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. Product Application
It is suitable for sidetracking, deep well drilling and old well
Used in
Apply to Construction, Water Drilling, Mining, Horizontal
Directional Drilling, Geothermal and Environ-mental.
