Tool 100i625L030A

Interrupted cuts in steel assemblies put end mills through hell. The 100i625L030A handles those entry-exit cycles by spreading impact loads across four cutting edges instead of concentrating them on two.

TiAlSiN coating runs cooler than uncoated carbide in steel and iron applications where heat buildup kills tools early.
The aluminum content in the coating creates a protective oxide layer at cutting temperatures, extending tool life in longer roughing passes where you can't flood with coolant.
The R0.03" corner radius strengthens the cutting edge at the point where chips want to tear material instead of shearing it cleanly.
In slotting operations on titanium and nickel alloys, that radius prevents the microchipping that turns a good edge into scrap after a few parts.
Four flutes keep chip load consistent as spindle speed varies.
Run-to-run performance stays predictable.
