961 Series

Tool 961i2408C

Deep undercuts demand more ball contact than standard geometries provide. The 961i2408C extends spherical engagement to 300 degrees.

Four flutes distribute cutting forces across the expanded ball geometry while maintaining chip evacuation in tight spaces.
The 0.241" neck diameter allows access into restricted areas where larger shanks cannot reach.
TiB₂ coating adds hardness and thermal resistance when working steel and aluminum at higher surface speeds.
The coating maintains its protective properties through the temperature cycling common in interrupted cuts.
The 300-degree ball angle reaches further past the equator than conventional ball mills.
This geometry accesses undercut profiles that would otherwise require multiple setups or specialized fixturing.
Four-flute configuration balances surface finish requirements with material removal rates across steel, aluminum, and most machinable metals.
