Description

The Omega ER25 Collet Ultra Precision is a purpose-built toolholding accessory designed to securely grip round shank tools in an ER25 collet chuck. It is engineered to deliver consistently high-precision results in milling, drilling, and finishing work, helping you maintain tight tolerances with confidence.

With an exceptionally tight run-out specification of 5 microns, this collet set improves tool alignment and reduces vibration during cutting, contributing to smoother finishes and more accurate part features. It’s a reliable choice for shops and hobbyists that demand repeatable performance from their ER25 setups.

  • Ultra-Low Run-Out: 5 micron run-out enables highly accurate tool positioning, helping you achieve better tolerance control and surface finish across jobs.
  • Secure Round-Shank Clamping: Precise grip on tool shanks minimizes slipping and maintains consistent alignment through multiple tool changes.
  • Durable Construction: Hardened-steel design with tight tolerances delivers long life and reliable accuracy in demanding machining environments.

This collet set supports streamlined workflows by delivering repeatable, precise results with minimal setup fuss. Expect fewer reworks, quicker tool changes, and steady performance that keeps your projects on schedule and your finishes consistent, edge-to-edge.
