摘要： An adapter is provided for presenting a diamond composite, such as a TSDC, which is bonded therein by a metal matrix composite material. The adapter body is suitable to be received in a complimentary mount formed on a wear face of a wear tool. The approach described allows for machining of individual adapters to provide a precise fit within the wear tool mount without the need for challenging machining of the diamond composite or overcoming the difficulties in precisely bonding multiple diamond composites into their complimentary mounts.
