What is the difference between Rotary Hammer bits and Rotary/Percussion bits?
Rotary/Percussion is used in light duty applications. The speed range is 1300-3500 rpm at up to 50,000 blows per minute (bpm). The impacting action created by the drill motor fractures the concrete into tiny granules. Rotary Hammer Bits turn much slower (400-1000 rpm, 4500 bpm) and hit much harder than Rotary/Percussion. Generally, hammer bits cut much faster than percussion bits.
