961 Series

Tool 961i1212C

Tight radius undercuts demand ball contact beyond the standard 180-degree envelope. The 961 Series delivers 300 degrees of spherical engagement.

Extended ball geometry reaches profile angles that conventional end mills cannot access.
The additional 120 degrees of contact area allows deeper undercut machining while maintaining surface finish control across the extended envelope.
TiB₂ coating adds wear resistance for steel applications where extended tool life matters more than raw cutting speed.
The coating performs particularly well in interrupted cuts and varying engagement conditions common in undercut profiling operations.
Four flutes balance chip evacuation with surface finish in steel, aluminum, and most machinable metals.
The 0.158" neck diameter provides clearance for deep pocket access while supporting the 0.25" cutting diameter against deflection forces.
