Abstract (en)

The invention concerns a method of mounting a cutting insert (22), such as a studcutter, in the working face (12) of an abrasive tool, such as a drill bit. In the method an externally threaded plug (16), formed with a recess (18) therein, is screwed into a complementally threaded socket (14) in the working face. The cutting insert (22) is secured in the recess (18) in the plug (16). The cutting insert (22) has a transversely extending formation (20B) which locates in an undercut (18B) in the recess (18) in the plug with a gap between the formation and the recess. A locking insert (32) is located in the gap in such a manner as to anchor the cutting insert relative to the plug. The locking insert is typically of malleable material and is deformed into the gap. <IMAGE>
