Abstract

1276249 Boring earth MISSION MFG CO 16 Feb 1970 [24 Feb 1969] 7417/70 Heading E1F A rotary percussive bit has a bottom surface C carrying cutting elements 23, with at least a portion 11 being inclined to the axes of the bit and having cutting elements 20 asymmetrically arranged with respect to the bit axis to provide a lateral thrust on the bit in use. Further cutting elements 27 are provided on that side of the bit which is thrusted towards the side of the bore-hole so that a hole slightly larger than the bit is bored. Portion 11 may be a conical recess as shown or a conical projection or a frusto-conical portion around the periphery of the bit.
