Product Features

1. Cutting Structure of this series tricone rock bit :
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
2. Gauge Structure of this series tricone rock bit :
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.
3.Bearing Structure of this series tricone rock bit :
High precision bearing with two thrust faces. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.
4.Seal and Lubrication of this series tricone rock bit :
The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal 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.
5.Product Application of this series tricone rock bit :
It is suitable for downhole motor and high speed applications.

Description of tricone bit

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.

vary from 512--732 applicable for mining.

The Advantages of using a tri cone over other drill bits

There is a tri cone suitable for any rock formation

Tri cone bits are versatile and can handle changing formations
Tri cones Are reasonably priced with long life and good rate of drilling
Depending on your application we can provide you with new, re-run or premium oil field quality tricone bits. The difference between a premium oil field tricone bit and non-premium oil well quality tricone is that the roller cones have high end sealed bearings; extremely high quality tungsten carbide and offer diamond gauge protection throughout the drill bit as well as skirt tail hard facing and optimized hydraulics. These roller cone drill bits are designed to go to extreme depths in extreme conditions and in situations where they cannot fail.
When Ordering a bit the IADC bit classification system is a very useful tool and allows us to specify a bit that out preform your expectations.
Our TCI tricones bits Range in size from 3.875” (88.9mm) to 28” (711.2mm)
