Description

The Omega Products Shrink Fit Collet Extension with Straight Shank provides a compact, high-precision way to extend the reach of your cutting tools. Designed for engineers, technicians, and hobbyists, this 25mm extension length lets you access deep features without repositioning the entire setup, while the shrink-fit mechanism ensures a secure grip on 12mm shank tools.

Built for reliability in demanding operations, the cylindrical shank installs quickly into compatible tool holders and machines, delivering consistent alignment and rigidity. The shrink-fit design minimizes runout, helping you achieve clean holes, smooth milling, and repeatable results even under tough workloads.

  • Tight, secure shrink-fit grip: The shrinking action clamps your 12mm shank tool firmly, eliminating play and reducing tool deflection for precise cuts and repeatable performance.
  • Extended reach with enhanced rigidity: 25mm extension length provides deeper access to features while maintaining stiffness to preserve accuracy during drilling and milling.
  • Easy installation and broad compatibility: Cylindrical shank fits a wide range of tool holders and machines, enabling quick setup with minimal downtime and fewer tool changes.

This extension helps you complete complex parts faster by letting you reach deeper features in a single setup, reducing tool changes and set-up time. With secure tool retention and stable performance, you’ll see cleaner holes, better surface finishes, and improved overall productivity across drilling, milling, and finishing tasks.
