240 Series

Tool 240m040C

Large diameter aluminum cuts demand serious chip flow. At 4" cutting diameter, even moderate feed rates generate massive chip volumes that can pack the flutes and wreck surface finish. The 2-flute geometry handles this by giving each chip twice the evacuation space of a 4-flute tool.

TiB₂ coating adds thermal barrier properties that matter when you're pushing feed rates.
The coating reduces built-up edge formation on aluminum and extends tool life in copper alloys where galling becomes an issue.
The R0.1" corner radius strengthens the cutting edge without compromising the sharp geometry needed for clean plastic cuts.
At this diameter, the radius prevents chipping on entry while maintaining the edge sharpness that aluminum machining requires.
Built for shops running large aluminum components where material removal rates drive the program economics.
