Product Description

Surface of cone back and cutters are hard enhanced by high wear resistance tungsten carbide,largely increase the work life of bit.

Optimal cutter rows,cutter quantity,cutter length and cutter structure design largely improve the drilling capability and speed.

Widely used in oil exploration,mining prospecting,subterranean heat ,hydrology etc.
