Our CNC ER Collets are engineered to deliver exceptional concentricity, minimizing tool runout and improving machining precision. This results in smoother cutting, higher-quality surface finishes and extended tool life.
Available in various sizes including ER11, ER16, ER20, ER25, ER32, ER40, and ER50, these collets are compatible with most standard ER collet chucks worldwide
Product Advantages
1. Superior Clamping Accuracy
Precision-ground CNC ER Collets provide excellent concentricity and low runout, ensuring higher machining accuracy, improved surface finish and consistent production quality.
2. Strong and Uniform Clamping Force
The 360° clamping design distributes gripping force evenly around the cutting tool, reducing tool slippage and maintaining stable performance during heavy-duty machining.
3. Extended Tool Life
Accurate tool positioning and reduced vibration minimize cutting edge wear, helping to extend the service life of drills, end mills, reamers and other cutting tools.
4. Improved Machining Efficiency
Quick tool changes and reliable clamping reduce machine downtime, increase productivity and support high-volume CNC manufacturing.
5. Excellent Compatibility
Compatible with all standard DIN 6499 ER collet chucks, including ER11, ER16, ER20, ER25, ER32, ER40 and ER50 systems, making integration into existing CNC equipment simple and cost-effective.
6. High-Speed Machining Performance
Designed for high-speed CNC applications, CNC ER Collets offer excellent balance and stability, minimizing vibration and ensuring reliable machining at high spindle speeds.
7. Wide Tool Diameter Range
Available in both metric and inch sizes, CNC ER Collets accommodate a broad range of tool diameters, reducing inventory requirements and increasing machining flexibility.
8. Long Service Life
Manufactured from premium spring steel and heat-treated for enhanced hardness and elasticity, CNC ER Collets provide excellent wear resistance and long-term dimensional stability.
9. Versatile for Multiple Machining Operations
Suitable for milling, drilling, reaming, tapping and boring, CNC ER Collets offer a reliable solution for a wide range of metalworking applications.
10. Cost-Effective Tool Holding Solution
High durability, repeatable accuracy and reduced tool wear help lower tooling costs and improve the overall return on investment in CNC machining.
