Tool 190i500L006A

Small corner radius on a nine-flute end mill addresses a specific problem in finishing hardened materials. The R0.015" radius prevents micro-chipping while maintaining the sharp cutting action needed for surface quality.

TiAlSiN coating handles the heat generated when running nine flutes at the high RPMs this geometry demands.
The coating extends tool life in steel, iron, titanium, and nickel alloys without building up material on the cutting edges.
Each of the nine flutes takes a very light chip load per tooth.
The 0.5" diameter provides good rigidity for finishing operations in pockets and complex geometries.
Corner radius eliminates the stress concentration of a sharp corner while keeping edge preparation minimal.
Requires high spindle speeds and flood coolant for optimal performance.
