Product Overview
The CGS Tool 140-4375-ALTiN is a 7/16” diameter 4-flute solid carbide square end mill from the 140 Series, sized for shops that need more flute contact than a 2-flute tool offers without stepping up to a larger diameter. It's a straightforward, no-surprises square end mill built for everyday production work.
Manufactured on the same precision CNC equipment as the rest of CGS Tool's General Purpose range, it holds the standard 30° helix and benefits from an ALTiN coating that extends service life under repeated use. It's rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, making it one of those tools that earns its keep simply by working reliably, job after job.
