5/32" 4-Flute Uncoated Single-End Square End Mill

This 5/32" diameter Skookum carbide end mill features four-flute geometry, a square cutting end and an uncoated finish for stable, precise material removal. Its 5/16" length of cut and compact 2" overall length provide a rigid setup for profiling, shallow slotting and machining flat-bottom features.

Stable Cutting and Clean Surface Finishes

The four-flute design provides multiple cutting edges for stable material removal, productive feed rates and smooth finishes where chip clearance permits. Its uncoated finish maintains sharp cutting edges for aluminum and other non-ferrous materials, while the square end geometry produces flat-bottom cuts, defined shoulders and precise profiles.
