A chisel is a common hand tool that is used in the processing of wood, metal, stone, is a kind of chisel. It consists of a wooden or plastic handle and a metal cutter. The trapezoidal, square or rectangular blade of the bit has a beveled edge. This allows joiners to form any hole, groove, recess, select excess material, and cut the workpieces to the desired shape.
The chisel and chisel have a similar shape, the principle of assembly. It implies tight fixation of the shank of the cutting blade in the handle. Reliability of fastening is provided by a cap with a sealed neck to transmit more force. When working with wood, the bit is constantly subjected to increased mechanical stress, because hollowing holes in materials with a solid structure is usually accompanied by blows of a mallet on the handle. The handle is made of hardwood or heavy-duty synthetic polymers. If the handle is wooden, it is crimped with a metal ring that increases the strength of the part, preventing it from cracking.
Tool varieties
Depending on the size, shape of the blade, tools are designed for different types of work:
- A flat chisel, which is called ordinary, carpentry or thick, is common among craftsmen whose work is related to wood processing. It has a dense working canvas, and the blade has a rectangular or square profile. Products have a large margin of safety, so they are used in work requiring effort.
- The chamfered bit has a trapezoidal web shape, a blade with an elongated beveled edge. It is used to form grooves with straight edges. It is used in the processing of corner elements of the workpiece. The blade has an elongated bevel, the hand tool can easily penetrate those inaccessible places where other samples will not pass.
- A semicircular chisel allows you to select the fibers inside the deck. Differences of semicircular devices from chisels are insignificant.
- A narrow chisel differs from all others in that its blade is longer, thinner, and the cutting edge itself is more beveled, more often has a rectangular configuration. This type is best suited for stripping after processing a site with a carpentry bit..
- The mini chisel got its name because of its small size and short blade. This miniature tool is suitable for delicate, delicate work.
- The L-shaped bit is equipped with a curved blade (letter "G"). It is convenient for them to choose grooves, rectangular or square holes for installing accessories, and to form right angles at the workpieces.
- Long is intended for work on a significant penetration into the material. The difference is in the blade, which has a long, flexible blade.
- A large chisel or slick refers to a hand tool, the blade of which reaches a length of 60 cm, the maximum value of its width is up to 10 cm. The dimensions of the sample require considerable weight, so effort will be required. The scope of use of the slick is shipbuilding or rough carpentry (removing bark, rough sampling of material from large-sized blanks).
- Wide designed for construction work. It has a wide, relatively thin blade. This is convenient when removing parquet, dismantling other building materials (screeds, paintwork).
- The chamfered bit has a slanting edge that must be sharpened at an angle of 45–70 degrees. The cutting edge can be chamfered in any direction.. With the help of this chisel, the craftsmen manage to make grooves, recesses, if it is inconvenient to work L-shaped or straight.
- A medical chisel with which dentists remove a decayed tooth or perform orthopedic surgery. The difference between this sharpened device is the integrity of the instrument, consisting of medical steel. This allows sterilization.
Differences from Chisels
The main difference between chisels and chisels is the thinner steel from which the second sample is made. Chisels perform delicate operations, and the chisel is more suitable for grooving.
The chisel handle has a dome-shaped configuration, convenient for pushing hands, it is not intended for delivering strong blows, otherwise the part will simply fly apart into pieces.
Chisels - a group of hand tools with a flat or grooved shape of the cutter. They differ in length, blade width (from 4 to 40 mm). Sometimes masters have to consistently use several chisels of different sizes for the best result. There are similarities to working with a chisel.
In the manufacture of chisels, more durable steel is used. This provides the necessary sharpening sharpness for thin, precise cutting of the material. A blunt tool will tear wood, making the workpiece an uneven, rough surface that needs refinement. Joiners do not recommend using a chisel as a bit.
