Omega Products ER20 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 12mm

The Omega ER20 Collet with Sealed High-Pressure Coolant is a precision tool-holding solution designed for milling and finishing tasks where dependable coolant delivery and tight run-out are essential. Compatible with standard ER20 spindles and round-shank tooling, it clamps tools from 3 to 13 mm with a repeatable, secure grip. Optimized for 12 mm ER20 tooling, it delivers consistent performance across jobs.

Designed for high‑pressure coolant systems, this collet channels coolant directly to the cutting edge while keeping chips and debris out of the spindle. It handles coolant pressures up to 120 bar, helping maintain optimal cutting temperatures and prolong tool life. The design delivers ultra-precise run-out—typically better than 10 μm—so you achieve consistent diameters and smoother finishes on every pass. Newer models feature a rubber-free nose seal, and the non-overlapping longitudinal slots minimize center leakage, enhancing reliability in demanding environments.

• High-Pressure, Sealed Cooling up to 120 bar: Delivers coolant precisely where it’s needed for improved chip evacuation and tool life, while maintaining a secure, repeatable grip on tools from 3 to 13 mm.
• Ultra-Precise Run-Out (<10 μm): Keeps tool deflection to a minimum, delivering tight tolerances, cleaner cuts, and better surface finish across cycles.
• Leak-Resistant, Rubber-Free Nose Seal with Non-Overlapping Slots: Reduces coolant loss and maintenance needs, ensuring consistent sealing and cleaner spindles in demanding machining environments.

With these characteristics, the Omega ER20 Collet helps you streamline setups, reduce rework, and extend tool life. It provides reliable, repeatable performance in challenging applications, making it a confident choice for shops that depend on precise tooling and effective cooling.
