant thickness and hardwood. This is due design features of this type of tool and associated with such dangers of use:
- when the saw blade jams, it is difficult to hold the angle grinder in your hands, which can lead to injury;
Important! Jamming of the saw blade when using an angle grinder to cut wooden workpieces is the most common problem with this type of work, which is due to the softness and viscosity of the wood.
- Inhomogeneity of the wood structure due to the presence of knots can lead to damage to the saw blade being used and injury to the user.
Despite the potential danger of using an angle grinder as a tool for sawing wooden products, manufacturers of consumables, which include grinder discs, produce similar products.
Expert's point of view
Victor Isakin
Ask a Question“For processing workpieces of considerable thickness and at professional use It is most correct to use a tool originally designed for sawing wood, such as a circular saw and a circular saw.”
The main and most common uses of the “grinder” when working with wood are: peeling, grinding and polishing, for which manufacturers produce special types disks.
General characteristics of discs for grinders, depending on the type
Discs designed for different types of use vary in their design and the materials used in their manufacture. In this regard, different types Similar products have different general characteristics, which requires their separate consideration.
Cut-off models
- circular– considered “dangerous” saw blades;
- chain– are made using links intended for chain saws;
- with a small number of teeth– are the safest compared to circular analogues;
- tungsten carbide– the safest type of such equipment.
For your information! Circular discs come in two modifications: a “dangerous” and a “less dangerous” option. Distinctive feature Models of the “less dangerous” type are provided with anti-jamming protection provided by the teeth being set.
Chain modifications are less dangerous when used, because their design provides for a non-fixed landing saw chain on the surface of the disk.

Tool selection specialist for the 220 Volt retail chain
Ask a Question“If the saw chain jams during use, the disk mounted on the angle grinder continues to rotate, the tool does not break out of the hands, allowing it to be stopped in an emergency.”
Discs with a small number of teeth come in two types:
- with 3 teeth– used with small “grinders” with a diameter of up to 150 mm;
- with 4 teeth– used on large size grinders with a diameter of 230 mm.
A distinctive feature of models made from tungsten carbide is the absence of teeth on the cutting surface of the product. The cutting element is the segments located around the circumference of the disk.
Important! Tungsten carbide models are capable of sawing various metal products (nails, screws, etc.) that may end up in the workpiece without damaging the cutting elements or their integrity.
Discs for roughing work
For stripping wooden products, manufacturers produce several types of attachments that differ in design and types of materials used in their manufacture.
By design, such nozzles can be made in the form of:
- a disk with spikes or crumbs applied to its surface;
- glasses with cutting elements made of twisted wire inserted around its circumference;
- disk with wire turns mounted on its surface.

An angle grinder, whose real name is an angle grinder, is a universal tool. They almost never do without it construction works. But in order for the tool to last a long time, it is necessary to select the correct grinding discs. A disk for wood is fundamentally different from a disk for metal. What are its features, and what varieties are there?
Today the entire range is divided into three main areas:
- Saw blades. They resemble a regular saw, but are made from completely different materials. Until recently, such specimens could not be found, but now they are sold completely freely. The most preferred option is tungsten carbide.
- Diamond coated disc. The most popular variety. In turn, it is divided into solid and segmented. Their scope is different, but there is common feature— high-quality and accurate results of work on concrete, metal or stone.
- Abrasive. Universal consumables, suitable for any type of surface. It cuts, grinds and polishes well.
Of the listed disks, the first and second are not suitable for wood. Natural wood has a very dense structure, and if you use a diamond disc, the grinder will overheat to the point of breaking.
The products also vary in diameter. The most practical ones have a diameter of 125 mm; in rare cases, a compact disk is needed - 115 mm. There are specimens up to 230 mm, but they are not suitable for wood. Their use may cause injury.
Selecting cutting wheels for wood
Cutting discs are divided according to three parameters - diameter, depth of cut and shape/frequency of teeth. Choosing the right option, there are a few things to consider: how often the product will be used and for what kind of wood.
Coniferous and other soft woods can be easily cut with a straight-toothed blade. If you plan to cut different types of wood, it is better to take a universal wheel with alternately beveled teeth. There are also trapezoidal teeth that are ideal for cutting through wood. medium density and woody areas.
Selecting grinding and polishing wheels
If cutting a material requires certain skills, then almost anyone can grind. For this operation they usually use petal discs. Such a disk consists of several sandpaper petals arranged in a circle. Sandpaper provides a gentle sanding effect.
Another option is a Velcro abrasive disc. It is convenient to use, but even more convenient to change. Such circles do not last long, but also have a low cost. And, of course, they are many times more effective than the manual sandpaper method. For example, using such a circle you can polish parquet.
Preparing the tree
Whatever the blade for the grinder, the work cannot be done efficiently if the wood is not properly prepared. Here are some tips on this matter:
- the wood must be thoroughly dried;
- special abrasive attachments are suitable for removing paint or varnish from the surface;
- the work is carried out in two stages, roughing and finishing.
Discs and other tools that will be needed for complete sanding or polishing of wood:
- Cord brushes designed for rough grinding surfaces. They help give the product an acceptable shape.
- The next step in processing a piece of natural wood is to use a sanding attachment. If the subject is complex, you will also need to apply radial stripes.
- A felt circle made of pressed wool (coarse, fine or semi-coarse) will help get rid of the slightest roughness. With their help, the surface can be made almost mirror-like.
As you can see, when using various attachments, the grinder becomes universal tool for woodworking.
Saws (chain wheels)
Suitable for cutting boards less than 4 cm thick. Use requires extreme caution. During non-working hours, the disc must be kept in a case, and during operation it must be used only at the speed indicated on the product itself.
Also, goggles and protective gloves are required when working. It is important to remember that under no circumstances should you use regular circles designed for a circular saw on an angle grinder.
Using an angle grinder for milling
A wood cutter for an angle grinder can be dangerous in unprofessional hands. For a specialist, its use is acceptable.
The milling cutter helps to level the edge, make grooves, cut workpieces and cut out bowls for log houses. Even on non-uniform wood, the tool will not jam or be thrown off. However, before starting use, it is important to carefully read the instructions and also observe the required speed.
The choice of cutters for angle grinders is quite wide, no less than for a manual milling machine. They are not intended for precision machining, but are quite suitable for shaping.
Safety rules during operation
In order for the use of a wood disc for an angle grinder to bring only benefits and not injuries and damaged products, you must follow several important rules:
- choose the right circle according to size and properties;
- The operating mode of the machine must correspond to the requirements on the disk;
- Damaged wheels should not be used under any circumstances;
- Protect your hands and face with special devices and protective clothing.
The attachment should fit effortlessly under the angle grinder casing. If you can’t do this, then do not remove the casing, it is dangerous.
Why can’t you use saw blades with an angle grinder?
The hardness of wood can vary even within a few centimeters. It may also contain clumps of resin and knots. All these uneven areas lead to the saw blade stopping abruptly, as a result of which the grinder is torn out of your hands.
