Abstract

1506239 Drill bits UGINE ACIERS 23 May 1975 [12 June 1974] 22595/75 Heading B4C [Also in Division E1] A cutting tip 1 for drilling rock by means of down-hole hammer drill comprises a body 2 which has a working face 3 provided with studs 4, and a tail 5 for mounting in a drill socket 6, the latter having bores 7 for introducing gas under pressure. The trailing end of the body 2 opposite the working face and adjacent the socket 6, is formed with peripheral recesses 9 situated in the extended path of the socket bores 7 and directing part of the gas supply on to the periphery 10 of the cutting tip. At least one bore 11 extends in the body 2 from each recess 9, obliquely of the longitudinal axis 12 of the cutting tip, to emerge at the working face 3, so directing the remainder of the gas supply on to the working face.
