Product Overview
The CGS Tool 440-0312 is a 1/32" diameter 4-flute solid carbide square end mill built specifically for very fine milling work, and it uses a double-end design to stretch tool life further at a size where every bit of usable edge counts. It belongs to the 440 Series, CGS Tool's double-end miniature line.
What sets this tool apart is the practical economics of a double-end build at this diameter — when one end dulls, you flip it and keep working instead of tossing the whole tool. The 30° helix keeps the cut controlled in tiny slots, miniature profiles, and flat-bottom detail, and it holds up through mild steel, stainless, cast iron, titanium, non-ferrous material, plastics, and composites.
