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 three cones.
Advanced cutting structure of tungsten carbide surfacing layer and
advanced tungsten carbide blade with new technology improve the
wear resistance of reamer.
2. Bearing Structure
High precision journal bearing. The ball locks the cone. Hard
bearing surface. The tapered bearing is inlaid with antifriction
alloy. Improve the bearing wear resistance and bite. Compared with
tri cone bit, the outrigger bearing of tri cone bit is larger,
which can bear higher WOB and higher reliability.
3. Hydraulic Design
The small angle channel design increases the tail thickness of the
shirt, which can effectively prevent water channel 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
