100 Series

Tool 100m040FA

Large diameter cuts in hardened steels test every aspect of your setup. The 100m040FA handles these demanding operations by spreading cutting forces across four flutes, preventing any single edge from carrying excessive load. At 4" cutting diameter, that force distribution becomes critical for maintaining dimensional accuracy through long production runs.

The TiAlSiN coating adds a thermal barrier that becomes essential when cutting at this scale.
Higher cutting speeds generate more heat, and the coating keeps that heat from reaching the carbide substrate where it would accelerate wear.
The R0.1" corner radius strengthens each cutting edge against the higher impact forces that come with heavy cuts in steel, iron, titanium, and nickel alloys.
Four flutes maintain consistent chip evacuation even in deep slotting operations where chip management becomes challenging.
Solid carbide.
