Product Overview
The CGS Tool CR143-5000.020-ALTiN is a 1/2" diameter 4-flute solid carbide corner radius end mill from the CR143 Series, sized for milling work that needs a stronger corner than a sharp square tool can offer. Its .020" radius stays small enough to keep the geometry crisp while still adding edge support.
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 wear resistance in hotter or tougher cuts. Rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's a strong fit for profiling and shoulder work.
