tricone drill bit,
tricone rock roller bits
High strength high wear resistance carbide water well drilling 6.5'' TCI tricone drill bit for hard rock drilling
Rolling cutter bits, which some may also call roller cone bits or tri-cone bits, have three cones. Each cone can be rotated individually when the drill string rotates the body of the bit. The cones have roller bearings fitted at the time of assembly. The rolling cutting bits can be used to drill any formations if the proper cutter, bearing, and nozzle are selected.
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.
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
High precision roller bearing with two thrust faces. Ball lock the cone.Thrust faces hardface with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.
Seal and Lubrication
Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
