961 Series

Tool 961i3212B

Standard ball nose end mills limit undercut access. The 961 Series extends spherical engagement to 300 degrees.

The extended ball geometry reaches deeper undercut profiles than conventional mills.
Where standard tools lose contact past the equator, the 961 maintains cutting engagement through three-quarters of the sphere.
This geometry accesses complex mold cavities and sculptured surfaces that would otherwise require multiple setups or specialized tooling.
Four flutes balance surface finish with chip evacuation in steel and titanium applications.
The 0.323" neck diameter provides clearance while maintaining rigidity at the 0.5" cutting diameter.
AlTiN coating extends tool life in higher-temperature cutting conditions common with steel machining operations.
The 300-degree ball contact eliminates secondary operations on complex three-dimensional profiles.
Feed rates remain consistent through the extended engagement zone.
