How to choose the right punch

The puncher is one of the most important tools in the construction or repair of buildings. It allows you to quickly and with minimal labor costs to make a recess in a durable material, to dismantle structures and perform other work. However, due to the huge assortment, there is a need for the right choice. This will be the subject of today’s article..

Key parameters to consider when buying a hammer drill

A power tool may have from one to three operating modes (drilling; drilling and impact; drilling, impact and crushing). Devices may vary in weight, some may reach 10 kilograms or more.

Key parameters to consider when buying a hammer drill

A power tool may have from one to three operating modes (drilling; drilling and impact; drilling, impact and crushing). Devices may vary in weight, some may reach 10 kilograms or more.

Impact energy. The most important characteristic of the device is the impact energy. To measure it, the units used are Joules. In simple models, the value can be 1-2 J, in more powerful ones it reaches 15 J. With an increase in the indicator, the diameter of the hole that can be made increases. If the impact energy is very small, then the apparatus is comparable in efficiency with a hammer drill. Rather, he will not punch recesses and holes, but drill them. This leads to a decrease in productivity and the rapid failure of devices.

Punch Power. In this parameter, the devices are inferior to electric drills, since much more energy is required for drilling than for drilling. When operating, the hammer drill shaft does not need such a high speed of rotation. Devices with SDS-Plus cartridges have a power of 400-800 watts, and with SDS-Max the figure can reach 1.2 kW.

Beat frequency. The indicator reports the number of strokes that the perforator piston performs in a minute. With its increase, the efficiency of drilling holes increases. Performance is affected by energy and impact frequency. A good combination of these two indicators will report on the durability and power of the device. At the same time, the brand must enjoy a good reputation so that it can be trusted.

As you can see, choosing a suitable hammer drill is not always easy. To do this, you need to allocate time, get acquainted with a number of characteristics and compare several models. However, it’s worth it! Having made a competent choice, you can purchase a high-quality and durable device!
