Product Overview
The CGS Tool 720-3125-ALTiN is a 5/16” diameter 2-flute solid carbide square end mill from the 720 Series, built for shops working smaller-diameter jobs that still need square-end accuracy under load. At this size, tool rigidity matters more than raw stock removal, and the 720 Series is built around that priority.
It carries the same 30° helix and precision CNC grinding found across CGS Tool's General Purpose lineup, and the ALTiN coating gives it a real edge in heat resistance compared to running it bare, useful given how quickly smaller-diameter tools heat up under sustained cutting. It's rated for mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, so it isn't limited to a single application.
