Abstract

690,905. Making drills. HEIDEN, A. L VAN DER, and BUECHLER, E. G., [trading as A. G. F. KNOPENFABRIEK]. Oct. 1, 1951 [Oct. 20, 1950], No. 22851/51. Classes 83 (ii) and 83 (iii). Annular cutters.-In a method of making crown drills, cylindrical inserts 4 of hard metal such as tungsten carbide are brazed in a ring of holes 3 in a cylindrical blank 1 which is then machined to produce a thin wall 2 and teeth 5, the axes of the inserts being substantially coincident with the middle of the wall.
