The 4-flute geometry paired with a 30° helix promotes efficient material removal and stable cutting, helping to maintain a steady feed and finish. Powder-metallurgical HSS‑E enhances toughness and wear resistance, extending tool life under demanding milling conditions compared with conventional HSS. The 12° rake angle aids chip flow and cutting action during shoulder milling and ramping, contributing to smoother operations and reduced tool wear. With a robust Weldon 10 mm shank, this end mill delivers reliable clamping and repeatable performance in a variety of milling setups. The compact 19 mm length of cut is ideal for shallow pockets and precise feature milling, while the 69 mm overall length provides the reach needed for multi‑pass operations without compromising rigidity.
