Omega ER32 Collet (17mm) with a high-pressure coolant seal and ultra-precise run-out under 10 μm delivers dependable, repeatable performance for milling and drilling. Designed for engineers, machinists, and hobbyists who demand accurate toolholding, it helps maintain tight tolerances and clean, consistent finishes across demanding CNC cycles.

This collet clamps tool shanks from 3 to 20 mm and supports coolant pressures up to 120 bar. The seal uses an integral metal design (newer versions have no rubber seal on the nose) and a non-overlapping longitudinal slot arrangement to prevent coolant loss. For optimal sealing, use only round shank tooling with no clamping flats; tooling with flats can render the seal ineffective.

• Ultra-precise run-out (<10 μm): Keeps toolpaths stable for consistent dimensions and superior surface finish across production runs.
• High-pressure coolant seal (up to 120 bar): Maintains effective cooling and chip evacuation, extending tool life and enabling productive cutting conditions.
• Non-overlapping slot geometry: Prevents coolant leaks at the centre, delivering reliable containment and reducing maintenance.

With the Omega ER32 Collet, you gain reliable toolholding that sustains tight tolerances, improves throughput, and enhances overall cutting performance. The combination of ultra-low run-out, a robust metal-seal design, and efficient coolant containment helps you achieve repeatable results even under demanding workloads. Remember to pair with round-shank tooling and avoid clamping flats to preserve the seal’s effectiveness and long-term reliability.
