961 Series

Tool 961i1612B

Deep undercuts demand more ball contact than standard profiles allow. The 961i delivers 300 degrees of spherical engagement where conventional end mills reach their geometric limits.

The extended ball geometry accesses profile angles well past the equator, maintaining consistent surface finish through complex three-dimensional forms.
Four flutes balance chip evacuation with surface quality in steel and aluminum applications.
The 0.158" neck diameter provides clearance for restricted access while maintaining rigidity during contouring operations.
AlTiN coating extends tool life in higher-speed steel cutting where heat generation typically limits performance.
The aluminum titanium nitride barrier maintains edge sharpness longer than uncoated carbide in interrupted cuts and varying feed rates common to complex profiling work.
Designed for production environments requiring reliable undercut capability in most machinable metals.
