Product Overview
The CGS Tool CR143-3750.125 is a 3/8" diameter 4-flute solid carbide corner radius end mill from the CR143 Series, sized for jobs where a sharp square edge would wear out faster than the job can tolerate. Its .125" radius gives the cutting edge real backbone without turning it into a full ball nose.
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 steady, predictable cutting. Uncoated and rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's a tool that balances finish quality with edge strength.
