Omega Products ER32 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 20mm

The Omega ER32 Collet with coolant seal delivers precision and reliability for high‑demand milling. Designed for tool shanks in the 3–20 mm range, it provides ultra‑tight run‑out and a robust coolant path to keep cutting edges cool under pressure. Ideal for engineers, machinists, and hobbyists who need consistent, repeatable results in challenging milling tasks.

• Ultra‑precise run‑out: Achieves less than 10 μm run‑out for accurate tool guidance and smooth, repeatable finishes across parts.
• High‑pressure coolant sealing: Integral metal seal supports coolant pressures up to 120 bar, directing cooling precisely to the cutting edge for longer tool life and cooler operation.
• Leak‑resistant nose design and proper tooling compatibility: Longitudinal slots do not overlap at the centre to prevent coolant loss; newer versions use a metal‑to‑metal seal with no rubber nose seal. For best results, use only round shank tooling with no clamping flats—tools with flats will render the collet ineffective.

With its combination of ultra‑tight run‑out, robust high‑pressure coolant sealing, and a design that minimizes coolant leakage, this ER32 collet supports efficient setups, reduces downtime, and delivers consistent performance across demanding milling applications. It’s a reliable choice for achieving precise, repeatable results while maintaining clean, controlled cooling.
