Cutting Structure
Steel Tooth: Premium tungsten carbide hard facing on the surface,
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 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 114--637 applicable for the hole drilling in the upper section with good drillability.
