Tool 190i625M006A

Surface finish requirements in hardened alloys don't leave room for compromise. The 190i500L030A delivers consistent results when you need mirror-like finishes on steel, iron, titanium, and nickel alloys.

Nine flutes distribute the cutting load across more edges, allowing each tooth to take a minimal chip.
This geometry requires high spindle speeds and rigid setups but produces the surface quality that secondary operations can't match.
The TiAlSiN coating handles the heat buildup that comes with these speeds while extending tool life in demanding alloy applications.
The R0.03" corner radius strengthens the cutting edge without compromising the finish.
Sharp enough for precision work, radiused enough to resist chipping under the light but frequent engagement that nine-flute geometry demands.
Built for finishing passes where surface quality drives the operation.
