961 Series

Tool 961i1203C

Tight radii and deep undercuts demand more ball contact than standard geometry provides. The 961i1203C delivers 300 degrees of spherical engagement where conventional end mills fall short.

Four flutes balance surface finish with chip evacuation in the 0.1875" cutting diameter.
The 0.117" neck diameter maintains rigidity while accessing restricted geometries that larger necks cannot reach.
TiB₂ coating handles the heat buildup common in deep spherical cuts, extending tool life when working steel and aluminum at higher surface speeds.
The extended ball contact pushes accessible undercut profiles well past the equator.
This geometry reaches areas that typical profiling tools simply cannot access, particularly in complex 3D surfaces and tight internal features.
Works effectively across steel, aluminum, and most machinable metals where undercut capability determines part feasibility.
