961 Series

Tool 961i3212C

Standard ball nose mills lose cutting ability past the equator. The 961i3212C extends usable geometry to 300 degrees of spherical contact.

Four flutes balance surface finish with chip evacuation in aluminum operations.
The 0.323" neck diameter maintains rigidity while accessing restricted geometries that larger neck mills cannot reach.
TiB₂ coating handles the thermal cycling common in interrupted cuts and varying engagement angles.
The coating's hardness reduces built-up edge formation when machining aluminum alloys.
This geometry suits complex 3D profiling where maximum undercut capability determines part feasibility.
The extended ball contact eliminates the need for additional setups or specialized fixturing in many applications.
Works effectively in aluminum and most other non-ferrous metals where spherical interpolation creates the primary surface.
