Tool 190i500M015A

Surface finish requirements in hardened steels demand a different approach than conventional end mills. The 190 Series addresses this with nine flutes that prioritize finish quality over material removal rate.

Each tooth carries a minimal chip load at this flute count.
That geometry produces the smooth surface finish these materials require when tolerance and appearance matter.
The 0.03" corner radius strengthens the cutting edge while maintaining the sharp profile needed for precision work.
TiAlSiN coating handles the heat generated in steel, iron, titanium, and nickel alloys during high-speed finishing passes.
The coating extends tool life when running the elevated RPMs this geometry requires.
Designed for supported setups with adequate spindle speed.
Not intended for roughing operations or deep slotting where chip evacuation becomes critical.
