Description

The Omega ER25 Collet Ultra Precision is a high-precision clamping solution designed to hold round shank tools securely in an ER25 collet chuck. It’s ideal for engineers, machinists, and hobbyists who demand consistent accuracy in milling, drilling, and precision machining workflows.

With an demonstrated 5 micron run-out, this collet delivers near-perfect concentricity to minimize tool deflection. That tighter run-out translates into tighter part tolerances, smoother surface finishes, and more repeatable results across jobs—especially important for small-diameter tools and intricate features.

  • 5 Micron Run-Out Precision: Delivers exceptionally tight concentricity to improve accuracy, finish, and repeatable results across multiple parts.
  • ER25 Collet Chuck Compatibility: Designed to drop into standard ER25 chucks for easy integration with existing tooling setups and reliable clamping performance.
  • Secure Round-Shank Tool Clamping: Holds round-shank tools firmly during high-speed machining, reducing wobble and vibration for consistent, dependable cuts.

This ultra-precision collet helps you tighten tolerances, achieve cleaner finishes, and maintain steady workflow without resorting to alternatives. By aligning closely with standard ER25 chucks and delivering repeatable clamping quality, it supports confident planning, faster setups, and more predictable machining results across a wide range of applications.
