Tool 100i625X125A

Corner wear starts small, then accelerates. The 100i625X125A addresses this with TiAlSiN coating and a 0.125" corner radius. Two features that work together to extend tool life in interrupted cuts and harder alloys.

The coating provides thermal barrier properties that matter most when cutting titanium and nickel alloys, where heat buildup concentrates at the corner.
TiAlSiN maintains hardness at elevated temperatures better than uncoated carbide.
The 0.125" radius distributes cutting forces over a larger area, reducing the stress concentration that typically initiates corner chipping.
Four flutes keep chip load consistent across the 0.625" cutting diameter.
In steel and iron, this geometry combination handles both roughing passes and semi-finishing operations without requiring a tool change.
The radius leaves a small blend on internal corners, but eliminates the sharp corner vulnerability that cuts runs short.
