Hammer drills - Drills - Cordless & Electric - serafimov-systems.eu

The professional perforator is characterized by quality impact, greater impact force, greater tool stroke, greater power than the impact drill. The cartridge is of the SDS type. The set usually has a normal chuck with a key and a transition tail, which allows the use of the perforator as a normal drill. The perforator has the possibility to provide longitudinal movement (beating) simultaneously with the rotation. He handles bricks very well, and his main activity is to drill concrete with a quality drill.

The perforator is a percussion machine, which together with the percussion provides rotation of the working tool. Unlike the drill / drill, the drill does not cut the hole with the sharp edge of the drill, but drills the hole with a drill, like a chisel, with mechanized rotation and impact. Therefore, sharpening drills is more like sharpening a chisel than a drill. The impact force is determined by the impact energy in joules and the power of the motor in watts.

A pneumatic, less commonly electromagnetic mechanism is used to create a pulse directed at the material being processed. In the case of pneumatic mechanisms, the reverse movement occurs due to ricocheting and suction. The device of the perforator has a number of similarities with the drill / drill. The first perforators were developed in 1851 specifically for the mining industry. In 1932, the first electric hammer was introduced, which was modified into an electric hammer.
