PDC is mainly applicable for PDC drilling bit for drilling into soft and intermediate-hardness stratum.
PDC drilling bit made of such PDC will break up rocks depending on shearing action when it works, which is more effective than crushing of rocks by roller cone bit or plowing and grinding of rocks by diamond impregnated bit. The serrate structure combination between polycrystalline diamond layer and hard alloy substrate allows more fixed combination between the twe layers and allows more impact resistance of the whole PDC. There are kinds of serrate forms for selection by clients, and special tailoring is also available accorrding to client's requirement.
