Product Overview
The CGS Tool 3121 is a 3/4" diameter 3-flute solid carbide square end mill from the Storm 3100 Series, built for tough applications where a standard cutter simply doesn't feel rugged enough. It handles higher chip loads and harder production conditions with real confidence.
Its 60° high helix, heavy core, and eccentric relief design are engineered specifically for that kind of aggressive cutting. Rated for steels, stainless, cast iron, titanium, alloys, Inconel, and select non-ferrous materials, it's built for reliable chip evacuation under demanding conditions.
