Product  Feature

1.Tricone Bit, Steel Tooth Bit, TCI Bit, Single Cone Bit,Tricone Rock Bits,Rotary Bits

Application Petroleum & Gas ,Water well ,Mining and Tectonic Industries ,Oil field, Construction, Geothermal, Directional Boring, and Underground Foundation work.

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 hard facing 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 hard facing 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.

6.Main Availability

TCI Tricone bits

TCI 437 Soft formation TCI Tricone bits

The 437 tci bits are used to drill low compressive strength very soft formation tci bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design combined with maximum cone offset ,results in high bit penetration rates.the deep intermesh of cutter rows prevents bit bailing in sticky formations.

TCI 517   medium formation TCI Tricone bits

The 517 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows this design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations the HSN rubber o-ring provides adequate sealing for bearing durability.

TCI 637    can be used to drill hard and abrasive formations .wear –resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge.maximum numbers of hemispherical-shaped inserts are used in all rows to provide cutter durability and long life.

TCI 617  the TCI tricone bits 617 features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows .this design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations . the HSN rubber o-rin provides adequate sealing for bearing durability .
