For hardened material
- It is possible to drill hardened material (50 to 70HRC)
Long Life
- By Aqua Coating (PAT.P), which is wealthy in the lubrication with the work material and excellent to heat-resistance.
So suitable for drilling hardened steel.
High stiffness
- High stiffness and reduce vibration because of adoption of thick web and low helix.
FEATURES & PERFORMANCE
High stiffness and reduce vibration because of adoption of thick web and low helix. So prevent sudden breakage from micro tipping
