This end mill is built for reliable, repeatable results in everyday machining. The powder‑metallurgy HSS‑E composition delivers improved wear resistance and toughness, helping maintain sharpness across longer runs compared with conventional HSS. The 4‑flute geometry provides a balance of strength and good chip clearance, while the 30° helix and 12° rake optimize cutting action for clean shoulders and slots. The flatted 20 mm Weldon shank ensures a positive drive in standard tool holders, reducing slippage during demanding operations. With dimensions tuned for DIN 844 K compatibility, it fits neatly into existing setups and workflow.
