Chisel: purpose, varieties, operating rules

Each owner in the home arsenal should have a set of tools. One of the most important and necessary items is considered to be a chisel, it is referred to as impact cutting.

A chisel is a tool whose main purpose is processing of hard material, such as stone, wood. It looks like a metal bar with one side flat and the other sharpened on both sides. The rods of the object can be oval, rectangular, multifaceted.

Due to the design features of the tool, it is classified as manual. Also, the chisel can be used as an attachment for a pneumatic hammer, which is attached to the hammer drill. To keep the risk of injury low, rubber fungi of an expanding nature are installed on objects. The latter can also be created from other material.

The use of the tool is based on the impact of a mechanical nature with destruction. The chisel is characterized by a wide range of applications:

• splitting stones;
• cutting metal;
• knocking down ceramic tiles;
• beating off caps from rivets;
• unwinding of bolts, nuts.

The advantageous characteristics of the chisel include strength and reliability, which are ensured thanks to the high-quality metal used for the manufacture. The result of working with this tool is a high-quality cutting of material. User reviews with a chisel indicate that the item is capable of withstanding high shock loads. The hardened working parts of the chisel ensure its strength and durability.

There are many models that differ in size, function. Depending on the purpose, the user can purchase a tool that works on metal, concrete, stone.

• Locksmiths. This version of the unit is one of the most common; it is used for metal that is not hardened.
• Peaks used in conjunction with power tools. The latter can be rock drills, jackhammers, construction chisels, pneumatic breakers. The lance-shaped device is very common and does its job well.
• Kreutzmeisel. This item is equipped with a pointed tapered edge. This design allows easy execution of grooves, as well as small grooves on the metal surface.

• Grooving Is a species that is equipped with a specially designed edge. With the help of the latter, various carvings are made on stone and metal surfaces. A blacksmith's chisel with a handle is used for cutting cold and hot metal.
• Spatula chisel designed for punching holes in walls, it is necessary to crush and break hard material. The raw material for manufacturing is high strength steel, the end of the tool has a blade-like appearance.
• Pneumatic device equipped with teeth that are similar to the teeth of hammer drills. This kind of tool has found its way into car repair shops. The chisel helps to cut excess iron along the welded seams.

Chisels, which are designed to work on metal and on stone, differ, although outwardly they are quite similar. The presence of a cutting edge, a blade with a wide shape indicates that the object is inherent in working with stones. A tool that works with metals, usually solid. It is characterized by a special hardening, therefore it has a hard cutting edge that can withstand hammer blows.

Before you buy a chisel, you should decide on its purpose. You should definitely pay attention to the material from which it is made, to the quality of processing, dimensions, shape, hand protectors, as well as cost. Do not forget that too low a price and a little-known manufacturer may indicate poor quality of the product. If the tool is made of metal of increased softness or with an unhardened chisel, then it will quickly become unusable.

A good tool is convenient to use, it will be functional for a long time. Appointment is the main selection criterion. In addition, the ergonomics of the tools depend on the shape of the section, the presence of handles, protectors, as well as how effective they will be in performing a certain job. Also, do not forget about the resource of the product: according to GOST, the working fraction of the bluntness radius should be no more than 0.4 millimeters. To make the right choice, you should give preference to a product made of high grade steel. If the chisel is to be used in a narrow area, then its properties must be appropriate.

Despite the fact that the modern market for tools implements a lot of electrical options, the chisel does not lose its popularity. To use the object correctly, it is worth knowing the features of the tools. Processes using a chisel must be careful and quality at the same time.

Basic rules of use:

• checking the reliability of the fit of the hammer on the handle;
• putting on glasses and gloves before starting the procedure;
• determination of tool dryness;
• when working with metal, it is worth taking into account the type, thickness of the metal.

If the material does not consist of one sheet, then the felling should take place in more than one approach. If it is necessary to separate a part of the wire, do not do it with a single swing. First you need to make a small incision, then break off the rod. The presence of fungus in the modern chisel model has a protective function.

Before starting the process of using the chisel, you should make sure that it is in good condition. The handle is worthy of close attention, as malfunctions on it can lead to damage. The metal functional part must always be clean.

The workflow is a cutting operation that is constantly repeated. The first step is to fix the plumbing tool. The chisel must be installed in the place of the cut, it is held with the help of the left limb. After that, hammers or sledgehammers should be involved in the process. Using the right hand, it is worth striking from the shoulder.

In order for the chisel to perform its functions normally, it should be sharpened. Depending on the purpose, the sharpening angle can be 35, 45, 60, 70 degrees. To prevent chipping of the blades, it is made slightly dull. Over time, deterioration of the cutting edge may occur. Only sharpening the unit can solve the problem; in this case, you can use emery.

Before the start of the procedure, the heated instrument is immersed in cold water. This action helps to harden the chisel.Sharpening the object should be carried out along the part of the end of the emery circle. The chisel blade should be set in the opposite direction to the emery machine, so the sparks will be directed to the floor. The duration of sharpening is influenced by the power of the device, the temperature of the environment, usually the process lasts from 30 seconds to a minute. If the edge is overexposed, strong heating will occur and the chisel may lose its hardness.
