Description
The Omega Products ER20 Imperial Collet is a precision tool designed to hold imperial-sized cutting tools with exceptional concentricity in milling, drilling, and other machining tasks. It’s a reliable choice for engineers, machinists, hobbyists, and shops that depend on repeatable accuracy.
Featuring a tight 10-micron run-out specification and ER20 compatibility, this collet delivers a secure grip on imperial tools, minimizing deflection and helping you achieve clean cuts and consistent finishes across passes.
- 10‑micron run-out precision: Ensures tight concentricity and minimal deflection during machining, translating to better tolerances, smoother finishes, and more predictable tool performance.
- ER20 compatibility for secure, repeatable grip: Designed to work with standard ER20 collet chucks to clamp imperial-sized tools reliably, enabling quick changes and consistent results across jobs.
- Durable, precision‑ground construction: Built to maintain tight tolerances under load, resist wear, and deliver long service life with reliable clamping for demanding milling and drilling tasks.
With this collet, you’ll experience faster, more predictable tool changes, reduced rework, and improved surface finish thanks to precise tool alignment. It integrates smoothly with standard ER20 chucks and is built to maintain accuracy through demanding workloads, giving you confidence in every job.
