Abstract

516,507. Percussive drills. HOLMAN BROS., Ltd., and HOLMAN, A. T. July 26, 1938, No. 22179. [Class 124] Rock drills, particularly high speed rotary drills with diamond or like bits are provided with steadying means for the drill in. the form of a spiking screw bar 21 or the like exciting a reaction on the drill cradle 18 or its support.
