Product Overview
The CGS Tool 440-2188 is a 7/32" diameter 4-flute solid carbide square end mill from the 440 Series, sized for shops that need tighter slots and smaller walls without dropping into micro-tool territory. It sits in that useful middle ground between a standard-size cutter and a true precision micro tool.
Built on the same precision CNC equipment as CGS Tool's other general-purpose lines, it holds a 30° helix and a double-end design that stretches its usable life. Uncoated and rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's a dependable choice for controlled, smaller-scale work.
