961 Series

Tool 961i0806B

Tight undercuts demand maximum ball contact without sacrificing tool rigidity. The 961i0806B extends spherical engagement to 300 degrees.

Four flutes distribute cutting loads across the extended ball profile while the 0.076" neck diameter maintains clearance in restricted access geometries.
The additional 60 degrees of contact beyond standard ball mills opens deeper undercut profiles that would otherwise require multiple operations or specialized fixturing.
AlTiN coating handles the thermal cycling common in steel and aluminum applications where interrupted cuts generate heat spikes.
The coating maintains edge integrity during the variable engagement that characterizes complex 3D surfacing work.
This geometry works across steel, aluminum, and most machinable metals where undercut features require maximum spherical access.
The extended ball contact reduces stepover limitations in finishing operations.
