Description

The Omega Products ER Collet Extension with Castle Nut (UM) and Straight Shank is a precision accessory that extends the reach of your ER32 collet system, enabling you to machine longer parts and access deeper work areas with confidence.

Designed for reliability in busy shops, its castle nut delivers a secure, adjustable connection, while the straight shank ensures easy mounting in a broad range of tool holders and setups.

  • Secure, adjustable castle-nut connection: Quick, tool-free tightening and reliable grip keep the collet aligned under load, reducing setup time and preventing slips during demanding cuts.
  • Extended 100 mm reach for longer workpieces: Adds a full 100 mm of reach to your ER32 setup, expanding your machining envelope without swapping tooling while preserving stiffness and accuracy.
  • Straight shank for versatile mounting: Easy insertion into a wide variety of tool holders and fixtures, improving setup speed and compatibility with existing equipment.

This extension helps you tackle longer parts in a single setup, minimize fixture changes, and maintain tight tolerances across extended operations. The durable construction and secure connection reduce downtime and keep your workflows running smoothly, enabling faster cycles and consistently better finishes on longer jobs.
