The Omega ER32 Collet with High-Pressure Coolant Sealing is a precision toolholding solution designed for milling and drilling where coolant performance and tight runout matter. It’s ideal for engineers, machinists, and shop teams that demand repeatable part quality and reliable tool support in demanding manufacturing environments.

Key specifications at a glance include a clamping range of 3–20 mm and an 18 mm size, with ultra-precise run-out under 10 microns. It’s built to handle high-pressure coolant up to 120 bar. Newer versions feature a metal seal on the nose (no rubber seal) to improve durability, while the non-overlapping longitudinal slots help prevent coolant loss. For optimum performance, use solely round-shank tooling with no clamping flats to maintain the seal.

• Sub-10 μm run-out for repeatable accuracy: Ensures tight concentricity for consistent toolpaths, improved surface finish, and tighter part tolerances across jobs.
• Integral metal seal for high-pressure cooling (up to 120 bar): Delivers coolant directly to the cutting zone, reducing heat input, extending tool life, and maintaining stable performance. Newer versions have no rubber seal on the nose for enhanced durability.
• Non-overlapping slots with round-shank tooling: Longitudinal slots do not overlap at the center to minimize coolant loss, and the design is intended for round-shank tooling with no clamping flats to ensure a reliable, leak-free seal.

This ER32 collet setup helps you streamline operations by delivering reliable coolant performance, precise toolholding, and consistent results across multiple tools and shifts. With a broad 3–20 mm clamping range, 18 mm size, and robust high-pressure cooling, you’ll experience reduced downtime, cleaner finishes, and more predictable performance in demanding milling and drilling tasks.
