More details ofTungsten carbide insert tooth bit
1. Cutting Structure of this series tricone rockbit:
The durability of premium tungsten carbide inserts is improvedwith new formulas and new techniques for insert bit. The wear-resistance ofteeth is enhanced with premium tungsten carbide hard facing on the toothsurfaces for steel tooth bit.
2. Gauge Structure of this series tricone rockbit:
Multiple gauge protection with gauge trimmers on heel and gaugeinserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearinglife.
3. Bearing Structure of this series tricone rockbit:
High precision bearing with two thrust faces. Balls lock thecone. Hard face heard bearing surface. Cone bearing inlaid withfriction-reducing alloy and then silver-plated. Abrasion resistance and seizureresistance of the bearing are improved and suitable for high rotary speed.
4. Seal and Lubrication of this series tricone rockbit:
The advanced metal seal package consists of two metal seats andtwo elastic energizers. Compressed energizers ensure good contact being kept ontwo sealing surfaces of metal rings by elastic force, and achieve the bearingseal. In the drilling, metal seal are relatively dynamic, and the energizers arestatic. This will improve the reliability and durability of bearing seal. Thepressure compensator system and advanced grease can greatly increase thelubricating reliability.
5. Product Application of this series tricone rockbit:
It is suitable for down hole motor and high speedapplications.
We have been in this line over 30 years with rich experience. Our company takes years with the used and new PDC(diamond) bits, tricone bits, TCI bits, steel tooth bits, single cone bits covering all IADC code. We can provide brand Kingdream, Lilin, CS, Smith, Hughes and other brand bits as you want.
It's our pleasure to do business with you, the friend from all over the world.
