961 Series

Tool 961i1606B

Standard ball nose end mills lose contact as profiles deepen past the equator. The 961i1606B maintains engagement through 300 degrees of spherical contact.

Four flutes distribute cutting forces across the extended ball geometry while the 0.158" neck diameter provides clearance in tight access situations.
The additional 60 degrees of contact beyond conventional ball mills extends profile capability into severe undercut geometries where standard tooling fails.
AlTiN coating handles the thermal load when working steel and aluminum at production feeds and speeds.
The coating's aluminum content forms a protective oxide layer that maintains edge integrity through extended cutting cycles.
This geometry works in steel, aluminum, and most machinable metals where deep spherical profiles require maximum material removal with minimal tool deflection.
