100 Series

Tool 100m040A

Four-inch cuts in steel put serious stress on carbide edges. The 100m040A handles that stress by spreading it out. Four flutes means each cutting edge does less work per revolution, which translates to more consistent temperatures and longer tool life.

The TiAlSiN coating adds thermal stability when you're running production speeds in steel and titanium.
That extra heat resistance keeps the edge geometry intact through extended cuts, particularly in side milling where engagement varies.
The R0.1" corner radius prevents the sharp corner failures that can end a cut early.
Just enough radius to strengthen the edge without affecting part geometry in most applications.
In heavy roughing operations on steel or titanium, that combination of even chip distribution and thermal coating performance means fewer tool changes per shift.
Solid carbide.
