Tool 100i125FA

Small diameter end mills break. The thinner the tool, the more critical edge stability becomes when you're working in steel and titanium alloys where heat buildup happens fast.

The 100i125FA runs a TiAlSiN coating that handles the thermal cycling better than uncoated carbide in these harder materials.
At 0.125" cutting diameter, that heat management matters because there's less mass to absorb temperature spikes during interrupted cuts and slotting operations.
Four flutes keep chip load consistent even when cutting forces try to deflect the tool.
The R0.004" corner radius strengthens the cutting edge without compromising corner definition on your parts.
In profiling and finishing passes on steel components, that radius prevents the microchipping that kills small end mills early.
Four flutes also mean shorter chips in the limited flute space, so evacuation stays clean in deeper cuts.
