5 7/8 inch IADC 417 steel tooth drill bit

Samples:IADC 417

$870.00/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.
