Omega Products ER20 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 11mm

The Omega ER20 Collet with coolant seal is a precision toolholding solution designed for high‑demand milling and drilling. It delivers ultra‑precise run‑out, with accuracy under 10 microns, and incorporates a sealed high‑pressure coolant path to keep cutting fluid where it’s needed. Built for reliable performance, it’s ideal for engineers, shop floor operators, and hobbyists who require repeatable tolerances and clean, consistent finishes.

• Ultra‑precise run‑out (<10 μm): Ensures tight alignment for accurate features and smoother surface finishes, reducing tool wear and rework.
• High‑pressure coolant seal up to 120 bar: Integrated metal seal keeps coolant on target, minimizes leaks, and supports cooler, more efficient cutting.
• Wide 3–13 mm clamping range with round‑shank tooling: Accommodates a broad range of tools securely; newer versions have no rubber nose seal—use only round shank tooling with no clamping flats to maintain seal integrity.

This combination of precision run‑out, robust high‑pressure coolant capability, and versatile clamping range helps you maintain consistent performance across jobs, reduce downtime due to leaks, and achieve dependable results with each cut. It’s a trustworthy choice for professionals aiming to streamline workflows and improve overall cutting quality.
