Product Overview
The CGS Tool M142-020-BN-ALTiN is a 2mm diameter 4-flute solid carbide ball end mill from the Metric End Mills line, built for shops standardized on millimeter tooling who still want the same ball-nose precision as the imperial 142 Series. At this diameter, it's strictly a detail and finishing tool.
The 1mm ball radius and 30° helix are held to the same precision CNC grinding standard as CGS Tool's other General Purpose lines, and the ALTiN coating is genuinely useful here since 2mm carbide runs hot fast under any real load. Rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's a small tool with a surprisingly broad job list.
