Omega Products ER32 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -3mm

The Omega ER32 Collet is a coolant-sealed, standard-precision toolholding solution designed to securely grip round-shank cutting tools from 3 to 20 mm. With an exceptional run-out of under 10 microns, it helps you maintain tight tolerances and repeatable results in milling, drilling, and precision machining tasks. Built for engineers, machinists, hobbyists, and workshop professionals, it delivers reliable performance and clean tool changes in a wide range of applications.

Designed to minimize coolant leakage and keep your work area cleaner, this collet uses a precision slot geometry where the longitudinal slots do not overlap at the center. Newer versions omit the rubber nose seal, relying on the intact geometry to maintain sealing performance. For optimal results, ensure you are using solely round shank tooling with no clamping flats, as tools with flats will render the seal ineffective.

• Exceptional precision with sub-10 μm run-out: Delivers highly consistent grip and improved part quality across repetitive operations, enhancing accuracy and finish consistency.
• Reliable coolant sealing design: Slot geometry minimizes coolant loss at the nose, with newer versions eliminating the rubber seal for reduced wear and simpler maintenance.
• Wide clamping range (3–20 mm) for round shanks: Versatile enough to handle a broad range of tooling sizes while providing secure, repeatable toolholding when used with round shank tooling that has no clamping flats.

This collet set is designed to streamline your workflow: it holds your tools firmly, reduces downtime from leaks or tool changes, and delivers dependable performance across demanding machining tasks. Whether you’re upgrading a shop’s capabilities or equipping a portable setup, it provides precise, clean, and efficient toolholding that helps you achieve better results faster.
