Tool 190i500M006A

Finishing half-inch features in hardened materials without chatter requires careful balance between surface speed and chip load. The 190i500M015A addresses this with nine flutes that distribute cutting forces across more contact points.

TiAlSiN coating extends tool life in steel, iron, titanium, and nickel alloys by reducing thermal buildup during the high-speed operations this geometry demands.
The coating's aluminum content forms a protective oxide layer at elevated temperatures.
The R0.015" corner radius strengthens the cutting edge while maintaining the sharp geometry needed for fine finishes.
This radius prevents microchipping that would telegraph into the surface finish.
Each of the nine teeth removes minimal material per revolution, which is what generates the surface quality.
Requires high spindle speeds and a setup with minimal runout.
Not intended for roughing operations or deep slotting where chip evacuation becomes critical.
