Product Overview
The CGS Tool 140-3125-ALTiN is a 5/16" diameter 4-flute solid carbide square end mill built specifically for general-purpose roughing and finishing where the same tool needs to handle both jobs. It belongs to the 140 Series, CGS Tool's standard general-purpose line.
What sets this tool apart is the ALTiN coating on top of the reliable 140 Series geometry — a small addition that pays off in tougher cutting conditions where an uncoated tool would dull faster. Running a 30° helix, it holds up through mild steel, stainless, cast iron, titanium, non-ferrous material, plastics, and composites.
