961 Series

Tool 961i3232B

Deep undercuts demand more ball contact than standard geometry provides. The 961i3232B extends spherical engagement to 300 degrees, accessing profile geometries that conventional ball mills cannot reach.

The extended ball geometry creates maximum contact with curved surfaces while maintaining structural integrity through the 0.323" neck diameter.
Four flutes balance material removal rates with chip evacuation in the confined spaces typical of undercut operations.
AlTiN coating handles the thermal demands of steel machining while extending tool life in aluminum applications.
The coating's aluminum oxide layer forms during cutting, creating a barrier against heat buildup that occurs during extended ball contact operations.
This geometry works across steel, aluminum, and most machinable metals where deep spherical profiles are required.
The 300-degree contact zone provides consistent surface finish through the entire undercut profile.
