Omega Products ER20 Collet Set Ultra Precision is a 12-piece collection of ER20 collets designed for precision milling, routing, and small- to mid-size machining. The set covers sizes from 2 mm to 13 mm, providing versatile, single-holder compatibility for a wide range of cutting tools and applications. It’s ideal for engineers, hobbyists, and shop floors that demand reliable, repeatable performance.

With an ultra-tight specification of 5 microns run-out, this set helps deliver cleaner finishes, tighter tolerances, and longer tool life by reducing tool deflection and chatter. The foam-lined, protective case keeps every collet securely in place during transport and storage, enabling quick changes and protecting tools from damage in busy work environments.

• Ultra-precise 5 micron run-out: Ensures repeatable grip and accuracy for consistent finishes and tight tolerances across every tool change.
• 12-piece metric range 2–13 mm: Covers the most commonly used shank sizes, reducing the need for multiple sets and minimizing downtime.
• Foam-lined protective case: Secure organization and protection for each collet, supporting fast access and safe transport in busy workshops.

This ER20 collet set is designed to integrate smoothly with standard ER20 toolholders, helping you streamline workflows, reduce rework, and achieve reliable results across a broad range of milling and routing tasks. The combination of precise run-out, comprehensive size coverage, and robust storage supports consistent performance from setup to finish.
