Product Overview
The CGS Tool 420-1250 is a 1/8" diameter 2-flute solid carbide square end mill from the 420 Series, built with a double-end design for small slots and shallow pockets where control matters more than heavy stock removal. It's a compact, repeat-job friendly cutter.
Built on the same precision CNC equipment as CGS Tool's other general-purpose lines, it holds a 30° helix matched to a clean, predictable cut in general-purpose applications. Uncoated and rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's a practical option for small-feature work.
