Product Overview
The CGS Tool 140-1406-ALTiN is a 9/64" diameter 4-flute solid carbide square end mill from the 140 Series, designed for smaller milling applications where a sharp square-end finish is needed. It's a good choice for clean slotting and light side wall milling.
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 better heat and wear handling than an uncoated option. Rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it gives machinists a stable small-diameter tool.
