961 Series

Tool 961i1608B

Undercut profiles demand ball contact beyond the equator. The 961 Series delivers 300 degrees of spherical engagement where standard ball mills fall short.

This geometry extends accessible profile angles past what conventional ball nose tools can reach.
The additional contact area distributes cutting forces across more of the sphere, reducing point loading that typically limits tool life in deep undercuts.
AlTiN coating handles the heat generation from extended ball contact in steel and titanium operations.
The coating's thermal barrier properties maintain edge integrity during the prolonged engagement cycles these profiles require.
Four flutes balance surface finish with chip evacuation in the 0.158" neck diameter.
The reduced neck supports the extended ball geometry while maintaining clearance for complex part geometries.
Effective across steel, titanium, and most machinable metals where profile accessibility matters more than conventional ball nose limitations.
