TCI tricone button roller bits

1. Metal-face sealed bearing TCI button roller bits

Cutting Structure

The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert 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.

Sealed Bearing Structure

1.Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.
2.The advanced metal seal package will improve the reliability and durability of bearing seal.

Main

IADC Code:4-- Series, 5-- Series, 6-- Series,etc.

2. Elastomer sealed bearing TCI button roller bits

Cutting Structure

The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit.The Tricone bit field is composed of a shallow sequence of sediments of

fluvial origin, in which sandstone channels contain heavy oil with gravity ranging from 11 to 13°

Gauge Structure

Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and

hardfacing on the shirttail increases gauge holding capability and bearing life.

Sealed Bearing Structure

1.Abrasion resistance and seizure resistance of the bearing are improved.
2.Premium O-ring, Optimal seal compression and curved seal structure can enhance the

seal performance.

Main Type Available

Size: 5 7/8",6",6 1/2",7 1/2",7 7/8",8 1/2",9 1/2",9 5/8",9 7/8",12 1/4",14 3/4",17 1/2", etc.

3. Air Cooling Roller Bearing TCI button roller bits

Cutting Structure

The durability of premium tungsten carbide insert is improved with new formulas and

new techniques and new techniques.

Gauge Structure

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 conewhich reduces the probability of

cone-dropping to minimum.The HH Tricone bit Series reduces sound to a maximum of 60

decibels at the location limit, compared to conventional rigs where sound averages up to 120 decibels.

4. Non-Sealed Roller Bearing TCI button roller bits

Cutting Structure

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 hard facing on the tooth surfaces for steel tooth bit.

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 Cdropping to minimum.

Main Type Available

The size range of this series bit is 14 3/4 -26 inch and its IADC code is 111-241.
