100 Series

Tool 100i156FA

Small diameter work demands precision. The 100i156FA delivers it at 0.1563" cutting diameter through geometry that balances cutting forces across four flutes instead of concentrating them on two.

TiAlSiN coating handles the heat buildup that comes with smaller end mills running at higher surface speeds.
The aluminum content in the coating acts as a thermal barrier, keeping the cutting edge below temperatures where carbide starts to soften.
In steel and iron, that thermal protection translates to longer tool life when spindle speeds climb to maintain proper chip loads at small diameters.
The R0.004" corner radius strengthens the cutting edge without sacrificing the sharp corner geometry needed for detailed features.
Four flutes maintain chip evacuation while providing the surface finish quality that small diameter finishing work requires.
