Product Overview
The CGS Tool 840-1003 XL is a 1" diameter 4-flute solid carbide square end mill built for the jobs where standard-length tools simply can't reach. With a 6" length of cut and 9" overall length, it's made for deep profiles, tall side walls, and extended slotting where the feature runs far below the surface.
Reach like this puts real demands on a tool, and the 30° helix is what keeps chips clearing consistently over that much cutting length instead of packing up halfway down. Left uncoated, this 840 Series cutter holds up across mild steel, stainless, cast iron, titanium, non-ferrous stock, plastics, and composites.
