Product Overview
The CGS Tool 440-0781-ALTiN is a 5/64" diameter 4-flute solid carbide square end mill from the 440 Series, built with a double-end design for very small milling where clean square edges and compact control both matter. It's a genuinely small cutter meant for detail work.
Built on the same precision CNC equipment as CGS Tool's other general-purpose lines, it holds a 30° helix and an ALTiN coating matched to add protection when heat or wear becomes a concern in tighter features. Rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it handles small slots and fine profiles well.
