961 Series

Tool 961i1608C

Tight radius undercuts demand more ball contact than standard mills can deliver. The 961 Series extends spherical engagement to 300 degrees.

This geometry reaches deeper into undercut profiles where conventional ball mills lose contact past the equator.
The extended ball profile maintains cutting action through complex 3D surfaces without repositioning the workpiece.
Four flutes balance surface finish with chip evacuation in the 0.25" cutting diameter.
TiB₂ coating handles the thermal load from extended ball contact in aluminum operations.
The coating's hardness supports the aggressive geometry when machining most machinable metals.
Neck diameter steps down to 0.158" for clearance in restricted access applications.
The 300-degree ball angle provides continuous cutting engagement through undercut transitions that would require multiple setups with standard tooling.
