Omega Products ER32 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -7mm

The Omega ER32 Collet is a coolant-sealed tool holder designed for CNC milling and drilling with round-shank tooling. Suitable for professionals and hobbyists alike, it provides secure tool retention and cleaner coolant management for reliable results.

With a clamping range of 3–20 mm and run-out under 10 μm, this collet helps keep parts to tight tolerances across a range of tools. To preserve the seal, use only round-shank tooling with no clamping flats; tools with flats can render the seal ineffective.

• Ultra-precise coolant-sealed design: Delivers run-out under 10 μm for consistent engagement and tight tolerances, reducing variance and improving surface finish.
• Wide clamping range (3–20 mm): Accommodates a broad range of tool diameters without changing collets, speeding setups and reducing downtime.
• Non-overlapping longitudinal slots: The slots are designed to not overlap at the center, preventing coolant loss and keeping your work area cleaner and more reliable.

With this ER32 coolant-sealed collet, you gain repeatable, accurate tool engagement across a broad tool size range, cleaner coolant management, and less downtime spent on maintenance or cleanup. The sealed design minimizes coolant leakage, protecting your spindle and work area, while the simple clamp interface supports quick, reliable setups. Built for busy shops and precise work, it delivers consistent performance, improved surface finish, and longer tool life across jobs.
