Tool 100i250X030A

Quarter-inch end mills take a beating in production runs. The 100i250X030A handles that reality with four flutes that spread cutting forces evenly, reducing the load spikes that cause premature wear in steel and titanium work.

The TiAlSiN coating runs cooler than uncoated carbide, extending tool life when heat buildup becomes the limiting factor.
In interrupted cuts on iron castings or continuous passes through steel bar stock, that thermal management keeps the cutting edge stable longer.
The R0.03" corner radius reinforces the edge geometry where maximum stress concentrates, preventing the micro-chipping that starts tool failure.
Four-flute geometry maintains consistent chip evacuation while maximizing metal removal rates.
Surface finish stays predictable from first cut to last because each flute carries the same load through the rotation.
