Abstract

1,095,022. Percussive drills. A. FISCHER. March 2, 1965 [March 6, 1964; June 15, 1964; Aug. 1, 1964], No. 8978/65. Heading B4C. [Also in Division F2] A drill bit for a percussion tool is formed by rolling a blank, Fig. 3, to form a hollow tube with a longitudinal slit while leaving a lug 1a extending tangentially for locking in a bit holder of the tool. There may be threads impressed on the blank so that the drill bit has an internal screw-thread 2a, Fig. 5, and acts as a screw-socket after it is anchored in the bore and its driven end 1b is broken off at a weakened part defined by a groove 4b joining notches 4. For anchoring, the cutting end 3 is spread by a conical nut, Fig. 2a (not shown), inserted in the cutting end 3 after withdrawal of the bit from the bore and before its re-introduction, or by a cylindrical nut 5 (driven in without withdrawing the bit) used if there are internal projections 3b formed in the cutting end. One flank of each notch 4 is elongated to act as a depth indicator when drilling. A bolt or threaded shank of a hook is screwed into the anchored drill bit or a smaller such member is screwed into the thread of the conical nut or cylindrical nut 5. The slit (33c), Figs. 10, 11 (not shown), may be very narrow (at 33b) in the region of the internal thread (32a).
