Abstract

1,112,446. Percussive tools. TUNGSTEN CARBIDE DEVELOPMENTS Ltd. 16 Aug., 1966 [18 Aug., 1965], No. 35347/65. Heading B4C. [Also in Division B3] A hard metal tip 9 is secured by forging within a blind bore 5 in the end of a tool such as a coal-cutter pick. The tip is preferably of tungsten carbide and may be of circular or square cross-section with a conical or pyramidal point 16. The steel nose 1 of the pick has a bore of the same diameter as a shoulder 12 on the tip which preferably has longitudinal grooves 11; the grooves 11 may, however, be omitted, Fig. 3 (not shown). The forging is performed hot.
