Precision, reliability, and repeatable performance come together in the Omega ER50 Collet Standard Precision. This ER50 collet is designed to clamp round tooling securely in an ER50 collet chuck, delivering consistent grip and concentricity across every cut. With a run-out specification of just 10 microns, it minimizes tool deviation and vibration, helping you achieve clean surfaces and tighter tolerances in general machining tasks.

• Concentric performance: 10 µm run-out ensures your tool stays true to center, reducing run-out error in milling, drilling, and finishing.
• Uniform gripping action: a segmented design distributes clamping force evenly around the tool shank for repeatable results.
• Ready for ER50 chucks: engineered to integrate smoothly with standard ER50 collet chucks, enabling quick changes and dependable seating.
• Versatile, general-purpose use: ideal for everyday machining of various materials, from aluminum to steels, where steady grip matters more than variant-specific features.
• Durable construction: precision-machined from robust steel to withstand shop conditions and maintain accuracy over time.

Who should consider this ER50 Collet? Shops and individuals performing routine milling and drilling with round tools that require high concentricity, especially when tight tolerances and smooth finishing are essential. It’s a practical choice for production tasks that value reliability and straightforward compatibility over complex configurations.

Practical tips: keep mating surfaces clean to maintain accurate seating, avoid over-tightening which can distort the collet, and periodically verify run-out with a dial indicator to ensure ongoing performance. Store with care to preserve the precise tolerances that make this collet a dependable workhorse in the shop.
