Omega Products ER16 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -7mm

The Omega ER16 Collet is a coolant-sealed, standard precision collet designed for round-shank tooling. It delivers sub-10 μm run-out for consistently accurate milling, with a clamping range of 3–10 mm to cover a wide range of common tools. Newer versions feature a rubber-seal-free nose and a non-overlapping slot arrangement to help prevent coolant loss and maintain dependable sealing performance.

• Sub-10 μm run-out for repeatable precision: enables tight tolerances and smooth finishes across repeated passes, reducing part Variability and improving overall surface quality.
• Coolant-sealed design with non-overlapping slots: the slot geometry prevents coolant from leaking at the centre, keeping the work area cleaner and protecting the spindle; newer versions have no rubber seal on the nose for simpler maintenance.
• 3–10 mm clamping range for round shanks: provides secure, consistent grip on round tooling without clamping flats, supporting reliable alignment and easy tool changes.

This collet solves common milling challenges by combining precise run-out with a reliable coolant seal and broad tool compatibility. Use only round shank tooling (no clamping flats) to maintain the seal, and you’ll experience dependable performance, fewer leaks, and smoother workflow from setup to finished part.
