HDD 16 Inch Rock Reamer Hole Opener For Directional Drilling
Hot Sale Credit Quality HDD 16 inch rock reamer hole opener for directional drilling
1. Cutting Structure
The reaming bit is mainly composed of more than 3 cones. The cutting structure of advanced tungsten carbide surfacing and the advanced tungsten carbide blade of new technology improve the wear resistance of the reamer.
2. Bearing Structure
High-precision journal bearings. The ball locks the cone. Hard bearing surface. Tapered bearings inlaid with friction reducing alloy. Improve the wear resistance and seizure of the bearing. Compared with tri-cone bits, tri-cone bits have larger leg bearings, which can withstand higher weight-on-bit and higher reliability.
3. Hydraulic Design
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.
4. Gauge Structure
With active cutting gauge protection inserts on bit body, the bit has good gauge protection and up drill capability.
5. Product Application
It is suitable for sidetracking, deep well drilling and old well
