Product Overview
The CGS Tool 440-0312-ALTiN is a 1/32" diameter 4-flute solid carbide square end mill, and at this size, the margin for error is razor thin. It's built for miniature milling work where tiny slots, delicate plunge cuts, and small flat-bottom details need a tool that won't chip out on the first pass. The double-end design gives shops a second cutting edge once the first end wears down, which matters more at this scale where replacement tools aren't cheap.
The ALTiN coating adds a layer of heat and wear resistance that helps the small cutting edge survive tougher conditions, and with a 1/16" length of cut and 1-1/2" overall length, this 440 Series cutter is purpose-built for detail work rather than material removal. It performs consistently across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites.
