961 Series

Tool 961i1612C

Standard ball nose mills lose contact as they approach deep undercuts. The 961 Series maintains engagement through 300 degrees of spherical contact.

This extended geometry reaches profile depths that would otherwise require multiple setups or compromise surface finish.
The 0.25" cutting diameter balances accessibility with rigidity for intricate work, while the 0.158" neck diameter provides necessary clearance for deep pocket geometries.
Four flutes distribute cutting loads evenly across steel, aluminum, and most machinable metals.
The TiB₂ coating adds a hard, low-friction surface that reduces built-up edge formation during interrupted cuts and extends tool life in abrasive materials.
Heat dissipation improves as chip evacuation stays consistent through the extended contact zone.
The 300-degree ball angle eliminates the undercut limitations found in conventional end mills.
