961 Series

Tool 961i2404C

Tight undercuts demand more ball contact than standard geometry allows. The 961i2404C extends spherical engagement to 300 degrees.

This geometry accesses profile features that conventional ball mills cannot reach.
The extended ball contact runs deeper into undercut surfaces, maintaining consistent surface finish where radius transitions into vertical walls.
Four flutes balance material removal with chip evacuation in the restricted envelope.
TiB₂ coating handles the elevated temperatures these deep cuts generate.
The titanium diboride layer maintains hardness at temperature while reducing built-up edge formation on steel surfaces.
The 0.241" neck diameter provides clearance for the extended ball geometry without compromising rigidity on the 0.375" cutting diameter.
Works in steel, aluminum, and most machinable metals.
Particularly effective where conventional ball mills lose contact in complex curved surfaces.
