Tricone palm cone cutter hard rock

SD Single Cone Bit Series:

Cutting Structure

In response to the characteristics that inserts in different areas on the cone have different cutting actions, conical inserts are placed in permanent contact area and wedge inserts are placed in alternative contact area so that the drilling efficiency is greatly improved.

Gauge Structure

With active cutting gauge protection inserts on bit body, the bit has good gauge protection and updrill capability.

Bearing Structure

High precision journal bearing with two thrust faces. Balls lock the cone. Hardfaced head 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.

Hydraulic Design

Small angled watercourse design increased the shirttail thickness and can effectively prevent the watercourse erosion. Optimized hydraulics structure improves the cleaning capability and increases ROP.

Product Application

It is suitable for sidetracking, deep well drilling and old well repairing.
