Omega Products ER16 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -9mm

The Omega ER16 Collet Coolant Sealed is a precision clamping solution for milling and drilling. It’s designed for a broad audience—from engineers and machinists to buyers and hobbyists—who need reliable tool retention and efficient coolant management in everyday work.

With a tight run-out tolerance of less than 10 microns, this collet delivers repeatable seating and consistent results. The coolant-sealed design helps keep tooling cool and surfaces clean, so you can work more efficiently with fewer reworks.

• Ultra-precise run-out with updated seal design: Delivers less than 10 microns run-out for repeatable tool seating, and newer versions remove the rubber nose seal for easier maintenance and cleaner operation.
• Coolant retention via non-overlapping slots: The longitudinal slots do not overlap at the centre, preventing coolant loss and keeping coolant where it’s needed for tool life and finish quality.
• Versatile clamping range for 3–10 mm round tooling: Supports a wide range of round-shank tools; to maintain the seal, use only round shanks with no clamping flats—shanks with flats will render the collet ineffective.

By combining precise gripping with reliable coolant management in a compact, easy-to-use package, this collet streamlines setup, reduces downtime, and helps you achieve consistent, high-quality results across a wide range of milling and drilling tasks. It’s a dependable choice for a busy shop or workshop that relies on repeatable performance and durable construction.
