Description

The Omega Products ER Collet Extension with Mini Nut and Straight Shank is a compact, dependable accessory that extends the reach and versatility of your ER collet system. It’s ideal for machinists, engineers, and hobbyists who routinely work with longer parts or tight spindle clearances, delivering extended capability without sacrificing accuracy.

Featuring a secure mini nut connection and a straightforward straight shank, this extension installs quickly into standard tool holders and ER20M configurations. Use it to extend your machining range, handle longer workpieces, and maintain stable, precise gripping throughout the cut.

  • Extended reach for longer workpieces: Adds 60 mm of reach to your ER collet setup, enabling longer parts and deeper operations while preserving rigidity and concentricity.
  • Secure mini nut connection for fast setup: The compact mini nut provides a tight, repeatable grip with quick, tool-free tightening to speed changes and minimize run-out risk.
  • Straight shank for easy integration: The straight shank design fits seamlessly with common tool holders and ER20M setups, ensuring straightforward installation and reliable alignment across machines.

By expanding reach and simplifying setup, this extension reduces handling steps and downtime, helping you complete longer projects in fewer setups. You’ll experience steadier performance, improved part accuracy on extended cuts, and a more efficient workflow across mills, CNCs, and other tooling centers.
