960 Series

Tool 960i1606C

Standard ball nose end mills stop at 180 degrees of contact. Internal undercuts require more.

The 960i1606C extends ball geometry to 270 degrees, accessing profiles that conventional tools cannot reach.
Four flutes distribute cutting forces across the extended contact zone while maintaining surface finish in steel and aluminum applications.
TiB₂ coating adds thermal barrier protection during the extended dwell time these undercut operations typically require.
The 0.158" neck diameter provides clearance in confined geometries while the 0.25" cutting diameter handles finish passes in internal radii.
This geometry combination addresses the access problem in injection mold cores and complex cavity work where standard ball nose mills leave material behind.
Material removal occurs above the equatorial line where undercut profiles exist.
The extended ball contact maintains consistent chip evacuation through the full 270-degree engagement.
