PDC drill bit
Fixed cutter polycrystalline diamond compact (PDC) drill bits are an integral part of the driller’s toolkit, yet can still vary widely in terms of stability, ROP and effectiveness in hard and abrasive formations.

Tercel provides a broad portfolio of fixed cutter bits for all environments including: bits targeted at rotary steerable and steerable motor applications; large diameter bits designed for surface hole and soft shallow formations; and fixed cutter bits for all other uses. A highly spiral design for improved lateral and torsional stability or cutting structure reinforcement is also available. The result is enhanced stability, steerability and directional response —delivering optimized penetration rates, reduced vibration and improved toolface control.
