Tool 110i250A

Quarter-inch tooling in heat-sensitive alloys demands thermal discipline. Smaller diameters concentrate heat faster, and stainless or titanium will punish any tool that can't shed it efficiently.

The 110i250A is a 3-flute solid carbide end mill with TiAlSiN coating for steel, iron, titanium, and nickel alloys.
Three flutes provide the chip clearance needed to keep cutting temperatures manageable in materials that work-harden under thermal stress.
The TiAlSiN coating adds wear resistance without building heat the way thicker coatings can.
At 0.25" diameter with R0.006" corner radius, the slight radius strengthens the cutting edge against chipping while maintaining crisp corner definition in profiling cuts.
In quarter-inch slotting operations on stainless or titanium, controlled heat means controlled surface finish.
