special type PDC

Spherical PDC

Mainly for small and medium sized button bit, DTH bit, can also for roller cone bit for petroleum drilling. It has good wear ability and better impact toughness, available for percussion drilling.

Conical PDC

Mainly used for gage protection or as drilling teeth of mono-cone bit for petroleum drilling. It can also be used for DTH bit requiring high efficiency.

Wedge PDC

Used for gauge protection or as drilling teeth of tri-cone bit for petroleum drilling.
