6 3/4 inch steel tooth tricone roller bits
Samples:IADC 116 117 126
$660.00/Piece | 1 Piece (Min. Order)
steel tooth bit is one of the main tools for blast hole and water well drilling. Its life span and performance whether suitable for drilling or not, that has an great influence about the quality, speed and cost of drilling project. The rock breakage by the steel tooth bit which used in mine is working with both the impact of teeth and the shear caused by slippage of the teeth, which bring high rock breaking efficiency and the low operation cost.
