130mm Tricone Cone Cutters/Single Cone Cutters for Hole Opener

Specifications about our tricone bit

TCI bits

1,Soft formations(417,437,517,537)

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(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. 

1.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 hardfacing on the tooth surfaces for steel tooth bit.

2. 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.

3.BEARING STRUCTURE

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

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.
