Meet the Omega ER50 Collet Standard Precision, a trusted workholding solution engineered for dependable accuracy in everyday machining. Built to clamp round tooling and workpieces with exceptional concentricity, this ER50 collet delivers a reliable grip that you can count on from prototyping through production runs.

Key advantages at a glance

• Ultra-low run-out: 10 microns of run-out to minimize tool deflection and deliver superior surface finish and dimensional tolerance in milling, drilling, and light turning.
• ER50 compatibility: Specifically designed to pair with standard ER50 collet chucks, ensuring a tight, repeatable interface for a wide range of tools and diameters.
• Precision-built for general-purpose machining: Ideal for holding round stock with confidence, whether you’re machining aluminum, steel, or other common metals.
• Durable, repeatable performance: Precision-ground steel construction stands up to frequent clamping cycles, delivering consistent grip and longevity in busy shop environments.
• Consistent results across uses: From quick setup jobs to longer run production, this standard precision collet maintains rigidity and repeatability for dependable results.

Practical tips for best results

• Keep the collet bore and tool shank clean and free of debris to preserve the 10 µm run-out performance.
• Use the correct ER50 chuck nut and follow a proper tightening sequence to maximize holding force without introducing play.
• Pair with appropriate cutting parameters and tool geometry to fully leverage the collet’s concentric accuracy for high-precision finishes.

Whether you’re setting up a delicate engraving pass, precision milling, or routine drilling tasks, the Omega ER50 Collet Standard Precision is designed to deliver reliable clamping, repeatable accuracy, and long-lasting performance in a compact, robust package.
