Abstract
452,050. Percussive drills. LIDDICOAT, P., Timmins, Ontario, Canada. Feb. 16, 1935, No. 5115. Convention date, Feb. 17, 1934. [Class 124] The bit 4 is formed with an angular or oval recess to receive the shaped end of the drill steel 1. Lugs 14, 15, 16 on the steel deform the edge 19 of the recess and press it into a recess 18, thus attaching the bit to the steel. The recess in the bit has a partially concave bottom 10. The cutting edges of the bit are cruciform.
