The Omega DV40 Shrink Fit Chuck is a precision toolholding solution designed for high-speed CNC machining. Built to perform in demanding milling and turning applications, it delivers up to 25,000 RPM with a G2.5 balance rating for smooth, stable operation and reliable accuracy.

Its shrink-fit design uses controlled heat to expand the chuck and securely grip tool shanks, delivering tight concentricity and minimized runout. When cooled, the tool remains firmly seated without the need for external clamping hardware, enabling faster setups and more consistent results. This model features a 25 mm size and a 120 mm long form factor, offering compatibility with a wide range of tooling and spindle configurations.

• Shrink-fit retention for minimal runout: Heat-expanded clamping delivers a tight, repeatable grip around the tool shank, reducing runout and improving accuracy through every pass.
• High-speed stability at 25,000 RPM (G2.5 balanced): Precision balance minimizes vibration, enhances surface finish, and extends tool life during aggressive cuts.
• Clamp-free, reliable form factor: Eliminates external collars and clamps for quicker tool changes and dependable seating in standard spindle interfaces; the 25 mm size and 120 mm length contribute to robust rigidity.

This DV40 shrink-fit chuck helps streamline workflows, shorten setup times, and consistently achieve tighter tolerances. By reducing runout and vibration, it supports cleaner finishes, longer tool life, and less downtime—making it a dependable choice for professionals across engineering, manufacturing, and workshop environments.
