The Omega ER Collet Extension with Castle Nut (UM) and Straight Shank extends the reach of your ER collet tooling, enabling longer workpieces and deeper access in tight fixtures. Built for daily use in mills, lathes, and CNC setups, this 85 mm extension preserves concentricity and stability while you work.

• Secure Castle Nut Connection: The castle nut locks securely, allowing fast, tool‑free adjustment and repeatable clamping force to minimize drift during cuts.
• 85 mm Straight Shank for Flexible Mounting: Straight shank design integrates smoothly with a wide range of tool holders and machines, providing reliable, stable alignment and extended reach without cumbersome adapters.
• ER32 Compatibility with Precise Alignment: Designed for ER32 collets (C40), it maintains concentricity and stiffness across longer reaches for consistent, accurate results.

With this ER Collet Extension, you can handle longer workpieces in a single setup, reducing handling time and the chance of misalignment. The secure connection and rigid straight shank help maintain precision through demanding cuts, while easy installation keeps downtime to a minimum. Ideal for professional shops and skilled hobbyists, it expands your machining capabilities without compromising reliability or workflow efficiency.
