The Omega ER32 Collet with high‑pressure coolant seal is built for precision milling and drilling where toolholding accuracy and effective cooling matter. This sealed collet delivers ultra‑low runout and dependable coolant delivery, making it ideal for engineers, machinists, tradespeople, hobbyists, and shops that demand consistent results.

Newer versions have a metal nose seal with no rubber seal, designed to minimize leak paths. To preserve the seal’s integrity, use only round shank tooling with no clamping flats; tooling with flats will render the collet ineffective. The system supports a clamping range of 3–20 mm and tolerates coolant pressures up to 120 bar, keeping coolant where it’s needed most.

• Ultra‑precise runout (<10 μm): Delivers tighter tolerances for consistent guidance and superior surface finishes across milling and drilling tasks.
• High‑pressure coolant seal (up to 120 bar): Maintains coolant delivery at the cutting edge, improving cooling, reducing thermal distortion, and extending tool life.
• Wide clamping range 3–20 mm with round shank tooling: Flexible for common tools and quick setup, provided you use round shanks with no flats to preserve the seal’s effectiveness.

This combination of precision, sealed cooling, and versatile clamping translates to more reliable, repeatable results, shorter cycle times, and fewer reworks. With durable construction and a design proven for demanding environments, the Omega ER32 Collet gives you confidence to tackle precision jobs on both production lines and workshop projects alike.
