Product Overview
The CGS Tool 840-6250-ALTiN is a 5/8" diameter 4-flute solid carbide square end mill from the 840 Series, sized for general-purpose jobs that need extra reach for deeper walls and taller profiles. Its long 3" length of cut is what sets it apart from a standard-depth tool.
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 help the tool hold up as heat builds in the cut. Rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's a practical long-reach option.
