A hammer drill, also known as a rotary hammer, roto-drill or hammering drill, (see also rotary drill) is a rotary drill with a hammering action. The hammering action provides a short, rapid hammer thrust to pulverize relatively brittle material and provide quicker drilling with less effort.
The following tests: roto bar, mechanical, warpage, and machinability are performed at the manufacturing level, prior to keying the shaft, to ensure proper product performance in the field.
