PDC Bit Non Core Steel Drilling Bits with 3wings for Mining Industry
PDC Drill Bit Feature:
1. Suitable for soft, medium and hard formations.
2. Super strong material promotes gauge wear resistance to provide
long bit life.
3. PDC cutter can improve the life and shield the risk of complex
formation drill not passed.
4. Drilling dynamic equilibrium design and hydraulic balance design
make the drilling process more smooth
