Product Overview
The CGS Tool 140-3125 is a 5/16" diameter 4-flute solid carbide square end mill from the 140 Series, sized for everyday CNC milling where slots, shoulders, and finishing passes need to stay clean and predictable. It's the kind of tool that gets reached for constantly precisely because it doesn't specialize in any one job.
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 controlled, dependable cutting. Uncoated and rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's a genuine shop-standard tool.
