Abstract

955,410. Making drills. A. FISCHER. May 9, 1960 [May 8, 1959; May 26, 1959], No. 25904/63. Divided out of and addition to 954,020. Headings B3A and B3C. A wall-boring bit comprises a blank, complete with cutting-edges at each end, punched out from a steel plate. The blank 1 is formed into a hexagonal or circular bit 4. A sliding plastic insert is provided to prevent deformation of an end of the bit when held in a chuck. A tang 6, which prevents slipping of the bit during drilling projects through a slot 7 allowing the escape of cuttings.
