High strength high wear resistance carbide water well drilling
6.5'' TCI tricone drill bit for hard rock drilling
Application
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.
Characteristics
Cutting Structure
The wear-resistance of teeth is enhanced with premium tungsten
carbide hardfacing on the tooth surfaces for steel tooth bit.
Gauge Structure
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.
Bearing Structure
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.
