There are also the following types of chisels: shtiheli, rivets and marigold. These are more narrowly focused types of instruments, not related to semicircular ones, but worth mentioning.

It should also be noted that ready-made kits have various configurations . That is why many carpenters usually make some of the necessary chisels themselves. At the same time, the quality of work does not differ from the factory tool, and sometimes even surpasses it. Standard sizes have the following meanings: length with a handle - in the range of 125-290 mm, blade dimensions - in the range of 110-145 mm, width - in the range of 4-50 mm.

The defining dimensions of the tool are the height and bend radius.

With the help of a semicircular chisel, it is possible to perform the following operations: process wood along the fibers, make grooves and perpendicular notches . Also, a semicircular chisel is necessary when you need to make a pattern or ornament on the surface. After all, wood carving is an art that takes time, perseverance and skill.

Choice

A semicircular chisel is a carpentry tool that consists of a wooden or plastic handle and the blade itself . Due to the semicircular section, the cut from such a tool is obtained with a small depression. A similar tool, as already mentioned, is used for volumetric and flat-relief wood carving, for gouging semicircular grooves, making round holes and removing longitudinal chamfers.

It must be said that the width of the cutting part of such a tool ranges from 6 to 25 mm . For finer work, a very small model is needed. The thinner the blade, the more delicate work can be done. In general, every craftsman should have chisels with several blades of different sizes in his arsenal. When choosing a semicircular chisel, the quality of the steel from which it is made is a very important factor. High-carbon steel with a protective coating is a good material. This is often why art carving craftsmen construct a tool on their own. Factory kits are made from low-grade material that breaks and deteriorates easily.

The metal class and the manufacturer's name are applied to the surface of the metal part of the factory-made tool . A quality tool is not cheap. It should also be noted that each semicircular chisel has its own designation for classification and ease of selection. For example, semicircular wood chisels are designated with stamps No. 1 or No. 2, etc. These numbers determine the dimensions of the cutting corners.

The average price range of semicircular chisels is varied . A single tool can cost from 500 to 6000 rubles: it all depends on its characteristics and quality. But the sets are much more expensive. Among the factory tools, the following proven brands and brands can be distinguished: Biber, Dexx, Fit, Hardax.

Sharpening rules

Any tool will require sharpening over time. therefore this skill will sooner or later have to be learned if you are doing carpentry . To sharpen a chisel at home, you will need the following tools: vise, mallet, diamond stones, whetstones, abrasive paste, and sandpaper. First of all, it will be necessary to remove the rust from the old tool. This can be done, for example, with a steel brush that is attached to the drill.

The old tool is fixed in a vice . And don't forget about safety: gloves on your hands and goggles over your eyes. It is not so difficult to sharpen the incisors by hand on a semicircular chisel. But to sharpen the concave side of a semicircular chisel, you need some trick. We give a small bar with a width according to the dimensions of the chisel in a semicircular shape. Then, using double-sided tape, we attach sandpaper with different grain sizes to several bars. Then we begin to sharpen the tool.

It should be emphasized that at present, sharpening of a tool is possible in several different ways . The most common is the sharpening method with water stones, as it is this method that allows you to achieve the best result. The tool is sharpened using several stones, each of which has its own grain.

With this method of sharpening, the stones must be treated with water. In addition to water, oil is also used for this. Another way to sharpen is to use a sharpening stone . The grinder is used for rough processing of the tool. Sharpening on the machine requires accuracy. This is to avoid damage to the semicircular chisel.

It is important to monitor the RPM of the machine and cool the tool in time . When sharpening, do not press the blade hard against the rotating disc. It should be emphasized that the tool must be sharpened at least 2 times a year. The angle of sharpening of chisels is usually 20 degrees on average. After sharpening, the sharpness of the tool can be checked by light. If the chisel is well sharpened, it will not shine.

In general, it must be said that sharpening chisels is a rather complicated matter. Therefore, it is better to use a special sharpening device that will professionally and automatically do everything necessary.
