This long‑series drill excels in producing clean slots and precise shoulders thanks to its 3‑flute geometry and 30° helix, which promotes efficient chip evacuation and smoother cutting. The 12° rake angle supports controlled cutting action in metals, while the bright, cobalt‑enhanced HSS‑E composition provides wear resistance and durability under demanding milling conditions. The 6 mm Weldon shank ensures secure clamping for repeatable results across setups, and DIN 844 L compatibility helps with fast, problem‑free tool changes in standard holders. Ideal for engineers and machinists aiming for accurate, repeatable slot and shoulder milling in common industrial alloys.
