The Omega Products ER20 Collet Ultra Precision is a high-precision clamping solution designed for ER20 collet chucks. It securely grips round shank tools with exceptional concentricity, delivering ultra-stable machining and tighter tolerances thanks to a guaranteed 5 micron run-out.

- 5 Micron Run-Out for Tight Tolerances: Delivers exceptional concentricity, which translates to cleaner cuts, better surface finish, and fewer rework passes.
- Wide 3.5–4.5 mm Shank Range: Enables flexible tool selection with fewer collets, speeding up setups and reducing inventory complexity.
- Consistent Grip and Durable Fit: Precision manufacturing yields repeatable clamping force, minimizing tool slip and maintaining accuracy across jobs.
In practice, this ER20 collet helps you lock in toolpaths with confidence, streamline workflow, and achieve reliable results across batches. The combination of ultra-low run-out, broad shank compatibility, and repeatable grip makes it a dependable choice for engineers, technicians, and hobbyists seeking consistent performance without guesswork.
