Product Overview
The CGS Tool 220-4375 is a 7/16” diameter 2-flute solid carbide square end mill from the 220 Series, sized for shops that need a slightly lighter cut than a 4-flute tool but still want square-end precision. With a shorter 5/8” length of cut, it's built to stay rigid rather than reach deep, which keeps chatter down on shallower work.
Like the rest of CGS Tool's General Purpose line, it's manufactured on precision CNC equipment with a 30° helix and holds up across a genuinely wide material range. It ships uncoated, which keeps cost down for shops running it on mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites where a coating isn't strictly necessary.
