Tri Cone Drill Bit Feature
Cutting Structure
The wear-resistance of the teeth is enhanced with premium tungsten
carbide hard facing on the tooth surfaces for the steel tooth bit.
The durability of premium tungsten carbide inserts is improved with
new formulas and new techniques for insert bit
Gauge Structure
Multiple gague protection with gauge trimmers on the heel and gauge
inserts on the gauge surface of the cone, tungsten carbide inserts
and hard facing on the shirttail increases gauge holding capacity
and bearing life.
Bearing Structure
High precision journal bearing with two thrust faces, Balls lock
the cone. Hard faced head bearing surface. Cone bearing inlaid with
friction-reducing alloy and then silver-plated. Abrasion resistance
and seizure of the bearing are improved. and suitable for high
rotary speed
Seal and Lubrication
The advanced metal seal package consists of two metal seals and two
elastic energizers. Compressed energizers ensure good contact being
kept on two sealing surfaces of metal rings by elastic force, and
achieves the bearing seal. In the drilling, metal seals are
relatively dynamic, and the energizers are static. This will
improve the reliability and durability of bearing seal. The
pressure compensator system and advanced grease can greatly
increase the lubricating reliability.
Tri Cone Drill Bit Application
It is suitable for down hole motor and high speed applications
Main features
- The wear-resistance of teeth is enhanced with premium tungsten
carbide hard facing on the tooth surfaces for steel tooth bit.
- High precision roller bearing with two thrust faces. Ball lock the
cone. Thrust faces hard-face with wear resistant alloy. Abrasion
resistance and seizure resistance of the bearing are improved.
- Multiple gauge protection with gauge trimmers on the heel and gauge
inserts on the gauge surface of the cone, tungsten carbide inserts
and hard-facing on the shirttail increases gauge holding capability
and bearing life.
