961 Series

Tool 961i2424C

Deep undercut profiles require ball contact beyond the equator. The 961i2424C extends spherical engagement to 300 degrees.

Four flutes distribute cutting forces across the extended ball geometry, maintaining surface finish consistency in steel and aluminum applications.
The 0.241" neck diameter provides clearance for complex contours while supporting the 0.375" cutting diameter through demanding profiles.
TiB₂ coating addresses the thermal challenges of extended ball contact in metallic workpieces.
The coating's thermal barrier properties become critical when more of the cutting edge engages simultaneously, particularly in steel where heat buildup compromises tool life during prolonged spherical cuts.
The geometry accesses profile angles that standard ball mills cannot reach.
Maximum undercut capability without repositioning the workpiece.
