Description

The Omega Products ER Collet Extension with Mini Nut and Straight Shank is a compact, dependable accessory designed to expand the reach of your ER collet system. Sized for the C20 ER20M setup and measuring 50 mm in length, this extension lets you tackle longer workpieces without sacrificing accuracy or stability. Built for both shop floors and home workshops, it helps you extend your machining envelope with confidence.

  • Secure Mini Nut Connection: Fast, tool-free tightening and a compact interface that maintains consistent clamping force, reducing setup time and keeping you on schedule.
  • 50 mm Straight Shank for Easy Setup: Straight, compatible shank design ensures smooth insertion into standard tool holders and reliable alignment in milling or drilling setups.
  • Rugged, Precision-Grade Construction: Built to endure daily use, delivering durable performance with minimal wear and stable accuracy over extended work sessions.

With a robust extension length and a user-friendly mini nut, this ER collet extension helps you process longer parts in a single setup, saving time and reducing the need for multiple repositionings. The combination of a secure connection, straightforward fit, and durable construction translates to more consistent results, less downtime, and greater confidence in your machining workflow for both professional projects and hobbyist applications.
