摘要 |
An abrasive tool such as a drill bit has a body with a working face (10). Undercut recesses (12) are formed in the working face (10). Cutting inserts (16) which present working ends (20) are located in the recesses (12). Locking means (24) in the recesses engage between the undercuts (14) and formations (22) on the inserts (16). This locks the inserts (16) against withdrawal from the recesses (12). <IMAGE> |
