Description

Omega Products Dual Contact DCBT40 ER25 Collet Chuck is a precision tool holder designed for high-speed milling and demanding engineering environments. Built to work with standard ER25 collets, it provides secure, repeatable tool retention and consistent performance across a range of applications. Featuring Form AD and a 100mm gauge length, it’s optimized for stability in busy shop floors and tight machining setups.

With a dual contact design that combines face and taper engagement, this chuck locks tools firmly for improved concentricity and reduced runout at speeds up to 25,000 RPM. It is precision-balanced to G2.5, delivering smooth operation, longer tool life, and cleaner finishes even on demanding materials.

  • Dual contact stability: Face and taper engagement create a rigid grip on the tool shank, minimizing runout and delivering consistent, accurate results at high speeds.
  • Precision balance to G2.5 at 25,000 RPM: Optimized for smooth rotation, reduced vibration, and extended tool life during fast, productive milling and drilling cycles.
  • Form AD with standard nut clamping: Reliable, repeatable tool holding with common ER25 tooling, enabling quick setup and dependable retention in busy work environments.

This collet chuck translates into real-world benefits: tighter tolerances, faster cycle times, fewer rework passes, and a dependable performance across a variety of materials and applications. Its robust, precision-machined design helps keep your spindle productive, so you can focus on delivering high-quality finishes and efficient machining operations.
