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.
Through the special structure of the cone, equal wear on the permanent contact area and alternating contact area of the drill bit is achieved.
The optimized hydraulic structure improves the cleaning ability of the hydraulic system to the cone and bottom of the well, and ensures a high mechanical drilling speed.
By setting an active cutting cone ball gauge pressure block on the head body, the drill bit has good protection performance and improves its hole expanding ability.

Tri-cone bit is a decelerating bit. It is based on the fact that the speed of the cone is less than the speed of the bit. It is suitable for sidetracking of old wells and deepening of small boreholes under high speed and high drilling pressure.
