961 Series

Tool 961i3224C

Tight necks limit access on complex undercuts. The 961i3224C reaches where standard ball mills cannot.

300-degree ball contact extends usable geometry well past the equator, accessing deeper undercut profiles than conventional designs allow.
The 0.323" neck diameter maintains rigidity while maximizing clearance in restricted areas.
Four flutes balance surface finish with chip evacuation across steel, aluminum, and most machinable metals.
TiB₂ coating addresses the thermal challenges of extended ball contact.
The coating's low friction coefficient reduces heat buildup during the prolonged material engagement that 300-degree geometry creates.
This thermal management becomes critical when the extended contact zone generates more heat per revolution than standard ball nose operations.
The half-inch cutting diameter provides substantial material removal capacity while the geometry maintains access to complex three-dimensional profiles.
