Omega Products ER16 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 4mm

The Omega ER16 Collet is a coolant-sealed, ultra-precision toolholder built for demanding machining environments. It clamps 4 mm tooling within a 3–10 mm range and is designed to deliver consistent, repeatable results across milling and drilling tasks. It's a versatile choice for engineers, machinists, tradespeople, and serious hobbyists who need reliable grip and tight tolerances in a compact ER16 package.

Newer versions feature no rubber seal on the nose for longer life and easier maintenance. The collet’s integral metal seal works with high-pressure coolant up to 120 bar, while the non-overlapping longitudinal slots at the center help prevent coolant loss, keeping your cutting zone cool and under control.

• Ultra-precise run-out: Delivers less than 10 μm run-out for repeatable tool positioning and superior surface finish on every pass.
• High-pressure coolant seal with integral metal seal: Sealed performance up to 120 bar to maximize cooling and chip removal without leaking or loss of pressure.
• Leak-resistant slot design for round tooling: Longitudinal slots do not overlap at the center, preserving the seal; use with round shank tooling (no clamping flats) to maintain reliability and performance.

This combination of precision, sealed cooling, and robust construction translates to steadier workflows, reduced downtime from coolant leaks, faster cycles, and consistently high-quality results. With reliable clamping in the 3–10 mm range and tight alignment at under 10 μm, the ER16 Collet helps you achieve better productivity and longer tool life across challenging milling and drilling applications.
