Product Description
Differ from tricone bit, PDC drill bit runs with lower WOB but Higher RPM, so it usually works with downhole motor to pick up rotating speed.
The performance of PDC drill bit depends a lot on PDC cutters, we provide unique solution to specific requirement on varied formations.
Steel Body PDC Drill Bit obtains better ROP in soft to medium hard formations and lower compressive strength.

Cutters
PDC cutter technology made a perfect performance on impact strength resistance and abrasive resistance.
Arc-surface PDC protection made the gauge more abrasion resistance and more radial vibration resistance than the TSP protection.Different features of PDC cutters can be chosen in different wells or formations for both drill efficiency and economic
Gauge length
Short:Improved bit steerability and tool face control for directional or horizontal drilling, reduce slide section by achieve builds more quickly.
Extend:Enhances bit stability and allows more area for gauge protection components, improves bole hole quality.
Active gauge
Protect the gauge and improved hole quality.
