Product Overview
Everyday milling doesn't need a specialty tool, and the 420-2500 fills that everyday role well. This 1/4" diameter 2-flute square end mill comes with a double-end design, so shops get two usable cutting edges from a single tool before it needs replacing.
That extra tool life matters most on repeat production jobs where the same cutter runs the same operation over and over. With a 30° helix and uncoated carbide body, the 420-2500 handles clean slots, accurate profiles, light plunge cuts, and flat-bottom features across mild steel, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites without any special setup considerations.
