BITS

Cone-type Rock Bit.

A cone-type bit has three (3) cones, a forged steel body and a cone axle or pin which forms part of the body. The cones have roller bearings fitted at the time of assembly. The shape of the cutting surfaces and the design of the teeth are varied to drill in a variety of formations. Some have inter-fitting or self-cleaning teeth. All cutting surfaces are flushed or cleaned by the circulating fluid.
