Omega DV40 Shrink Fit Chuck — G2.5 balanced and capable of speeds up to 25,000 RPM — delivers precise, repeatable tool retention without the need for external clamps. This makes it a reliable choice for high-demand milling, drilling, and finishing tasks where stability and accuracy matter.

Designed to hold 20mm tooling with an 80mm long form, the shrink-fit process uses heat-induced expansion and subsequent cooling to secure the tool firmly. The result is a tight, repeatable grip with minimal runout, simplifying setup and reducing the need for additional clamping components.

• Shrink-Fit Retention: Heat-induced expansion and controlled cooling create a secure, clamp-free grip that minimizes runout and simplifies setup, improving overall machining accuracy.
• High-Speed Stability: G2.5 balance rating paired with a 25,000 RPM capability delivers steady performance, helping maintain precision during demanding, fast-spindle operations.
• 20mm Tooling Compatibility & 80mm Length: Optimized for 20mm tooling with an 80mm long profile, providing reliable retention and consistent results across high-speed applications.

With this chuck, you gain faster changeovers, reduced downtime, and more consistent results across repeats. The shrink-fit retention minimizes vibration and runout, protecting tooling and delivering reliable performance in busy production environments. The combination of 25,000 RPM capability and precise balance helps improve cut quality and overall machining efficiency.
