961 Series

Tool 961i1202B

Tight radius undercuts require ball contact beyond the equator. The 961i1202B extends spherical engagement to 300 degrees.

Four flutes distribute cutting forces across the extended ball geometry while maintaining the narrow 0.117" neck diameter needed for deep pocket access.
The AlTiN coating handles the thermal load from interrupted cuts in steel and aluminum applications where standard TiN breaks down.
This coating chemistry maintains hardness at elevated temperatures while providing lubricity during entry and exit cycles.
The 300-degree ball angle accesses profile geometries that conventional ball mills cannot reach.
The 0.1875" cutting diameter balances material removal rates with the precision required for complex surface generation.
Steel, aluminum, and most machinable metals machine predictably with this geometry.
