Product Description

TCI tricone rock bits

1•TCI Bits Series

1).Cutting Structure

The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert 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.

5)Fast drilling rate

6)Strong cutting structure durability

7)be used for water well, oil field, underground, construction, geothermal, directional boring

8)Be used to drill low compressive strength,soft formation

9)various of model and dimension avaliable

*0)rubber seal or metal seal

*1)IADC:**7,**7,**7,**7

*2)high quality and competitive price

*3)including drill rods,drill collar,rerun steel tooth bits, ,used drill bits stock,used mud pumps,etc.

1.Various sizes from **7/8" to *6" available, from soft,
2steel tooth tricone bit (mill tooth tricone bit) and TCI tricone bit

•These types of  bits have some common features,as follows 

1.Force balanced,resist impact to the blade during high-speed drilling,to make bit work stable.

2.Plus wear knot section,reduce collion in the hugh-speed rotational vibration.

3.Patented matrix formulation,extended bit life.

4.Optimal hydraulic desigh,easy to move out the drill cuttings and cooling.

5.Equipped with back reaming teeth.

6.The cutter is high performance to increase the ability of anti-impact and anti-abrasive.
