Traditional locksmith operations are gradually changing in the nature of production, which is affected by the development of the tool. The capabilities of machine tools, pneumatic and electric machines merge with hand-held devices, as a result, allowing the master to more effectively deal with the tasks of cutting and cutting. Nevertheless, the demand remains for a simple classical instrument.
Using a chisel, you can get a high-precision groove, groove or even a technical hole with maximum accuracy, limited only by the skill of the user.
Design and principle of operation
The typical design of this tool is based on a metal rod. One end is functional and implements chopping actions. The other end is provided with a nozzle in the form of a handle, which, in turn, has a dual purpose. Firstly, the chisel has a shock action precisely through the holder. Secondly, the master positions the cutter, holding the tool by the handle.
It is important to note the variety of configuration solutions of the chisel. Both the working cutting part and the holder can be performed in different versions. Even the handle has different sections that determine where the bench chisel can be used. GOST 7211 86 identifies several types of toolholders, including models with an I-beam, hexagonal, oval and semi-oval cross-section. As for the cutting head, then it can be flat, round, square, etc.
Tool varieties
Fundamental differences in the models of the chisel are determined by functional capabilities, which also depend on the design and shape of the tool. For example, for home use, experts recommend versions with a tread. This is a chisel whose handle is provided with a hand guard. In practice, this means a more confident grip and increased protection against accidental impact.
Specially for performing caulking, models with an extended work area are used. If you need to choose a metalwork chisel for sealing cracks, joints or cleaning flat surfaces, then this option may well be preferred. Of course, it will differ from a spatula in strength and rigidity. There is also a category intended for power actions. This is a weighted tool that can be used in the process of precise and accurate destruction of concrete and brick structures.
Of course, there are hybrid versions of chisels designed for universal use. Moreover, some models provide for the possibility of changing the working tip, which, however, does not affect the reliability of the tool in the best way.
User's manual
Before starting work, it is necessary to check the condition of the tool. Particular attention is paid to the handle, as it is often not made of metal and may have physical damage. Both the metal functional part and the holder must be in a cleaned state.
The workflow consists of cyclically repeated cutting operations. First you need to fix the bench tool. The chisel is installed in place of the cut and held by the left hand. Next, using a sledgehammer or hammer, you need to strike with the right hand from the shoulder at the end of the holder.
Impact energy will depend on the applied force and, accordingly, determine the nature of the result. In this way, depending on the characteristics of the chisel itself, it is possible to carry out a rough trimming of the log and perform a neat figured cut on the surface of the wood massif.
Manufacturer's Reviews
Hand tools are quite widely represented by domestic manufacturers. Good feedback is given to the Zubr, Enkor and Russia brands. Another thing is that most of the models of these brands are simple chisels, often lacking functional handles.
This, by the way, has its own plus. Owners of monolithic bar tools of this type note their high reliability and durability. Moreover, the cost of this product rarely exceeds 500 rubles. A foreign metal chisel, the price of which can be about 2-3 thousand rubles, is often supplied in sets. For example, quality kits are supplied by manufacturers Jonnesway and Stanley, using new technological materials in the manufacture of tools.
What to consider when choosing a chisel?
Appointment is the main selection criterion. The cross-sectional shape, the presence of a handle and tread - these and other design features will subsequently determine both the ergonomics of the model and its effectiveness in the performance of certain working actions. Along with this, the resource of the product should be taken into account. According to GOST, a chisel with a dull radius in the working part should have no more than 0.4 mm.
In order not to lose out on the choice for this parameter, it is advisable to focus on versions of high-strength tool steels. As for typesetting kits, they should be purchased with the expectation of performing various locksmith and carpentry tasks.
For a highly specialized application, it makes sense to acquire a purposefully model with suitable properties. Again, this choice takes into account the cross-section, the width of the working base, the possibilities for protecting hands and other characteristics.
Conclusion
Tool manufacturers are actively expanding the range of electric and pneumatic tools that replace the functions of conventional hand models. So, the bench chisel is already competing with some modifications of planers and planing machines. But here it is important to understand that far from all operational capabilities, the transition to mechanics will pay off.
Of course, the same electrical devices will benefit in speed and performance. But if you need to perform decorative finishes or dot linings of a wooden base, then it is better not to find a chisel. The rest as processing by this tool will depend on the skills of the contractor and the complexity of the operation.
