961 Series

Tool 961i1614B

Deep undercuts demand more than standard ball geometry allows. The 961 Series extends spherical contact to 300 degrees.

This configuration reaches profile angles that conventional mills cannot access.
The extended ball contact maintains consistent chip evacuation while supporting complex three-dimensional geometries.
Four flutes balance surface finish requirements with chip clearing capacity in the 0.25" cutting diameter.
The 0.158" neck diameter provides tool rigidity while allowing access into tight radius transitions.
AlTiN coating handles the temperature cycling common in steel operations and extends tool life in aluminum applications where built-up edge formation typically shortens tool life.
This geometry suits contour milling operations in steel, aluminum, and most machinable metals where undercut features require spherical tool paths beyond 270 degrees of engagement.
