Omega Products ER40 Collet Ultra Precision- 5 Micron Run-Out - 10mm - 9mm

The Omega Products ER40 Collet Ultra Precision is a precision tool holder designed to clamp round shank tooling in an ER40 collet chuck. Its ultra-low run-out makes it ideal for high-precision milling, drilling, and finishing work, delivering consistent accuracy across jobs. This collet is geared toward machinists, toolmakers, and serious hobbyists who demand dependable performance in their setups.

With a 5 micron run-out, it helps you achieve tighter tolerances and smoother finishes, reducing the need for rework and enabling more repeatable results across projects.

• Ultra-low run-out (5 microns): Delivers exceptional concentricity for high-precision milling and drilling, reducing cutter deflection and improving part tolerances.
• ER40 chuck compatibility with round shank tools: Optimized for repeatable grip in standard ER40 collet chucks, enabling quick setup and reliable clamping without chatter.
• Durable, precision-ground construction: Hardened steel with tightly machined surfaces resists wear and maintains accuracy over time in demanding workshop environments.

This collet supports smoother workflows, shorter setup times, and more consistent results, helping you achieve better surface finishes and tighter tolerances in a wide range of machining tasks. Its combination of precise run-out, reliable ER40 compatibility, and durable build gives you confidence to tackle precision work day after day.
