Introduction:
Design for higher ROP in drilling deeper and harder formations, PDC drill bit always drills from ground to bottom directly with less or even a single run, saving large amount of drill time and cost .
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.

Features:
PDC Cutters
Different features of PDC cutters can be chosen in different wells or formations for maximizing 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
