The Omega ER40 Tapping Collet is designed for precision tapping operations, delivering exceptional positional accuracy with a run-out of just 10 microns. This ultra-tight tolerance helps keep threads true and tapping tools stable, reducing deflection and improving overall thread quality.

Sized for ER40 collet chucks and built for reliable performance, this collet provides a secure gripping mechanism for tapping tools. Dimensions: 6.3mm x 5mm.

• Ultra-low 10 µm run-out: ensures precise alignment and minimizes deflection during tapping, delivering consistent thread quality and fewer scrap parts.
• ER40 compatibility with secure grip: works with standard ER40 collet chucks to provide a stable, slip-free hold on tapping tools, reducing chatter during heavy cuts.
• Durable, precision-ground construction: crafted for repeated use in busy shops, maintaining accuracy over time with minimal maintenance and replacement.

With this collet, you’ll experience faster setup, repeatable results, and fewer retries due to misalignment. The combination of low run-out and reliable ER40 compatibility supports smoother tapping workflows, cleaner finishes, and improved productivity across a range of materials and applications.
