960 Series

Tool 960i2412B

Standard ball nose end mills stop at the equator. The 960i2412B reaches 270 degrees around the sphere.

This extended geometry accesses undercut profiles and internal radii that conventional tools cannot physically reach.
The AlTiN coating handles the increased cutting forces that come with extended ball contact, particularly when working hardened steels where heat buildup becomes problematic.
Four flutes balance surface finish with chip evacuation in steel and aluminum applications.
The 0.241" neck diameter provides clearance for deep cavity work while maintaining rigidity at the cutting end.
The 270-degree ball angle means you can machine true undercuts without complex fixturing or multiple setups.
Especially useful for injection mold cores and complex aerospace geometries where undercut features are functional requirements rather than design preferences.
