Product Overview
The CGS Tool CR143-2500.030 is a 1/4" diameter 4-flute solid carbide corner radius end mill from the CR143 Series, sized for milling work where a little added edge strength makes a real difference. Its .030" radius protects the cutting corner while keeping the part geometry crisp.
Built on the same precision CNC equipment as CGS Tool's other general-purpose lines, it holds a 30° helix matched to its diameter for dependable general-purpose cutting. Uncoated and rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it suits profiling, shoulder work, and radius-corner applications well.
