Omega Products ER16 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 6mm

The Omega ER16 Collet Coolant Sealed Ultra Precision is a compact, high-performance tool holder designed for demanding milling and drilling tasks. Built for 6 mm tooling shanks and a clamping range of 3–10 mm, it delivers sub-10 μm run-out to help you achieve repeatable, precise cuts with every part. The sealed design keeps coolant where it belongs, supporting efficient cooling and steady performance in tough environments.

• Ultra-precise run-out (<10 μm): Ensures tight tolerances and consistent part finishes, reducing rework and improving overall accuracy.
• High-pressure coolant sealing up to 120 bar: Integral metal seal maintains effective cooling and grip under demanding cutting conditions, even at elevated coolant pressures.
• Non-overlapping slot design for coolant retention: Longitudinal slots are arranged to prevent coolant loss at the center, enhancing seal reliability and reducing maintenance needs.

This collet is engineered to perform reliably in high-pressure cooling setups while providing accurate tool alignment and strong grip across a versatile 3–10 mm tool range. Newer versions replace the nose rubber seal with a durable metal seal, further improving longevity in coolant-rich operations. For best sealing performance, please ensure you are using solely round shank tooling with no clamping flats, as tools with flats will render the seal ineffective.
