960 Series

Tool 960i2403C

Standard ball nose end mills stop at the equator. Internal radius features with undercuts remain out of reach.

The 960i2403C cuts through 270 degrees of sphere contact.
This geometry accesses undercut profiles that conventional ball nose tools physically cannot machine.
The extended ball angle reaches into internal radii where standard tools create interference.
Four flutes balance surface finish with chip evacuation in steel and aluminum applications.
The 0.241" neck diameter provides clearance while maintaining rigidity at the 0.375" cutting diameter.
TiB₂ coating handles the thermal load when cutting above the equator.
The coating extends tool life in demanding undercut operations where conventional end mills would fail from heat buildup and premature wear.
Most machinable metals respond well to this geometry when internal features require full radius access.
