Metal Sealed Bearing Tri-cone Bits
----Cutting Structure
Steel Tooth: Premium tungsten carbide hard facing on the surface, it's greatly enhance the wear resistance of the tooth.
Tungsten Carbide Inserts: Various type high quality tungsten carbide inserts can
Be equipped on the bits, professional and scientific selection of the inserts as per
The different application and drilling process so that to achieve high efficient drilling production.
----Gauge Structure
Multiple gauge protection with gauge trimmers on 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
Journal bearing and roller bearing types are available to be chosen. Abrasion & seizure resistance, loading capacity, stability of the bearing are well improved, suitable for high speed rotary drilling.
----Seals and Lubrication
The advanced metal seals improve the reliability and stability of the bearing sealing. Pressure difference type compensating system assures a good greasing lubrication function.
---- IADC vary from 117--637 applicable for different type formation.

----Seals and Lubrication
Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance. Pressure difference type compensating system assures a good greasing lubrication function.
---- IADC vary from 114--637 applicable for different type formation and different drilling rotary speed.
Non-Sealed Roller Bearing Tri-cone Bits
----Cutting Structure
Steel Tooth: Premium tungsten carbide hard facing on the surface, greatly enhance the wear resistance of the tooth.
----Bearing Structure
Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling;
Balls lock the cone which reduces the probability of cone dropping to minimum
---- IADC vary from 114--321 applicable for the hole drilling in the upper section
With good drillability.
Air Cooling Roller Bearing Tri-cone Bits
----Cutting Structure
Tungsten Carbide Inserts: Various type high quality tungsten carbide inserts can be equipped on the bits, professional and scientific selection of the inserts as per the different application and drilling process to achieve high efficient drilling production.
----Gauge Structure
Multiple gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability.
----Bearing Structure
Air cooling roller bearing package. Balls lock the cone, which reduces the probability of cone-dropping to minimum.
---- IADC vary from 512--732 applicable for mining.
