961 Series

Tool 961i2408B

Deep undercuts require more ball contact than standard end mills provide. The 961 Series delivers 300 degrees of spherical engagement.

This geometry extends accessible profiles well past the equator where conventional tools lose contact.
The four-flute configuration balances surface finish with chip evacuation in steel and aluminum operations.
AlTiN coating handles the heat buildup common in extended ball contact applications while maintaining edge integrity through interrupted cuts.
The 0.241" neck diameter provides clearance for complex geometries without sacrificing rigidity at the 0.375" cutting diameter.
Most machinable metals respond well to this combination of extended ball geometry and heat-resistant coating.
The additional 60 degrees of contact over standard profiles opens up undercut geometries that otherwise require multiple setups or specialized fixturing.
