○ It is possible to drill hardened material (50 to 70HRC)
○ 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 and reduce vibration because of adoption of thick web and low helix.
High stiffness and reduce vibration because of adoption of thick web and low helix. So prevent sudden breakage from micro tipping
