Learn more about Klarna
Description
The Omega ER20 Tapping Collet is a precision tool accessory designed for tapping operations. It’s built for engineers, machinists, tradespeople, hobbyists, and anyone who needs clean, accurate threads. The collet’s ER20 size ensures compatibility with standard collet chucks to hold tapping tools securely, with a 5mm x 4mm interface specification to help identify the proper fit.
- 10 micron run-out: Delivers exceptional alignment with just 10 microns of run-out, reducing deflection during tapping for tighter, more repeatable threads.
- ER20 compatibility: Fits standard ER20 collet chucks for quick setup and reliable tool seating, helping you integrate this collet into your existing tooling ecosystem.
- Secure, reliable gripping for tapping tools: Holds tapping tools firmly to prevent slips and maintain concentricity under cutting loads.
This combination supports consistent, high-quality tapping results, minimizes rework from misalignment, and keeps your workflow efficient across jobs.
