The Omega Products ER20 Tapping Collet is a precision tool holder designed for tapping operations. It works with standard ER20 collet chucks to provide a secure, consistent grip on tapping tools, making it ideal for machinists, engineers, and hobbyists who require reliable threaded holes.
With a 10 micron run-out, this collet keeps the tool aligned during tapping, reducing deflection and helping you achieve accurate thread forms and clean finishes across materials.
- 10 micron run-out for precise tapping: Ensures accurate alignment and minimal deflection, delivering consistent thread quality and reducing scrap.
- ER20 compatibility for secure tool grip: Designed to work with standard ER20 collet chucks, providing a reliable, repeatable grip on tapping tools across setups.
- Robust, multi-slot clamping: Segmented jaws evenly apply clamping force for dependable tool holding and repeatable results with minimal run-out drift.
In practice, this collet translates to faster setups, fewer reworks, and more consistent results across jobs. Its precise alignment and secure grip help streamline tapping workflows, improve hole quality, and build confidence in every project—from production runs to DIY builds.
