Tricone Bit
Products Introduction:
Jayalakshmi tricone bit covers almost IADC code, including 11 common types, and is with reliable quality and reasonable price, the size range is from 3 7/8’’ to 26’, can be used for geological prospecting, development of oil and gas,
drilling water wells, blast holes and making holes for seismic prospecting, construction engineering.
The Classify of tricone bits/roller bits:
Steel teeth series: (IADC CODE: 116, 117, 126, 127, 136, 137, 216, 217, 317, 337)
TCI series: (IADC CODE: 417, 437, 447, 517, 527, 537, 547, 617, 627, 637, 647, 737, 837)
USES:
High quality top tricone bit tools, which are widely use in mines, quarries, earthworks and other
engineering drilling blasting hole, guardrail hole, mountain reinforcement, anchorage and other engineering holes, geothermal
exploration hole, well bore and other fields.
