961 Series

Tool 961i2418C

Complex undercut geometries demand more than standard ball contact. The 961i reaches 300 degrees of spherical engagement.

This extended contact zone accesses profile geometries well beyond what conventional ball mills can machine.
The 0.375" cutting diameter pairs with a 0.241" neck to maintain strength while maximizing clearance in tight spaces.
Four flutes balance surface finish with chip evacuation across steel, aluminum, and most machinable metals.
TiB₂ coating addresses the thermal challenges of extended ball contact.
The coating's thermal barrier properties manage heat buildup during the prolonged tool-workpiece engagement that 300-degree geometry creates.
This becomes critical when maintaining surface integrity on complex three-dimensional profiles where conventional cooling access is limited.
The geometry enables complete undercut profiling in applications where multiple setups would otherwise be required.
