Abstract
1,181,428. Boring earth &c. PADLEY & VENABLES Ltd. 13 Nov., 1968 [28 Nov., 1967], No. 54046/67. Heading E1F. A bit comprising a head 1 having cutting inserts 11a, 13a and a shank 2, has flushing fluid passages such as 16, 17 opening into the working surface 6 of the head and the shoulder 3 between the head and shank. The shank is adapted to be housed in the casing of a percussive "down-the-hole" drill 100 which is continuously or intermittently rotated. When positioned in the drill the shank is struck by the drill hammer 104, and the passages are connected to the exhaust ducts 107 of the drill, the air or water driving the drill thus acting as the flushing fluid. The rear outer part of the head may be formed by a rubber or nylon sleeve bonded to the rest of the head. Specification 995,599 is referred to.
