Omega DV40 Shrink Fit Chuck with a 120 mm long body is a compact, high-precision toolholder designed for 3 mm tooling shanks. Built for demanding machining, it delivers stable performance at speeds up to 25,000 RPM with a G2.5 balance rating, providing a tight, concentric grip that preserves accuracy during heavy cuts.

• Shrink-fit precision for minimal runout: The heat-expanded grip tightens around the tool shank as it cools, delivering a consistently concentric hold that reduces runout and improves finish quality.
• High-speed stability with exact balance: Rated to 25,000 RPM and balanced to G2.5, ensuring smooth operation, reduced vibration, and longer tool life in demanding operations.
• Clamp-free retention for easy setup: No external clamps required—the shrink-fit mechanism secures the tool securely through controlled heating and cooling, simplifying changes and boosting uptime.

This chuck provides a reliable, quick-to-use solution that keeps tools centered, reduces setup complexity, and maintains consistent performance across high-speed machining tasks. With 3 mm tooling compatibility and a robust 120 mm form factor, it supports repeatable, efficient workflows and confident results at up to 25,000 RPM.
