Product Overview
The CGS Tool CR143-3750.020 is a 3/8" diameter 4-flute solid carbide corner radius end mill from the CR143 Series, designed for general-purpose milling where edge strength matters. Its .020" radius adds support to the cutting corner while keeping the part detail sharp.
Built on the same precision CNC equipment as CGS Tool's other general-purpose lines, it holds a 30° helix matched to a dependable, clean-cutting feel. Uncoated and rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's suited to profiling, shoulder work, and radius-corner applications.
