PDC
(Polycrystalline diamond) is
manufactured by sintering diamond particles and cemented carbide substrate
at high temperature and super high pressure.
PDC-P (for petroleum drilling)
and PDC-M (for mining) series are separately supplied to meet different
user's demand.

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.
