Product Overview
Right at the near-half-inch mark, the 140-4531 fills a practical gap for shops that need something just under 1/2" without stepping up to the full size. This 29/64" diameter 4-flute square end mill handles slotting, profiling, plunge cutting, and side wall milling where a sharp square-end finish matters.
Precision cutting edges and a 30° helix keep this 140 Series cutter consistent, moving chips out steadily across common shop materials. Uncoated and single-end, it's a dependable choice for mild steel, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites in everyday CNC work.
