Tool 100i625X030A

Steel work generates heat. The question is whether the end mill holds long enough to matter.

The 100i625X030A carries TiAlSiN coating specifically for extended runs in steel, iron, titanium, and nickel alloys.
Four flutes keep chip load distribution even when you're pushing feed rates in side milling operations.
That consistency translates to predictable tool life.
The edge wears at the same rate across all cutting surfaces instead of failing at one weak point.
The R0.03" corner radius strengthens the cutting edge where stress concentrates.
In profiling and contouring work, that small radius prevents chipping while maintaining tight corner definition.
The coating adds oxidation resistance at temperatures where uncoated carbide starts breaking down.
0.625" cutting diameter handles most general machining tasks without the deflection issues of smaller tools.
