961 Series

Tool 961i2406B

Deep undercuts fail when ball contact runs out too early. The 961 Series maintains 300 degrees of spherical engagement where standard mills lose geometry.

Four flutes with AlTiN coating handle the increased chip load from extended ball contact.
The coating manages heat buildup during prolonged engagement cycles in steel and aluminum operations.
Neck diameter reduces to 0.241 inches to access tight geometries while maintaining rigidity at the cutting edge.
The 300-degree ball geometry reaches profile angles that would require multiple setups with conventional tooling.
This becomes critical in complex surfacing operations where undercut features extend well past the equator.
Tool life remains consistent because the extended ball distributes cutting forces across more surface area.
Works effectively in steel, aluminum, and most machinable metals.
Four-flute configuration balances surface finish requirements with material removal rates.
