The grinder, or angle grinder (angle grinder), is a very popular tool that is very 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 its help. To process this material it is necessary to choose the right disk for the grinder on the tree. There are many types of nozzles that differ in characteristics and purpose.
Varieties of disks for grinders: the most suitable circles for the tree
The range of nozzles for this tool is quite wide. Products are classified by purpose, depending on what can be divided into 3 main groups of circles for angle grinders:
- diamond coated;
Saw. They are similar to standard saws, but are made from other materials. The most common option is tungsten carbide wheels. They are not suitable for working with wood.
Diamond coated. This group of circles for the grinder is the most extensive. The high popularity of diamond-coated tips is determined by a wide operational spectrum. With the help of such circles can be processed metal parts, as well as elements of stone and concrete. For wood, such disks are not used.
Note! The use of angle grinders requires adherence to certain rules. One of them claims that it is impossible to use circles of larger diameter than indicated in the passport of the device.
Abrasive. Differ in high universality. Abrasive discs are used not only for cutting, but also for grinding and polishing surfaces. Products from this group are used for wood processing.
These products are differentiated by one more feature – dimensions. The modern market provides a wide range of products whose dimensions range from 115 to 230 mm. The 115 mm wood disc for the grinder is the most compact and is used for quick and accurate cutting of material. It should be noted that the largest discs are not suitable for working with wooden surfaces.
Many experts do not recommend using grinder for cutting and processing wood. This is due to the principle of the device and the characteristics of the material itself. However, the variety of disks for angle grinders is growing every year. They can be divided by the features of work on several types.
Circular saws. Such circles on a tree for grinders are used, as a rule, for more technological equipment, but many install them on angle grinders. They are divided into two types: large diameter tipped and more compact without tack.
Chained. Ideal for working with wooden materials. Many people are interested in the question of whether it is possible to cut a tree with a grinder. An unambiguous answer to it does not exist, 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. This design has many advantages. This nozzle is most often used to perform a smooth cutting board. With it, you can handle 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 security when working with wood. Compact products belonging to this group have 3 teeth, and more overall ones – 4. This group also includes cutting discs for the grinder on a 125 mm tree of wood. Such products perfectly cope with their functions. They can be used to cut wood along and across fibers. In addition to standard features, such discs are used to organize grooves in blanks.
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.
Useful information! With the help of the segment nozzle you can work with wood of any strength and viscosity. It is distinguished by high safety and is able to resist even metallic inclusions present in some workpieces (screws, nails, etc.).
In this case, the saw blade is performed using a chain from a chainsaw. Such a nozzle is the most suitable for working with wood, as it has the greatest efficiency. Chain drive on wood for grinders are also considered the safest. The use of this nozzle significantly reduces the chance of injury if the tool is stuck.
If the disc falls on a solid element of the tree (for example, a knot) during operation, the chain does not break. This is due to turning the base. Such nozzles are very popular when it is necessary to clean the trunk of a tree from bark and knots.
Chain saw blades for wood grinders with a chain are used for various kinds of work. With their help, you can remove the branches of trees, as well as cut boards of small thickness. The functionality of chain products can be used as a roughing tool. They are great at removing bark.
With the help of the saw blade, you can make an even cut of the floorboard, plywood, fiberboard, chipboard, as well as the usual unedged and cut wood 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, the device is likely to overheat.
For the manufacture of such products using a 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 the hands, therefore 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 can have a different arrangement of teeth. A variety of types of products on this basis allows you to choose the most suitable for a particular situation nozzle. The shape and frequency of teeth arrangement also play a very important role. The most common circle size for working with wood is 125 mm. If you decide to choose the most versatile version of the cutting saw blade on a 125 mm grinder for a grinder, then it is recommended to purchase the product with bevelled teeth.
Useful information! Circles that have straight teeth are best suited for working with soft tree species. Softwood boards are also processed using such attachments.
These products may have teeth, which in their form resemble a trapezoid. They are characterized by a wider operational area and are used for cutting boards having an average density. With this circle you can cut the following materials:
- USB plates;
The saw blades for wood for grinders of this type have some design features that are caused by their purpose. For example, during operation, the products easily overheat, so they have special slots that 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 these slots may be different, but not more than 2 mm. As for their depth, it does not exceed 20 mm.
With the help of the 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 accessories. They are classified by several indicators: shape, design and purpose.
Peeling circles are used to remove bark from logs or boards. Thanks to them, you can easily remove excess wood from the end surface of the board. They may have special spikes or chips.
Rough discs on wood for grinders are also used to level the surface of boards. Such circles are equipped with special spikes, which are placed on a flat plane. This function is very useful because it allows you to polish the boards from which the flooring is constructed.
On sale you can find stripping products consisting of twisted wire. They are called korshchetkami. Such tips on the grinder for processing wood are of two types, depending on the characteristics of their structure. The first option provides for 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.
Korshchetki used to remove paints and varnishes from wooden surfaces. It is important to note that most often these nozzles are used to remove paint and rust from metal pipes.
Note! For wooden parts, it is necessary to choose a thinner wire that does not damage the workpiece itself. These products are suitable for different types of wood.
Roughing discs on wood equipped with wire turns are also used for brushing. This event allows you to give the wood an unusual look, artificially aging it. However, with the help of the grinder, which has a stripped wire attachment, it is possible to process only small volumes of wood. Therefore, this element is not recommended for industrial brushes.
Sanding and polishing wood are done using special tools that are used for grinders. Such products include a metal base on which the grinding wheel is fixed. Fastening, as a rule, is made by means of a flypaper.
Any Bulgarian must necessarily be equipped with a speed regulator, which must be converted to the minimum position. When working with cutting discs for the grinder is very important to observe the right angle. Otherwise, the cutting process will be uneven, and the device itself may jam.
LBM can be used for wood processing, but before using it, the technical features of various nozzles should be studied. Products that are used for grinding and polishing, do not carry any danger, and they are easy to use. Wood cutting discs require careful selection. During operation, you must follow the safety instructions and do not deviate from them.
