The Omega ER40 Tapping Collet is a precision tool holder built for tapping operations. Sized for ER40 collet chucks with a 4.5 mm x 3.4 mm configuration, it delivers a 10 micron run-out for exceptional alignment and minimal deflection during cutting. This combination provides a reliable grip on tapping tools and supports repeatable, clean threads.

• 10 micron run-out for precise tapping: keeps the tool aligned and minimizes deflection during every pass, helping you produce clean, accurate threads.
• ER40 compatibility with secure gripping: designed to fit standard ER40 collet chucks, delivering a secure, repeatable grip on tapping tools and reducing tool slip.
• Durable, precision-engineered construction: built to tight tolerances to maintain accuracy over long use, resisting wear in demanding tapping applications.

By delivering exceptional alignment and a secure grip, this ER40 tapping collet helps you achieve consistent thread quality, reduce scrap and rework, and keep tapping operations running smoothly across jobs. The low 10 micron run-out, confirmed ER40 compatibility, and durable, precision-tolerant design translate into faster setups, repeatable results, and higher overall productivity for engineers, machinists, and shop teams.
