961 Series

Tool 961i1604C

Tight necks restrict access in deep pocket work. The 961i1604C addresses this with a 0.158" neck diameter supporting a 0.25" cutting diameter.

The 300-degree spherical geometry provides complete ball contact past the equator.
This extended engagement allows undercut profiles that standard ball mills cannot reach.
The narrow neck maintains rigidity while permitting tool access into confined geometries.
TiB₂ coating handles the heat generated during extended ball contact in aluminum.
The coating maintains edge integrity when the full spherical surface engages the workpiece.
Four flutes balance surface finish with chip evacuation in metals ranging from soft aluminum to gummier non-ferrous alloys.
The geometry works particularly well for die and mold applications where complex three-dimensional profiles require maximum spherical engagement.
Deep ribs and undercut features become accessible.
