961 Series

Tool 961i2406C

Deep undercuts demand geometry that standard ball mills cannot reach. The 961i2406C extends spherical contact to 300 degrees, accessing profile areas that remain untouched by conventional designs.

Four flutes balance surface finish with chip evacuation in steel and aluminum applications.
The 0.241" neck diameter provides clearance while maintaining rigidity for consistent dimensional control across extended cutting paths.
TiB₂ coating handles the thermal cycling that comes with interrupted cuts and varying engagement angles.
The coating maintains edge integrity when cutting conditions shift between light finishing passes and heavier profiling operations.
This becomes critical when machining complex geometries where feed rates and chip loads fluctuate throughout the tool path.
The 300-degree ball geometry captures material that would otherwise require multiple setups or specialized fixturing.
Most machinable metals respond well to the extended contact geometry.
