Product Overview
The CGS Tool CR143-3750.015 is a 3/8" diameter 4-flute solid carbide corner radius end mill for general-purpose work where a small radius adds just enough edge strength to matter. The .015" radius takes the sharpest point off the corner without changing the way the part reads — it still looks and machines like a square-end cut.
Running on a 30° helix in a single-end build, this CR143 Series tool covers profiling, shoulder work, side walls, and any feature that calls for a radius corner instead of a knife edge. It's a solid all-around choice across mild steel, stainless, cast iron, titanium, non-ferrous stock, plastics, and composites.
