PDC Drill Bits
1. Description
PDC (Polycrystalline Diamond Compact) bits deliver exceptional performance in soft to medium-hard formations, offering faster ROP (Rate of Penetration) and longer service life compared to conventional drill bits.
Key Features:
✔ Diamond-Enhanced Cutters – Premium PDC cutters provide unmatched abrasion resistance for extended bit life.
✔ Optimized Hydraulics – Advanced nozzle placement improves cuttings removal and cooling efficiency.
✔ Customizable Designs – Available in matrix or steel body types with various blade/cone configurations for different formations.
✔ Stable & Vibration-Resistant – Anti-whirl design reduces lateral movement for smoother drilling.
✔ Cost-Effective Performance – Higher drilling speeds reduce operational time and overall project costs.
Ideal for oil & gas, geothermal, and water well drilling. Request custom engineering support for your specific formation challenges.

3.Recommended Rock Formation
soft to medium formation with lower compressive strength and good drillability,such as marl,shale,lignite,sandstone,anhydrite,tuff ,etc.
4.Working Principle of PDC Drilling Bits
Drilling PDC drilling bit breaks rocks by cutting. The self-sharpening cutting teeth can easily cut into the formation under the action of WOB and move the shear rock forward under the action of torque. When multiple PDC cutting teeth work at the same time, and there are many free faces of the bottom rock, the rock is easy to be broken under the shear action. That's way PDC drilling bit has higher rock-breaking efficiency ans faster drilling speed.
