961 Series

Tool 961i0806C

Deep undercut profiles demand more ball contact than standard geometry provides. The 961i0806C extends that contact to 300 degrees of spherical engagement.

Four flutes balance surface finish with chip evacuation in the 0.125" cutting diameter.
The 0.076" neck diameter creates clearance for complex geometry access while maintaining rigidity at this scale.
TiB₂ coating handles the thermal load when working steel and aluminum at higher surface speeds than uncoated tools allow.
The extended ball geometry reaches profile areas that 180-degree mills cannot access.
This becomes critical when machining injection mold cavities or complex aerospace components where undercut requirements exceed standard end mill capabilities.
Steel, aluminum, and most machinable metals respond well to the four-flute configuration.
