1.Cutting structure this type TCI tricone bits:
The durability of premium tungsten carbide insert is improved with new formulas and new techniques
for insert bit.
2.Gauge structure this type TCI tricone bits:
Multiple gaugeprotection with gauge trimmers on the heel of cone,
tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
3.Bearing structure of this type TCI tricone bits:
High precision bearing with two thrust faces. Ball lock the cone.
Hardfaced head bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver plated.
Abrasion resistance and seizure resistance of the bearing are improved.
4.Seal and Lubrication of this type TCI tricone bits:
Premium O-ring, optimal seal compression and curved seal structure can enhance the seal performance.
The pressure compensator system and advanced grease can greatly increase the lubricating reliability .
5.Product Application this type TCI tricone bits:
It can receive high WOB in the conventional drilling.
It is suitable for various formations by matching cutting structure with different tooth shape,
tooth density and tooth exposure height.

Our products are mainly exported to the Middle East, Europe, Russia, America and some other areas, we can ensure our drill bit are totaly new, we will provide 3 years warranty year and technical services. I know that our price is not the lowest, but we can ensure the quality, there are some malicious competition in our industry, they low the prices on purpose,Or when you recieved the goods,you find the bits are renovated,it just don't work.In fact, many of them are scalpers, they sell the used drill bit as a totally new one in the lower price.
