Tool 190i375M004A

Surface finish requirements in hardened steels don't leave room for compromise. The 190i375M030A delivers that finish through nine flutes working at light chip loads, each tooth removing minimal material to avoid work hardening and surface degradation.

The TiAlSiN coating handles the heat generated at the high spindle speeds this geometry demands.
Without proper coating, tool life drops rapidly when running the RPMs needed to make nine flutes effective.
The 0.03" corner radius strengthens the cutting edge while maintaining the sharp corner geometry required for detailed finishing work.
Designed for steel, iron, titanium, and nickel alloys where surface quality drives the operation.
Requires rigid setup and high RPM capability.
The light engagement per tooth means this geometry works best on well-supported workpieces with minimal deflection.
