Tool 190i625M030A

Hardened steel finishing demands surface quality without chatter. The 190i625L006A delivers that through nine flutes working in light engagement.

Each tooth removes minimal material at this flute count.
That geometry produces the surface finish while the TiAlSiN coating handles the heat generated at the cutting speeds required.
The coating's aluminum content forms a protective oxide layer during machining, extending tool life in steel, iron, titanium, and nickel alloys.
The R0.006" corner radius strengthens the cutting edge without compromising finish quality.
Sharp enough for precision work, radiused enough to resist chipping under interrupted cuts.
This configuration requires high spindle speeds and rigid workholding.
Not suitable for roughing operations or deep slotting where chip evacuation becomes critical.
Best results come from consistent feeds and proper coolant delivery.
