Product Overview
The CGS Tool M140-040-ALTiN is a 4mm diameter 4-flute solid carbide square end mill from the metric 140 Series, sized for small metric milling where clean slotting, profiling, and side wall work all need reliable control. It's a practical metric cutter for standard jobs.
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 give added protection against heat and wear. Rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it performs a smooth general-purpose cutting action.
