Abstract
Improvements introduced in rotary percussion bits, said improvements characterized in that they comprise a body provided with a longitudinal axis and an end face; insert cutting accessories mounted on the body and projecting axially forward from the end face; each accessory having a substantially flat front or attack face that lies substantially in a plane that extends parallel to the longitudinal axis to form an angle of incidence of practically zero, all said front or attack faces being similarly oriented to face each other in the intended direction of bit rotation; and wherein each of said front or leading faces project axially forward of the end face of the body to communicate at a leading or leading cutting edge with a face of separation from its inserted accessory, face of separation which is it extends practically transversely to the bit, the arrangement being such that during the rotary and percussive drilling action, the wear tends to take place on the parting face and thus the leading cutting edge tends to be protected.
