Product Description

tricone drillbit/ rock bit/small water well drilling machine with many IADC codes

1. Specifications of our products:

TCI bits

1,Soft formations(**7,**7,**7,**7)

Features large chisel-shaped inserts to provide the highest penetration rate in the softest formations such as shales, clays, limestone and sands. 

2,Soft to medium formations(**7,**7)Designed to drill effectively in formations such as hard limestone, dolomite, hard sands, and other formations with hard cherty.

3,Medium to hard formations(**7)

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(******7)

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(**1,**4,**6,**4,**6,**7)

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(**3,**4,**5,**7)

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

3. 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.
