961 Series

Tool 961i1602C

Tight neck geometries limit access in complex undercut work. The 961i1602C extends ball contact to 300 degrees for deeper spherical engagement than standard profiles.

The 0.158" neck diameter provides clearance while maintaining rigidity at the 0.25" cutting diameter.
Four flutes balance surface finish with chip evacuation in steel and aluminum applications.
TiB₂ coating handles the thermal cycling that comes with interrupted cuts and varying engagement angles common in undercut operations.
The extended ball geometry reaches profile areas that conventional end mills cannot access.
This becomes critical when machining complex cavities or mold surfaces where maximum material removal depends on maintaining contact past the equator.
Works in steel, aluminum, and most machinable metals where undercut geometry requirements exceed standard ball nose capabilities.
