Omega Products ER40 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -22mm

The Omega ER40 Collet Coolant Sealed Standard Precision is a high-accuracy toolholding accessory designed for milling and turning tasks that demand clean cooling and tight tolerances. It provides a compact, reliable interface between your machine spindle and cutting tool, helping you achieve consistent results across jobs.

This coolant-sealed collet delivers <10 μm run-out, helping you maintain precise diameters and smooth finishes. It features a practical clamping range of 3–26 mm, making it versatile for a wide range of tooling sizes. Note that newer versions have no rubber seal on the nose. For optimal performance, please ensure you are using solely round shank tooling with no clamping flats—tools with flats will render the seal ineffective.

• Near-zero run-out (<10 μm): Ensures precise tool engagement and repeatable tolerances, improving part accuracy and surface quality.
• Coolant-sealed design with non-overlapping slots: Central-slot geometry prevents coolant loss, keeps the cutting zone well lubricated, and reduces mess and cleanup.
• Wide 3–26 mm clamping range for round-shank tooling: Flexible compatibility across common tool diameters; to maintain the seal, use round shanks with no clamping flats.

Together, these features support faster setups, cleaner coolant management, and consistently reliable performance across a range of tooling options. The result is greater workflow efficiency, reduced downtime between jobs, and dependable results on every part you produce.
