A rotary hammer is a power tool with a rotating machine tool for drilling in masonry, concrete, artificial and natural stone. It is equipped with a percussive hammer mechanism. The striking energy is independent of operator pressure.
If the hammer mechanism can be turned off, the rotary hammer can be used like a drill, if the rotation mechanism can be turned off, it turns into a percussion hammer. Tool speed and impact force can be adjusted electronically to match the processed material.
Rotary hammers are divided up by weight into these categories:
Light rotary hammers weigh from 1.8 to 3.0 kg, medium hammers from 4 to 5 kg, and heavy hammers from 6 to 12 kg.
The universal motor powers an electro-pneumatic, low-vibration hammer mechanism which in turn is energised by an enclosed, pressurised and elastic air-cushion which ensures that the impact force remains constant. Light rotary hammers owe their low-vibration and noise reduced running to a flywheel transducer and a slipper piston. Medium and heavy rotary hammers utilise a conventional crank drive. Light rotary hammers of the latest generation are equipped with electro-mechanical striking mechanisms. In general, rotary hammers are used in their combined rotation/hammer function. Rotation can be switched off for slot-cutting or chiseling applications, or it is switched off automatically by the special shape of the chisel shank. This is called rotation stop.
