Wholesale API customized tricone rock bit in stock based on the lowest quotation and excellent quality for deep well drilling.
1) Drill 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.
4) Proven cutting structures and bearing designs continue to deliver a superior level of performance and reliability.
5) Optimized hydraulics provide increased ROP by efficiently removing cuttings and ensuring engagement of new rock on every cutting structure rotation.

14 3/4" is the regular size which widely use thd drilling projects.
Steel tooth tricone bits have another name milled tooth tricone bit since the teeth are produced by milling machine, the cone surface is hard-faced by tungsten carbide.
The steel tooth tricone bits has longer teeth than TCI tricone bits so that it can drill soft formations at high ROP.
In oil drilling projects, the ROP could reach 30 meters per hour in shallow section drilling.
