Mining Bit / 9 7/8 IADC 645 Tricone Bit / Rock Drilling Bit

Cutting Structure

Tungsten Carbide Inserts: Various type high quality tungsten carbide inserts can be equipped on the bits, professional and scientific selection of the inserts as per the different application and drilling process to achieve high efficient drilling production.

Gauge Structure 

Multiple gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability.

Bearing Structure 

Air cooling roller bearing package. Balls lock the cone, which reduces the probability of cone-dropping to minimum.
