This practical and new-style through optimizing interfacial structure and the design that increase inclined cut, increased to get together brilliant diamond layer and hard alloy the osculatory area between, dispersed the leftover stress on the interface, the wearability that improved a product, fight concussion tenacity and be able to bear or endure erosive function, special agree with of broach of PDC of deep-sea oil gas make. : of dominion benefit requirement? The diamond of broach of DC of Ting of S of Li of extensive bell rotten expostulate with is compound piece, you Jujing diamond layer (1) with hard alloy matrix (2) two parts composition, its feature depends on: What narrate hard alloy matrix (2) on the setting on end panel has a certain number of table structure, table structure by appearance identical raised (4) and cave (5) composition, hard alloy matrix (2) the setting on flank has inclined cut (6) , get together brilliant diamond layer (1) on flank with inclined cut (6) corresponding place setting has with inclined cut (6) complementary inclined protruding stage (7) .
