We are a professional company in supplying tricone bits,steel teeth bits,single cone bits,and PDC bits. Bits sizes range from 3 7/8" to 26".and cover almost all IADC codes.It can be used in various of different fields,mining,hydrology,subterranean heatpilling,water well drilling and oil well drilling.This type of bits have optimal bearing design, it can be working stably in high WOB,and the qualtiy tungsten carbide inserts on cone and the gauge make a good wear resistance largely extend the working life of bits.It is suitable for medium  to hard formation.
