Tool 190i625L030A

Nine flutes means each tooth barely kisses the work. The 190 Series handles finishing cuts in steel, iron, titanium, and nickel alloys where surface finish cannot be compromised.

TiAlSiN coating runs cooler than standard TiAlN when cutting these materials.
The aluminum content forms a protective oxide layer at higher cutting temperatures.
That thermal barrier keeps the edge sharp longer in demanding alloys.
The R0.03" corner radius eliminates the stress concentration of a sharp corner while maintaining crisp wall definition.
Radius strengthens the cutting edge without sacrificing geometric accuracy in your finished part.
This geometry requires high spindle speeds and a setup with minimal overhang.
Machine rigidity determines success more than feed rate.
Light axial depths, high surface speeds.
