Tool 100i375X030A

Most shops run into the same problem with 3/8" end mills in steel. They start sharp, cut clean for a while, then edge wear accelerates and suddenly you're watching for chatter on every pass.

The 100i375X030A addresses this with four flutes that distribute cutting forces evenly across the tool diameter.
In steel, iron, titanium, and nickel alloys, that force distribution translates to more predictable wear patterns.
The TiAlSiN coating adds a thermal barrier that keeps cutting temperatures stable during extended runs.
Particularly important when you're pushing feed rates in harder alloys.
The R0.03" corner radius removes the stress concentration you get with sharp corners.
Edge strength improves, and you get fewer random failures mid-cut.
Four flutes mean you can maintain surface finish while increasing table feed, especially in side milling operations where chip evacuation isn't the limiting factor.
