Tool 100i125M015A

Small end mills break. Usually right when you need them most. The 100i125M015A builds edge strength into a 1/8" diameter tool through deliberate geometry choices that prioritize reliability over aggressive cutting parameters.

Four flutes keep chip load manageable even at higher feed rates.
With less material per tooth to remove, each cutting edge sees reduced stress.
Particularly important when working in the tighter clearances that small tooling often requires.
The R0.015" corner radius eliminates the sharp corner that typically initiates tool failure, spreading cutting forces across a stronger edge geometry.
TiAlSiN coating adds wear resistance without building up thickness that would compromise the small tool's already limited chip evacuation.
In steel and iron applications, that combination of edge strength and wear protection extends tool life where breakage typically dominates the failure mode.
