• Applications: shoulder milling, slot milling, ramping
• Compatible materials: free‑machining and plain carbon steel, copper and copper alloys

The tool’s 5-flute design provides a balance between material removal and surface finish, making it well-suited for precise slots and shoulders without compromising accuracy. The 30° helix promotes effective chip flow and steady cutting action, while the 12° rake angle helps reduce cutting forces during shoulder milling, supporting better dimensional stability. Powder-metallurgical HSS‑E offers improved wear resistance and toughness, extending tool life when working with tougher steels and copper alloys. The 53.5 mm reach with neck relief adds accessible depth to reach features tucked behind pockets, yet the rigid Weldon shank ensures consistent clamping and minimal runout. Meeting DIN 844 K ensures compatibility with a wide range of standard holders for reliable interchange in production environments.
