Omega Products ER16 Collet Ultra Precision is a high-precision clamping accessory designed for use with ER16 collet chucks. It securely grips round shank tooling to deliver consistent, repeatable results in milling, drilling, and other precision work. With a stated 5 micron run-out, this collet helps minimize run-out-induced errors, improve finish quality, and support tighter tolerances in demanding projects. Ultra-low 5 micron run-out: Delivers exceptional concentricity for finer cuts, fewer reworks, and cleaner finishes across materials. Secure, uniform clamping for round shanks: Maintains tool alignment along the entire length of the cut, reducing chatter and extending tool life. Rugged, precision-machined construction: Built to withstand frequent use in busy shop environments while preserving grip strength and repeatable accuracy. This ER16 collet helps you streamline setups, minimize downtime, and achieve reliable, repeatable results across multiple tools and jobs. By improving concentricity and grip, it enhances overall machining performance, reduces scrap, and supports consistent finishes—so you can work faster with greater confidence.
