The Omega Products ER Collet Extension with Mini Nut and Straight Shank is a compact accessory that extends the reach of your ER collets, enabling you to hold longer, more complex workpieces with confidence. Designed for machining centers, milling setups, and workshop benches, it delivers stable, precise performance in tight clearance areas.

Featuring a secure mini nut design and a straightforward straight shank, this extension locks into your existing ER8M system (C10 ER8M x 100mm) quickly and securely, so you can tighten or loosen the collet with minimal effort and minimal runout. It’s built to withstand frequent use in demanding environments while preserving alignment and rigidity.

• Secure Mini Nut Connection: Delivers a tight, repeatable grip on ER collets with easy tightening and loosening, reducing setup time and the risk of slippage during machining.
• Rigid Straight Shank for Easy Mounting: Fits standard tool holders and setups, providing stable alignment and quick, clean insertions to minimize runout and tool chatter.
• Extended Reach for Longer Workpieces: 100 mm extension length expands your machining envelope without sacrificing accuracy or rigidity.

With the ER Collet Extension, you can tackle longer parts and more challenging geometries without changing your base setup. The reliable connection and solid alignment help you reduce downtime, improve surface finish, and maintain tight tolerances across your workflow—from roughing to finishing. Whether you’re in a high-output production line or a hobbyist shop, this extension adds versatility and confidence to every project.
