8 inch steel tooth tricone bit water well drilling bit
Samples:IADC 116 117 126 127 136 137 216 217
$890.00/Piece | 1 Piece (Min. Order)
Main Features
1) Tci tricone Bit Connection made according to API standard.
2) We can adjust the bit size according to your rig.
3) The best result can be obtained by using the steel-tooth bit in the soft stratum. If mining in hard formation, TCI tricone bit is recommended. Apply to Construction, Water Drilling, Mining, Horizontal Directional Drilling, Geothermal and Environ-mental.
