Omega Products ER16 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 3mm

The Omega ER16 Collet Sealed Ultra Precision is a coolant-sealed tool holder designed for high-precision CNC milling and drilling. It supports a 3–10 mm tool range and delivers run-out under 10 μm, enabling consistently accurate results at speed. Built for demanding environments, its integral metal seal withstands coolant pressures up to 120 bar, keeping the cutting zone cool, clean, and productive.

Newer versions have no rubber seal on the nose, and the collet uses non-overlapping longitudinal slots at the centre to prevent coolant loss. For optimal sealing, use only round-shank tooling with no clamping flats; tools with flats will render the seal ineffective.

• Ultra-precise run-out (<10 μm): Delivers exceptional positional accuracy during high-speed milling, reducing tool vibration and improving surface finish on small-diameter tools.
• High-pressure coolant sealing up to 120 bar: An integral metal seal and carefully arranged slots prevent coolant leakage, keeping the cutting zone cool and debris-free for longer tool life.
• 3–10 mm round-shank tooling compatibility: Provides secure, repeatable tool holding for standard small-diameter tooling; ensure round shanks with no clamping flats to maintain the seal and performance.

With these features, you gain reliable, repeatable results that improve workflow and reduce downtime. The combination of ultra-low run-out and robust coolant sealing helps you maintain tight tolerances, achieve cleaner finishes, and extend tool life, even under demanding cycles and tough materials. This collet is built to withstand busy shop conditions, delivering consistent performance and confidence across multiple jobs.
