Product Overview
The CGS Tool 120-3281 is a 21/64" diameter 2-flute solid carbide square end mill from the 120 Series, sized for the gap between a 5/16" tool being slightly small and a 3/8" tool being more than the job needs. It handles slots, profiles, and flat-bottom features right in that in-between range.
Machined on precision CNC equipment, it holds a 30° helix matched to steady cutting in common shop applications. Uncoated and rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's a solid single-end performer.
