Abstract

957,288. Percussive drills. A FISCHER. April 9, 1963 [April 24, 1962], No. 14148/63. Heading B4C. A percussive boring tool comprises a bit 1 detachably mounted in a holder 3 by means of a bayonet joint, the slot 2 and pin 4 of the joint being formed either in the bit or holder. The slot, which is in the form of a depression in a tubular bit, is provided with a slightly-inclined portion 2a so that when the bit is inserted into a bore 3a in the holder and then rotated, the bit is locked firmly therein. In a modification, the pin may be in the bit and the slot in the holder.
