Description
The Omega ER20 Imperial Collet is a precision tool holder designed for imperial-sized cutting tools. Built for reliability in milling, drilling, and other precision operations, it ensures accurate tool alignment and a secure grip.
With a 3/8 inch capacity and a true 10 micron run-out, this collet minimizes deflection during high-speed cuts, helping you achieve consistent finishes and longer tool life. It works seamlessly with standard ER20 collet chucks, enabling quick tool changes while maintaining peak performance.
- 10 Micron Run-Out: Delivers exceptional concentricity for cleaner cuts, tighter tolerances, and reduced rework by keeping the cutting tool perfectly aligned with the spindle.
- Imperial Tooling Compatibility: Specifically designed for imperial-sized tools and ER20 chucks, providing a secure grip and straightforward changes for everyday machining tasks.
- Durable, Precision-Engineered Construction: Built to tight tolerances with precision-ground surfaces, resisting wear and maintaining concentricity over many cycles to minimize downtime.
This ER20 Imperial Collet helps you streamline setups, improve repeatability, and protect tool life. The combination of low run-out and robust construction translates to better surface finishes, fewer defects, and faster throughputs across a wide range of applications—from prototyping to production. Trustworthy materials and standard ER20 compatibility ensure you can rely on this collet for reliable performance in demanding workloads.
