Abstract
193,679. Tucker, A. M. Feb. 28, 1922. Bore-hole apparatus.-In a rotary drill, a cutter 5 is rotatably held on a bushing 4 by a threaded collar 13 and the cutter, bushing and collar are provided with apertures whereby they may be locked together by means of a pin 18 to facilitate attachment of the bushing to a threaded spindle 1 carried by the drill stem 2. The apertures in the cutter and collar are afterwards closed by a set-screw 25. Lubricating ports 21, 23 are provided.
