2) PDC bits have much longer using lifetime;

3) PDC bits have repair ability.


    The Diamond PDC drill bit designed to run at high penetration rates even in applications that call for higher blade and cutter counts. Its unique cutting structure layout adds another dimension to bit stability and smooth running by combining the penetration rate potential of traditional "single set" cutter layouts with the life extending features of a "plural set" cutter layout.



Features of PDC Bits:

1) Force balanced, resist impact to the balde during high-speed drilling, to make bit work stable.

2) Plus wear knot section, reduce collision in the high-speed rotational vibration.

3) Patented matrix formulation, extend bit life.

4) Optimal hydraulic design, easy to move out the drill cuttings and cooling.

5) Equipped with back reaming teeth.

6) The cutter is high performance to increase the ability of anti-impact and anti-abrasive.
