Key features

Concave face design concentrates impact energy at the center, delivering efficient rock breaking in hard water well formations.

Stop poor ROP in hard interbedded formations; centralized cutting action prevents bit wandering and ensures straight boreholes.

Field tests show 30% faster penetration in quartzite and basalt compared to standard flat face PDC bits.

Ideal for deep water wells, geothermal wells, and hard rock mining applications.

Reinforced center cutters withstand high impact loads, reducing tip breakage by 35% in extreme conditions.

Product Q&A

Q:What makes concave PDC bits better for well drilling?

The concave shape focuses weight and impact energy at the center, improving cutting efficiency in hard rock formations.

Q:Can this bit handle fractured and broken formations?

Yes, the reinforced center design and matrix body provide excellent impact resistance in fractured ground.

Q:What is the recommended rotation speed for hard rock well drilling?

For hard rock applications, we recommend 40-60 RPM. Slower speeds help protect cutters from impact damage.
