Abstract

707,747. Drills. HONNEKNOVEL, G., [trading as HONNEKNOVEL, F. A. [Firm of]]. May 23, 1951 [Nov. 15, 1948], No. 12097/51. Class 83 (3). [Also in Group XXIII] A cutting tool comprises a helically twisted steel rod which has a rectangular cross-section, the longer sides of which are at least double the length of the shorter sides, and which has a row of pyramidic teeth 2 on each of its edges, the twisting providing two deep channels 1 for chips. The end 4 may be formed as an auger, a point, or a centre, or other form of, bit. The diameter of the end is equal to, or larger than, that of the remainder of the tool. Specification 428,675 is referred to.
