Traditional locksmith operations are gradually changing in the nature of production, which is influenced by the development of the tool. The capabilities of machine tools, pneumatic and electric machines are spliced with manual devices, ultimately allowing the master to more effectively cope with the tasks of cutting and cutting. Nevertheless, the demand for a simple classical instrument remains.
Using a machinist's 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 of its ends is functional and implements chopping actions. The other end is provided with a handle-shaped attachment, which, in turn, has a dual purpose. Firstly, the impact action is exerted on the metalwork chisel precisely through the holder. Second, the master positions the cutter by holding the tool by the handle.
It is important to note the variety of chisel configuration solutions. Both the working cutting part and the holder can be made in different versions. Even the handle has differentsections that determine where a bench chisel can be used. GOST 7211 86 identifies several types of holders, including models with I-beam, hexagonal, oval and semi-oval sections. As for the cutting head, it can also be flat, round, square, etc.
Tool Varieties
Principal differences in chisel models are determined by functionality, which also depends on the design and shape of the tool. For example, for home use, experts recommend versions with a protector. This is a chisel, the handle of which is provided with a protective device for hands. In practice, this means a more confident grip and increased protection against accidental impact.
Specially for caulking, models with an extended working 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 designed for power effects. It is a weighted tool that can be used in the precise and precise demolition of concrete and masonry structures.
Of course, there are also hybrid versions of chisels designed for universal use. Moreover, some models provide for the possibility of changing the working tip, which, however, does not have the best effect on the reliability of the tool.
Operating instructions
Before starting work, you need to check the condition of the tool. Particular attention is paid to the handle, as it is often not made of metal and may be physically damaged. Both the metal functional part and the holder must be in a clean condition.
The workflow consists of cyclically repeated felling operations. First you need to fix the locksmith tool. The chisel is installed in the place of the cut and is held by the left hand. Further, using a sledgehammer or a hammer, it is necessary to strike with the right hand from the shoulder at the end of the holder.
Impact energy will depend on the applied effort and, accordingly, will determine the nature of the result. Depending on the characteristics of the chisel itself, in this way it is possible to make both a rough cleaning of the log and a neat figured cut on the surface of the wood mass.
Manufacturer Reviews
Locksmith's hand tools are quite widely represented by domestic manufacturers. The Zubr, Enkor and Rossiya brands receive good reviews. Another thing is that most of the models of these brands are simple chisels, often devoid of functional handles.
This, by the way, has its plus. Owners of core monolithic tools of this type note their high reliability and durability. At the same time, the cost of this product rarely exceeds 500 rubles. A foreign metalwork chisel, the price of which can be about 2-3 thousand rubles, is often supplied in sets. For example, quality kitssupplied 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 shape of the section, the presence of a handle and a protector - these and other design features will further determine the ergonomics of the model and its effectiveness in performing certain work actions. Along with this, the resource of the product should be taken into account. As GOST defines, a metalwork chisel should have no more than 0.4 mm in terms of the blunt radius in the working part.
In order not to miscalculate in the choice of this parameter, it is advisable to focus on versions from high-strength tool steels. As for the kits, they should be purchased with the expectation of performing various plumbing and carpentry tasks.
For a highly specialized application, it makes sense to purposefully acquire a model with suitable properties. Again, this choice takes into account the 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, a metalwork chisel is already competing with some modifications of planers and planers. But here it is important to understand that the transition to mechanics will not justify itself in terms of all operational capabilities.
Of course, the same electricdevices will benefit in speed and performance. But if you want to perform a decorative finish or point eyeliner on a wooden base, then you can’t find a better option for a chisel. The rest of the quality of processing by this tool will depend on the skills of the performer and the complexity of the operation performed.
