Omega Products ER16 Collet Ultra Precision is a high-precision toolholding component designed to clamp round shank tools in an ER16 collet chuck, delivering consistent, repeatable results in precision machining. With a 5 micron run-out and a tool shank range of 4–5 mm, this collet helps maintain concentricity across milling, drilling, and finishing tasks, enabling tighter tolerances and cleaner finishes. 5 Micron Run-Out: Delivers exceptionally tight run-out to minimize tool deflection and maximize concentricity, helping you achieve accurate cuts and smoother surface finishes. ER16 Collet Chuck Compatibility: Designed to drop into standard ER16 collet chucks for quick setup and repeatable clamping, supporting consistent results across tools. Durable, Precision Machining: Built for longevity with a robust, precision-machined surface that resists wear and maintains accuracy through repeated tool changes. With these features, you gain tighter tolerances, reduced rework, and faster setups, empowering you to improve part quality, shorten cycle times, and keep production moving with confidence.
