961 Series

Tool 961i0801C

Small diameter operations in complex geometries demand precise undercut access without sacrificing tool life. The 961i0801C extends spherical contact to 300 degrees, reaching profile geometries that standard ball nose end mills cannot access.

Four flutes balance surface finish requirements with chip evacuation in the 0.125-inch cutting diameter.
The 0.076-inch neck diameter provides clearance for deep pocket work while maintaining rigidity for steel and aluminum operations.
TiB₂ coating addresses the thermal buildup common in small diameter tooling, extending cutting edge life through improved heat dissipation and reduced friction coefficients.
This geometry works effectively across most machinable metals where undercut profiles exceed the capabilities of conventional ball nose end mills.
The additional spherical engagement distributes cutting forces more evenly than partial-contact tooling.
