Hammer rely on the rotation and Strickland call work. A single beat is very high, and has 1000 per minute to 3000 beat frequency, can produce significant force. Compared with the impact drill, electric hammer needs a minimum pressure to drill into hard materials, such as stone and concrete; especially the relatively hard concrete.
