The Omega ER Collet Extension with Castle Nut (UM) and Straight Shank extends the reach of your ER40 collet system, enabling you to work longer parts without sacrificing accuracy. It’s built for a wide audience—from engineers and machinists to hobbyists and shop-floor technicians—delivering reliable performance when extra reach matters.

Its castle nut design ensures a secure, adjustable connection that stays tight under load, while the straight shank simplifies integration into a variety of tool holders and setups.

  • Secure, adjustable castle nut connection: Provides a secure and adjustable grip that lets you tighten or loosen the collet as needed, delivering reliable holding for longer workpieces.
  • Straight shank for quick, versatile integration: Fits a wide range of tool holders and setups, enabling fast, repeatable alignments and easier setup.
  • 50 mm reach with ER40 precision: Extends machining range by 50 mm while maintaining rigidity and accuracy, so longer parts can be machined in a single setup.

This extension helps you tackle longer projects, reduces setup time between operations, and supports consistent results across jobs thanks to a durable, well-engineered connection that you can trust on every run.
