Product Overview
The CGS Tool 840-3125-ALTiN is a 5/16" diameter 4-flute solid carbide square end mill built for the everyday work that keeps a shop running — slotting, profiling, general milling across a mix of material types. It's part of the 840 Series, CGS Tool's dependable general-purpose line for shops that need a cutter they can reach for without overthinking it.
Balance is the theme here: a 4-flute square end geometry gives the edge strength, a 30° helix keeps cutting smooth, and ALTiN coating helps the tool shrug off heat when a cut gets demanding. Manufactured on precision CNC equipment, it's built for mild steels, stainless, cast iron, titanium, non-ferrous materials, plastics, and composites.
