Omega Products ER40 Collet Ultra Precision is a high-precision toolholding solution designed for ER40 collet chucks. It clamps round shank tooling with exceptional concentricity, making it ideal for milling, drilling, and finishing operations where precision matters.
With a 5 micron run-out specification, these collets deliver consistent, repeatable performance that helps you achieve tighter tolerances and smoother finishes in demanding machining tasks.
- Ultra-precise 5 micron run-out: Ensures concentric tool rotation for accurate cuts, reducing part variability and improving surface finish.
- ER40-compatible collet design: Optimized to securely clamp round shank tooling in ER40 collet chucks, minimizing slip at high speeds.
- Rugged, precision-ground construction: Built for durability and sustained accuracy, delivering reliable performance in busy shop environments.
This collet system helps you maintain tight tolerances, cut setup time, and achieve consistent results across parts. By reducing run-out and improving grip, it supports faster, more confident machining across a wide range of applications.
