Abstract

423,647. Stone drills. MEUTSCH, A., and GEWERKSCHAFT WALLRAM, 96, Kruppstrasse, Essen, Germany. May 25, 1934, No. 15604. [Class 124] [See also Group XXII] A stone drill, either for percussive or rotary drilling, has a hardened cutter 4 inserted in a slot in the end of the drill stem, this cutter being supported on both faces by the parts 18, 11, of the stem. The faces of the cutter have grooves 18 to receive brazing material. In a modification, the bottom of the slot is curved. In a further modification, three cutters are inserted, one or two of which do not extend to the axis of the drill.
