961 Series

Tool 961i2418B

Deep undercuts require ball contact beyond the standard 180-degree equator. The 961 Series extends that contact to 300 degrees.

This geometry reaches profile angles that standard ball mills cannot access.
The extended spherical engagement maintains cutting forces across a broader contact zone, reducing point loading that typically occurs when conventional ball mills attempt steep undercuts.
Four flutes balance surface finish with chip evacuation in the 0.375-inch cutting diameter.
The 0.241-inch neck diameter provides clearance while maintaining rigidity for the extended ball geometry.
AlTiN coating handles the thermal buildup common in deep pocket operations.
The aluminum titanium nitride layer maintains hardness at elevated temperatures while providing lubricity during the extended tool engagement periods typical of undercut profiling.
Works in steel, aluminum, and most machinable metals where complex geometry requires maximum spherical access.
