Tool punch - what is it and what is it for?

The market of power tools is strictly segmented by types of equipment, which, depending on the characteristics, focuses on specific tasks. The range of operations can be quite wide. Although multifunctionality gives obvious advantages, the most high-quality technique is still aimed at a limited range of work. There are also tools whose capabilities and effectiveness are organically interfaced with universality. These include a puncher. What is this tool from the builder's point of view? In essence, this is an impact drill that allows holes in solid materials to be made.

The device and the principle of operation

The function of the perforator is realized due to the pneumatic mechanism, which drives the piston, which, in turn, acts on the firing pin. In the process of performing the action, the impact force is translated into a snap with reciprocating movements. As a result, the working part comes into contact with a solid substrate, which leads to the destruction of its structure. It should be noted that the best perforator with the most effective effect has a power of about 2000 watts. However, for home purposes, the optimal is not so much powerful as an ergonomic tool. Such models are the closest to traditional screwdrivers, since they also cope with the tasks of drilling in non-solid building materials. Professional punchers are rarely used for such needs.

What tasks does it solve?

As already noted, it is the impact force that is the main difference that the perforator possesses. What is impact action in the context of construction work? This is the ability of the equipment to make holes and niches of a different format in concrete, stone and brick. Such activities are usually performed during the laying of communications. Accordingly, before the work should be prepared and the necessary equipment.

For work with a water pipe or sewerage, drills and crowns of large diameter are required - a maximum of 160 mm. However, not every model can be provided with such a nozzle. It depends on what kind of cartridge is used for the perforator, although modern modifications support the possibility of using adapters. The minimum drilling diameter on the average is 10-15 mm. This is sufficient to form holes for electrotechnical communications.

Kinds of tools

The main classification of the perforators involves a separation according to the principle of nutrition. Traditionally, this tool is released in a network format, that is, with the connection to the outlet. The drawbacks of such models include the limitations associated with the length of the cable. This disadvantage is deprived of a battery puncher, which is most often powered by lithium-ion batteries. The owner of such equipment can work even in the distance from power sources, which is very convenient on open construction sites. But in this case there are already temporary work restrictions, due to the capacity of the battery pack.

There is one more classification of modern perforators - the type of cartridge. There are SDS-plus and SDS-max systems. The first allows you to quickly change the rig in the form of drills with shanks up to 10 mm, and the second can work with diameters up to 18 mm.

Popular brands

Today, on the market are available models of punchers from a wide variety of manufacturers, both for professional and domestic purposes. The most high-quality products are produced by manufacturers Makita, Interskol, Hitachi, etc. In the lines of these brands you can find high-performance universal devices with impact strength of about 30 J. Also for simple operations with wood and soft metals you can find inexpensive, But comfortable models, the impact potential of which is 3 J. To solve critical tasks in the professional sphere it is desirable to apply to brands of the level "Metabo" and "Bosch", in the families of which you can find a multifunctional punch. What is a modern and multifunctional puncher? It is not just a drill with a shock action, but also an apparatus that has extensive auxiliary equipment. These same companies, for example, produce industrial vacuum cleaners, which help to eliminate one of the main problems of such a tool - the formation of large amounts of dirt in the course of work.

Repair and maintenance

A quality tool most often fails due to violations of the rules of operation. To minimize the risk of damage to the device, you should regularly lubricate the functional elements with a special oil, check the reliability of the fasteners and, most importantly, clean the surfaces of the housing from dust every time after work. As for the faults of the internal "stuffing", they are basically reduced to a malfunction in the electric motor, poor fixing of the rigging, shorting in the stator, etc. Therefore, just in case, one should have such spare parts for the perforator as a brush unit, a collector and the one The same reducer. To increase the reliability of the electric motor, it is also necessary to change the carbon brushes in a timely manner.

Conclusion

The puncher has many options. In addition to the main classifications, it is worth considering the values for specific characteristics. For example, the force of impact, power, the size of the cartridge - all this will help to make the best choice. Do not forget about the additional functions that are endowed with a modern perforator. What is a modern multifunctional power tool? It features an immaculately functioning internal base, as well as ergonomic devices. Thus, professional models are often complemented by a second handle for a more comfortable retention of the device during the execution of the impact. Increasingly appear and compact flashlights as an auxiliary tooling. With their help, the user can perform drilling and chiselling operations in hard-to-reach places without additional equipment.
