961 Series

Tool 961i3216C

Deep undercuts demand more ball contact than standard profiles allow. The 961i3216C extends spherical engagement to 300 degrees.

Four flutes distribute cutting forces across the extended ball geometry while maintaining chip evacuation in tight spaces.
The 0.323" neck diameter provides clearance for complex contours without sacrificing rigidity at the 0.5" cutting diameter.
TiB₂ coating handles the thermal cycling that comes with interrupted cuts in aluminum.
The coating's low friction coefficient reduces built-up edge formation during extended roughing operations.
Heat dissipation improves when the cutting load spreads across more of the ball surface.
The geometry reaches profile angles that would require multiple setups with conventional end mills.
Works effectively in aluminum and most other non-ferrous metals where undercut access determines cycle time.
