Omega Products ER16 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 7mm

The Omega ER16 Collet with coolant seal is a precision toolholding solution built for engineers, machinists, and hobbyists who demand reliable cooling and repeatable accuracy in milling and drilling. It supports 7 mm tooling within a 3–10 mm clamping range and delivers ultra-smooth performance with run-out under 10 microns, helping you achieve cleaner cuts and longer tool life even under demanding conditions.

• Ultra-precise run-out: Achieves under 10 μm accuracy to ensure stable tool engagement, better surface finish, and reduced chatter across a range of speeds and feeds.
• High‑pressure coolant sealing: Integral metal seal designed for coolant delivery up to 120 bar, maintaining effective cooling and chip evacuation; newer versions use a metal-to-metal nose seal (no rubber) for improved durability in tough jobs.
• Round‑shank tool compatibility: Optimized to seal properly with round shank tooling only; avoid tooling with clamping flats to preserve the seal and prevent coolant leakage during operation.

This collet is purpose-built to keep coolant where it’s needed most, reduce downtime from tool changes, and deliver consistent performance through a wide 3–10 mm tooling range. By combining a robust sealing design with tight run-out control, it helps you achieve precise, repeatable results while maintaining efficient cooling and extended tool life in challenging machining tasks.
