961 Series

Tool 961i1610C

Tight undercut profiles demand maximum ball contact without sacrificing tool life in production steel work. The 961i features 300-degree spherical geometry that extends accessible profile paths well past the equator.

TiB₂ coating handles the thermal load in steel applications where uncoated tools wear rapidly.
The coating's low friction properties reduce heat buildup during extended ball contact, maintaining edge integrity through longer cycle times.
Four flutes balance surface finish requirements with chip evacuation in the constrained geometry.
The 0.158" neck diameter provides clearance for deep undercut operations while maintaining adequate rigidity at 0.25" cutting diameter.
Material removal rates stay consistent across steel, aluminum, and most machinable metals.
Ball contact extends to 300 degrees for maximum undercut accessibility.
