Abstract
593,622. Drills. GULLICK, Ltd., and SEAMAN, T. Nov. 8, 1944, No. 21905. [Class 83 (iii)] In a drill bit or like cutting tool having one or more radially disposed cutting elements 10, 11 the tips 16, of tungsten carbide, are recessed into the body 15 and secured by brazing or the tike. The cutting edges 17, 18 are of angular, inclined, or curved shape and the tips have base edges 19, 21 of similar shape to allow the edges to be sharpened to their limit without waste. The shank 12 can be secured to a drill rod by a transverse pin through a hole 14. Specification 592,086 is referred to in the Provisional Specification.
