In response to the characteristics of different cutting effects of blades in different areas on the cone, the conical blade is placed in the permanent contact area and the wedge blade is placed in the alternative contact area, thereby greatly improving the drilling efficiency. By placing the diamond blade in the permanent contact area of the cone of the severely worn blade, the wear resistance of the cutting structure can be enhanced. A tungsten carbide blade is placed on the top surface of the cone to protect the cone from abrasion.
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.
Small angled watercourse design increased the shirttail thickness and can effectively prevent the watercourse erosion.Optirnized hydraulics structure improves the clearing capability and increases ROP.
It is suitable for sidetracking, deep well drilling and old well repairing.

Single cone bit is a kind of deceleration bit, which is the speed of cone is smaller than the speed of drill, mainly disorderly cutting broken rock. It is suitable for old well sidetracking and deepening the slim hole drilling operation under high rotary speed and drilling pressure.
