Description
Omega ER25 Collet – Standard Precision with 10 Micron Run-Out (14mm - 13mm)
Unlock reliable, repeatable clamping for round stock with the Omega ER25 Collet. Designed for use in an ER25 collet chuck, this standard-precision collet delivers a true 10 micron run-out, helping you achieve cleaner cuts, tighter tolerances, and more consistent surface finishes in everyday machining tasks.
Why this matters:
- 10 µm run-out minimizes deflection and eccentricity during high-speed milling, drilling, or boring, so tool paths stay accurate and finishes stay smooth.
- ER25 compatibility ensures a secure, repeatable grip in common collet chuck systems, reducing vibration and improving tool life.
- Standard precision built for general purpose machining, it’s a dependable choice for shops and workshops that value consistent performance without unnecessary complexity.
- Focused on practicality—great for everyday projects that demand reliable holding power and precise alignment without specialized setups.
Ideal for hobbyists and professional machinists alike, this ER25 collet is a straightforward, effective solution for clamping round stock in a wide range of milling and drilling applications. Use it to tighten tolerances on small-diameter workpieces, reduce runout-related errors, and improve the overall quality of your machined parts.
Practical tips for best results:
- Ensure the ER25 collet chuck is clean and free of debris before installation to maintain the 10 µm run-out rating.
- Use appropriate torque when tightening to preserve concentricity and prevent collet deformation.
- Run a quick test on a scrap piece with a dial indicator to verify run-out aligns with expectations for your setup.
The included image showcases the ER25 collet from multiple perspectives to illustrate its robust, symmetrical design and precision-ground surfaces.
