ABSTRACT:
A drill chuck for holding a tapered end of a tubular drill bit. The chuck comprises a driving member having a tapered surface for frictional engagement with the tapered end of the drill bit, a first holding member mounted on the driving member and a second holding member mounted, in use, on the tubular drill bit. The second member has a substantially radial surface thereon for abutment with a surface 31 on the drill bit. The two holding members can be screwed together whereby abutment between the substantially radial surface on the second holding member and the surface on the drill bit urges the tapered end of the tubular drill bit into frictional driving contact with the tapered surface of the driving member.
