Tricone bits are available in new steel tooth and tungsten carbide insert, size from 3 3/8"(85.7mm)to 26"(660.4mm) for use in all formations, with any bearing/seal type, and a wide range of additional custom features.Tricone bit, are widely used in mining, oil well, water well, thermal drilling.
Tricone bit Included Steel Tooth (also referred to as milled tooth) bits and Tungsten Carbide Insert (TCI) bits,TCI bits are much more durable than Steel Tooth ones, but carry a higher cost to manufacture.
