Vertex ER straight‑shank collet chucks are designed to provide precise, rigid, and versatile toolholding for manual milling machines, CNC setups, and custom fixtures. Their cylindrical straight‑shank design makes them ideal for mounting in drill chucks, end‑mill holders, boring heads, sleeves, or custom clamping blocks. With options in ER11 and ER16 sizes and a range of shank diameters and lengths, these holders offer excellent accessibility for fine milling, engraving, light‑to‑medium‑duty cutting, and applications where limited space or deep‑reach tooling is required. Precision ground for concentricity and consistent clamping force, Vertex ER straight‑shank chucks give machinists dependable performance and flexibility across general machining, prototyping, and fixture building environments.
