PDC Carbide Plate For Oil Gas Drilling Bits Carbide Metal Working
Carbide Thin Round Disc
PDC cemented carbide discs are used for petroleum exploration and
drilling of oil wells in oil fields. Due to the higher hardness and
wear resistance of PDC, the efficiency of drilling is greatly
improved.
The diameter of our PDC alloy disc substrate is 4.5-20mm, the
thickness can be from 0.6-4mm, and the single side can be polished.
Recommended grades for drilling:
