240 Series

Tool 240m030C

Large diameter aluminum work puts thermal stress where you least want it. The bigger the tool, the more heat builds at the cutting edge, especially when surface footage climbs with diameter. TiB₂ coating handles that thermal load better than uncoated carbide while maintaining the sharp edge geometry aluminum demands.

This 3-inch diameter end mill uses the same open 2-flute design that works at smaller sizes, just scaled for heavy stock removal in aerospace and automotive applications.
The R0.1" corner radius strengthens the cutting edge against chipping while maintaining clean part finishes in soft materials.
The 2.9" neck diameter keeps rigidity high near the cutting zone.
Built for shops running large aluminum components where maintaining surface speed means high spindle RPM and aggressive feed rates.
