Equipped with a cobalt‑based HSS‑E composition and a bright finish, this tool delivers improved wear resistance and heat tolerance for extended tool life in demanding materials. The 2‑flute configuration promotes efficient chip evacuation and stable cutting in finished surfaces, while the 30° helix helps reduce cutting forces and enhance surface quality. With a 15 mm full‑profile radius, it creates smooth, precise fillets and accurate transitions across intricate 3D geometries. The long reach and neck relief enable deep cavities and complex profiles without sacrificing rigidity, making it a reliable choice for prototyping and production work on copper alloys and free‑machining steels.
