Drill speed impact drill, electric hammer is how much?
Hammer and hammer drill with the similarities and differences between rotation, particularly suited to the needs of small force materials such as drilling, cork, metal, brick, tile etc.. 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.
Percussive drills work by rotating and impacting. A single shock is very slight, but a shock frequency of more than 40000 minutes per minute can produce continuous force.
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.
