Product Overview
The CGS Tool 140-5625-ALTiN is a 9/16” diameter 4-flute solid carbide square end mill from the 140 Series, stepping up into the larger-diameter range where rigidity and heat management both start to matter more. It's built for shops that need a bigger square-end tool without moving into a specialty line.
It's ground on the same precision CNC equipment as the rest of CGS Tool's General Purpose range, holding a 30° helix across all four flutes, and the ALTiN coating helps it shed heat at this larger diameter where sustained cuts generate more friction. Rated across mild steels, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites, it's a workhorse-sized tool built for workhorse jobs.
