Tool 100i313S015A

Tight-tolerance work in hardened steel puts maximum stress on cutting edges. The 100i313S015A handles those conditions by combining even chip distribution with edge protection where it matters most.

Four flutes keep chip load consistent across the 0.3125" cutting diameter.
That consistency becomes critical in steel and titanium work, where uneven loading leads to premature edge breakdown and dimensional drift.
The R0.015" corner radius strengthens the cutting edge at the point of maximum stress while maintaining clean corner definition in profiling operations.
TiAlSiN coating adds thermal stability during extended cuts in nickel alloys and hardened materials.
The coating handles the heat buildup that comes with smaller diameter tooling, letting you maintain feeds without backing down on depth of cut.
In production runs on steel components, that thermal protection translates to predictable tool life from first part to last.
