formations such as shales, clays, limestone and sands. 

2,Soft to medium formations(617,637)

Designed to drill effectively in formations such as hard limestone, dolomite, hard sands, and other

 formations with hard cherty.

3,Medium to hard formations(737)

For extremely hard formations such as chert, granite, flint, and taconite. Features short, 

closely-spaced inserts to ensure maximum penetration rate and wear resistance

Milled tooth bits

1,Soft formations(114-117)

These bits are designed to drill the softest formations such as soft shales,red beds, and clays, 

 with high durability and maximum penetration rates. 

2,Soft to medium formations(121,124,126,134,136,137)

These bits are designed to drill formations such as shales, medium soft limestone, Medium 

sandstone and other formations with intermittent hard streaks. 

3,Medium to hard formations(213,214,215,217)

These bits are designed to drill formations such as hard sandstone, dolomite, and broken 

formations with hard cherty streaks

Main features

1. Cutting Structure of this type sealed and non-sealed tci tricone bits :

The wear-resistance of teeth is enhanced with premium tungsten carbide hard facing on the tooth 

surfaces for steel tooth bit. 

2. Gauge Structure of this type tci tricone rock bits:

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.

3. Bearing Structure of this type tci tricone rock bits :

High precision roller bearing with two thrust faces. Ball locks the cone. Thrust faces hard face with

wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved. 

Metal Sealed Bearing Tricone Bit

----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.
