961 Series

Tool 961i0804B

Deep undercuts in tight spaces challenge conventional ball mills. The 961 Series addresses this with 300 degrees of ball contact geometry.

Extended spherical engagement reaches further past the equator than standard profiles.
This geometry accesses undercut features that would otherwise require specialized fixturing or multiple setups.
The 0.125" cutting diameter with 0.076" neck provides clearance in restricted areas while maintaining rigidity.
Four flutes balance surface finish with chip evacuation in steel and aluminum applications.
AlTiN coating extends tool life in higher-temperature cuts where uncoated carbide would wear prematurely.
The coating also reduces built-up edge formation in aluminum work.
The 300-degree ball contact distributes cutting forces across more of the tool geometry.
This spreads wear patterns and maintains dimensional accuracy longer in production runs.
