Ann Way ER40 Precision Collets deliver powerful, stable and high‑accuracy tool‑holding performance for demanding CNC and manual machining applications. Engineered for rigidity, strength and consistent concentricity, the ER40 platform is ideal for medium‑to‑large tooling diameters, heavy material removal, and applications requiring tight tolerances under load. Each collet features precision‑ground construction and a defined clamping window that allows secure gripping of slightly undersized tools, reducing chatter and improving surface finish. With a 41 mm body diameter and 46 mm length, ER40 collets offer exceptional stability for high‑torque machining, drilling, boring, and milling operations across steel, alloys, plastics, and specialist materials.
