TCI Tricone Bits IADC 545 in sizes from 7 7/8" to 12 1/4"

Product Details

(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 hardfacing 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 hardfacing 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.

What is Blast Hole Drill Bits?

​In the mining industrial, blast hole drilling is very important to achieving the required product or outcome. Drilling suitable holes allowing explosive charges to be placed down the holes. And then to blast large areas making them more manageable and easier to remove.

Bits thread are manufactured according to API standards.

Advantage:advantage of tci drill bit

1. Rotary drill bits are manufactured using aircraft quality steel and premium carbide grades developed to suit the toughest application.
2. Computerized designs using solid modeling, computerized manufacturing processes using the latest in CNC equipment and computer process controlled heat treatment ensure consistent, high quality, drill bits.
3. A tailor made cutting structure provides our customer with the best combination of bit life and rate of penetration to yield the lowest cost per meter.
4. The gauge will have Carbide Gauge Inserts to prevent early erosion of the steel. In very harsh or abrasive conditions additional protection is offered by applying Hard Facing alloy material to reinforce critical wear areas of the bit.
