Product Overview
The CGS Tool M142-040-BN is a 4mm diameter 4-flute solid carbide ball end mill from the 142 Series Metric line, sized for metric profile and contour milling. Its 2mm radius gives a smooth rounded form for surface finishing and small 3D profile work.
Built on the same precision CNC equipment as CGS Tool's other general-purpose lines, it holds a 30° helix matched to steady general-purpose cutting. Uncoated and rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's useful when clean radius control is needed on metric parts.
