Product Overview
Aluminum work that needs both speed and a solid finish quality is where the 5321-S does pretty well , show up as 3/8" diameter. It’s this 3-flute square end mill from the Ferocious 3x 5300 Series, made to take off the metal fast without leaving a harsh surface behind.
ZrN coating, wiper end geometry, variable helix, and variable pitch all work together to reduce chatter and harmonics during aggressive cutting. That combination lets shops push feed rates further while still walking away with a clean finish across aluminum, copper, brass, plastics, and composites.
