Omega ER50 Collet Standard Precision is built for machinists who demand unwavering accuracy when clamping round stock in an ER50 collet chuck. With an exceptionally tight 10 micron run-out, this collet delivers dependable concentricity across a range of general purpose machining tasks—from precise milling to accurate drilling.

Why this ER50 collet stands out

• Ultra-low run-out: A measured 10 micron run-out minimizes deviation at the tool tip, helping you maintain tight tolerances on small-diameter features and fine finishes.
• Reliable round stock clamping: Specifically designed to grip round workpieces securely in standard ER50 collet chucks, reducing run-out over extended operations and improving repeatability.
• Durable, precision-made steel: Crafted for longevity in demanding shop environments, with smooth faces and accurate tolerances that resist wear and inconsistent grip.
• Easy integration into existing setups: Engineered to drop into your existing ER50 tooling ecosystem without the need for special adapters, making upgrades simple and straightforward.
• Versatile for multiple applications: Ideal for general machining needs—milling, light drilling, engraving, and finishing tasks where stable workholding matters most.

Use cases and practical tips

In a typical milling workflow, pair this ER50 collet with high-precision end mills or drills to keep diameter control tight and surface finishes consistent. For turning or rotary operations on centers, this collet helps maintain concentricity across passes, reducing eccentricity-induced chatter. To preserve accuracy over time, clean the collet seat and run-out surfaces before each setup and store the tool in a clean, dry environment to minimize corrosion and debris buildup.

The ER50 standard precision design is especially well-suited for shops that prioritize repeatable results and straightforward maintenance, allowing you to focus on part quality rather than toolholding quirks.
