Omega Products ER11 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 6.5mm

The Omega ER11 Collet with integral metal seal is designed for high‑pressure coolant systems, delivering ultra‑precise tool retention with a run‑out under 10 microns. Built for engineers, machinists, and hobbyists who demand reliable performance in milling and drilling, it securely holds 6.5 mm round shanks while withstanding coolant pressures up to 120 bar for clean, accurate cuts.

• Ultra-precise run-out: Provides <10 μm accuracy to minimize tool deflection and deliver consistent, high‑quality finishes across materials and speeds.
• High‑pressure coolant seal: Integral metal seal supports coolant pressures up to 120 bar and, with non‑overlapping longitudinal slots, prevents coolant loss at the nose for cleaner cuts and less downtime.
• 3–7 mm clamping range: Broad compatibility with common small‑to‑mid size tooling, enabling versatile setups; for optimal performance, use only round shank tooling with no clamping flats to maintain the seal.

This collet design combines durable materials and precision engineering to reduce setup time, improve repeatability, and extend tool life in demanding machining environments. You can count on stable, repeatable hold during high‑speed milling and drilling, even with challenging materials, thanks to the sealed interface and tight tolerances.
