311mm 346mm Rock Reamer Foundation Pile HDD Hole Opener
Rock Reamer Foundation Pile With Best Sealed Bearing HDD Hole Opener Drill
Advantages
1. 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. Wear resistance of cutting structure is enhanced by
setting diamond inserts in the permanent contact area of the cone
where inserts are severely worn. Tungsten carbide inserts are
placed on cone top face to protect cone body from abrasive erosion.
2. Gauge Structure
With active cutting gauge protection inserts on bit body, the bit
has good gauge protection and up drill capability.
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. Product Application
It is suitable for sidetracking, deep well drilling and old well
Introduction
The reamer bits mainly consists of more than 3 cones.cutting
structure with premium tungsten carbide
hardfacing o premium tungsten carbide insert of formulas and new
techniques is utilized,and increases
wear-resistance capability of reamer.
