Product Overview
The CGS Tool 820-3125-ALTiN is a 5/16" diameter 2-flute solid carbide square end mill built specifically for long-reach general-purpose milling, where the slot or profile runs deeper than a standard-length tool can follow. It belongs to the 820 Series, CGS Tool's extended-reach general-purpose line.
What sets this tool apart is the 1-3/4" length of cut, giving real depth relative to the 5/16" diameter, and the ALTiN coating that helps the edge handle the extra heat that comes with longer reach. Running a 30° helix, it holds up through mild steel, stainless, cast iron, titanium, non-ferrous material, plastics, and composites.
