Рынок электроинструмента строго сегментирован по types of equipment, which, depending on the characteristics, is oriented to specific tasks. In this case, the range of operations performed can be quite wide. Although multifunctionality provides obvious advantages, the most high-quality technology still focuses on a limited range of work. There are also tools whose capabilities and effectiveness are organically matched with versatility. These include perforator. What is this tool from the point of view of the builder? In essence, it is a hammer drill that allows holes to be made in hard materials.
Perforator function is implemented bypneumatic mechanism that actuates the piston, which, in turn, affects the firing pin. In the process of performing the working action, the force of impact is transmitted to the equipment with reciprocating movements. The result is the contact of the working part with a solid base, which leads to the destruction of its structure. It should be noted that the best perforator with the most effective impact has a capacity of about 2000 watts. However, for household purposes, the optimal will be not so much a powerful as an ergonomic tool. Such models are the closest to traditional screwdrivers, since they also cope with drilling tasks in non-rigid building materials. Professional punchers are rarely used for such needs.
Как уже отмечалось, именно ударное силовое impact is the main difference that the punch has. What is the impact action in the context of the construction work? This is the ability of equipment to make holes and niches of other formats in concrete, stone and brick. Such activities are usually performed during the construction of communications. Accordingly, before work should be prepared and the necessary equipment.
For work with plumbing or sewagelarge-diameter drills and crowns are required — a maximum of 160 mm. However, not every model can be provided with such a nozzle. It depends on which cartridge is used for the perforator, although modern modifications support the possibility of using adapters. The minimum drilling diameter is on average 10-15 mm. This is sufficient for the formation of holes for electrical communications.
The main classification of drills suggestsnutritional separation. Traditionally, this tool is available in a network format, that is, with a connection to the outlet. The disadvantages of such models include limitations associated with cable length. This minus is deprived of the battery punch, which is often powered by lithium-ion batteries. The owner of such equipment can work even away from energy sources, which is very convenient on open construction sites. But in this case there are already temporary restrictions of work, due to the capacity of the battery pack.
There is another classification of modernperforators - as a cartridge. There are systems SDS-plus and SDS-max. The first allows you to quickly change the equipment in the form of drills with shanks up to 10 mm, and the second can work with diameters up to 18 mm.
Today on the market are available models of drills froma variety of manufacturers, both for professional and for domestic purposes. The most high-quality products are produced by manufacturers Makit, Interskol, Hitachi, etc. In the lines of these brands you can find high-performance universal devices with a impact force of about 30 J. Also, you can find inexpensive, but convenient models, the impact potential of which is 3 J. To solve important tasks in the professional sphere, it is desirable to turn to brands of “Metabo” and “Bosch”, in whose families one can find a multifunction punch. What is a modern and multifunctional punch? This is not just a hammer drill, but also an apparatus that has a wide range of accessories. These companies, for example, produce industrial vacuum cleaners, which allow to eliminate one of the main problems of such a tool - the formation of large volumes of dirt during work.
A quality tool most often comes out ofoperation due to violations of the rules of operation. In order to minimize the risk of damage to the apparatus, it is necessary to regularly lubricate the functional elements with special oil, check the reliability of the fasteners and, most importantly, each time after work, clean the surfaces of the case from dust. As for the internal “filling” problems, they mainly boil down to a malfunction of the electric motor, poor fixation of the equipment, short circuit in the stator, etc. Therefore, just in case, you should have spare parts for the perforator, such as the brush unit, the collector and same gearbox. To improve the reliability of the motor, you should also change the carbon brushes in a timely manner.
The puncher has many options.In addition to the main classifications, it is worth considering the values for specific characteristics. For example, the impact force, power, cartridge size - all this will help to make the best choice. Do not forget about the additional features that endows the modern punch. What is a modern multifunctional power tool? It is distinguished by a perfectly functioning internal base, as well as ergonomic devices. Thus, professional models are often supplemented with a second handle for a more comfortable holding of the device during the execution of the shock. Compact lanterns are increasingly appearing as auxiliary equipment. With their help, the user can perform drilling and chiseling operations in hard-to-reach places without additional inventory.
