Tool 100i125LFA

Small diameter end mills break. That's the reality when you're cutting keyways or narrow slots in hardened steel. The 100i125LFA addresses this with TiAlSiN coating that extends tool life where heat buildup normally kills carbide.

Four flutes keep cutting forces balanced even at 0.125" diameter.
In steel and titanium, that balance prevents the deflection that leads to premature failure.
The R0.004" corner radius reinforces the cutting edge without compromising corner definition.
Enough to resist chipping on interrupted cuts, small enough to maintain crisp internal corners.
TiAlSiN coating handles the thermal cycling that comes with small-diameter machining.
Heat builds faster in confined chip evacuation zones, and this coating maintains hardness at temperatures where uncoated carbide starts to soften.
