Omega Products ER20 Collet Ultra Precision - 5 Micron Run-Out - 3.5mm - 2.5mm

The Omega Products ER20 Collet Ultra Precision is designed for exacting toolholding in ER20 collet chucks, making it ideal for machinists, engineers, tradespeople, hobbyists, and shops that demand tight tolerances. It clamps round-shank tools with exceptionally low run-out, helping you achieve consistent geometry and superior surface finishes across jobs.

• 5 µm run-out for ultra-precise machining: Delivers exceptional concentricity to minimize deviation during cuts, improving accuracy, finish quality, and tool life.
• 2.5–3.5 mm shank compatibility: Covers a common small-diameter tool range, enabling fast tool changes and reducing the need for multiple collets in your setup.
• Durable, reliable ER20 precision design: Built to withstand daily workshop use while maintaining grip integrity and repeatable performance over time.

This collet supports a streamlined workflow by delivering repeatable clamping, reducing setup time, and providing confidence in every operation—from prototyping to production milling. With its tight run-out and robust construction, you can expect consistent results, fewer reworks, and a more efficient path from concept to finished part.
