The Benchmark Carbide 35050020C5 (also marked 350-50020-C5) is a new, USA-made solid carbide single-end square end mill specifically engineered for aluminum and non-ferrous machining. It features a 3-flute geometry with a 1/2 in cutting diameter, 1/2 in shank diameter, 1-1/4 in length of cut, and approximately 3 in overall length, as decoded directly from the label "1/2 X 1/2 X 1-1/4 X 3." The tool is coated with ZrN (Zirconium Nitride), a gold-colored PVD coating that provides low friction, exceptional chip adhesion resistance, and extended tool life in aluminum, brass, copper, and other non-ferrous materials. Manufactured by Benchmark Carbide (a division of Custom Carbide Corporation) in the USA, this end mill is compatible with standard 1/2 in collet chucks, end mill holders, and hydraulic/shrink-fit toolholders on CNC machining centers and manual mills.
