PDC inserts are made by sintering diamond grains and cemented carbide under high temperature and high pressure, which has not only diamond’s high wear resistance but also cemented carbide’s high strength. This product is widely used in roller cone bits, down-the-hole drill bits, picks, crushing machinery and other fields, the best substitute for carbide teeth.
PDC inserts have a few different shapes, such as dome-shaped inserts, flat-top inserts, conical-shaped inserts, chisel-shaped inserts, etc.
PDC inserts adopt the transition layer technology between the diamond layer and the cemented carbide layer, which has outstanding impact and ultra-high wear resistance, making it widely used in high-end PDC drill bits, such as shock-absorbing teeth, center teeth, gauge protection teeth, etc.
