The tool’s extra-short series minimizes deflection in narrow slots and shallow pockets, helping you achieve accurate shoulders and consistent slot dimensions. The combination of powder-metallurgical HSS-E and a durable Alcrona Primax coating delivers improved wear resistance and longer tool life, even under demanding milling conditions. With its robust 10 mm Weldon shank and flat section, it stays securely seated in holders, reducing runout for precise, repeatable results across automotive, aerospace, and general manufacturing applications.
