Product Description

Downhole tools for petroleum-equipment-machinery 12-1/4" Strong Rock-Breaking Oil Drill Bits

Our oil bit adopts a double-row composite piece, which increases the shear force of the bit while sharing the fatigue wear of the front row of the composite piece. This strengthens the wear-resistant degree at the diameter-retaining place. The crown adopts a parabolic structure, which greatly improves the footage in the drilling process.
