Advantage of steel tooth tricone bit: 1>Higher penetration rate. The longer teeth has faster drilling down speed. 2>Anti-balling. The sticky rocks always make bit-balling, steel tooth tricone bit is suitable for drilling soft formations and sticky rocks. 3>IADC127 has tungsten carbide inserts on gauge of cones, this feature is well to avoid diameter-shrinkage.
