Construction 5 1/2FH Pin Tricone Drill Bit,
Construction 3 Wings Tci Drill Bit,
Construction Tricone Drill Bit 3 Wings
Customized Oil Drilling Tools Tci Rock Roller Cone Bits
Part of Tricone bits, both Steel Tooth Bits and TCI Bits are available .
With active cutting gauge protection inserts on bit body, the bit has good gauge protection and up drill capability.
High precision journal bearing. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with friction-reducing alloy. Abrasion resistance and seizure resistance of the bearing are improved. Compared with three cone bit, the leg bearing is bigger, so it can receive higher WOB and high reliability.
Bit cutters(legs) are mainly used in building big diameter piling bits or hole opener , core barrel a ccording to different formation’s .
1. It has a wide range of applications, not only for side drilling, but also for deep wells.
2. Under the same drilling pressure and formation conditions, the working torque is lower than the PDC bit. The problem of expansion and buckling of small-sized boreholes is reduced, and downhole accidents are avoided.
3. It is more suitable for large plastic formations than tri-cone bits, and it can also be applied to hard interlayers where PDC bits cannot handle other complex formations.
4. The downhole motor can be used for high-speed special drilling.

A tricone bit is a reduction bit. It is based on the fact that the speed of the cone is less than the speed of the bit. Suitable for side drilling of old well and deep hole of small well under high speed and high drilling pressure.
