961 Series

Tool 961i1602B

Tight neck profiles demand maximum spherical contact without sacrificing rigidity. The 961i1602B delivers 300 degrees of ball engagement while maintaining a 0.158" neck diameter for clearance in restricted geometries.

Four flutes balance surface finish with chip evacuation in steel and aluminum applications.
The extended ball contact reaches deeper undercut profiles than standard geometry allows, accessing areas where conventional ball mills lose engagement past the equator.
AlTiN coating handles the heat buildup common in steel machining operations.
The coating extends tool life when cutting through work hardening materials where uncoated carbide would wear prematurely.
The 0.25" cutting diameter provides enough rigidity for moderate depth cuts while fitting into detailed cavity work.
Effective in steel, aluminum, and most machinable metals where undercut geometry requires maximum spherical access.
