Abstract

203,039. Swanton, F. V. W. May 30, 1922. Percussive drills.-A detachable threecornered bit 5<a> is held in a split socket 27 screwed into the end of the drill bar. A flat-ended guide-member 22 also fits into the holder and is held in place by a recess 24 through which the bit passes. In place of the member 22 two short bits may be used, one on each side of the bit 5a, making a cruciform cutter. The section of the bit is an equilateral triangle with the corners bevelled to 90‹.
