This end mill combines a robust powder-metallurgical HSS-E core with a bright finish for improved wear resistance and smoother chip flow. The 30° helix aids efficient chip evacuation at small diameters, while the 12° rake angle supports stable cutting during shoulder milling and ramping operations. The flatted 6 mm Weldon shank provides secure seating in compatible holders, helping maintain concentricity and precision during delicate milling tasks. Ideal for workshops and production environments that require dependable, repeatable small-diameter milling performance on a range of common metals.
