The Omega DV40 Shrink Fit Chuck is a precision toolholding solution designed for high-speed machining. It supports 12 mm tool shanks and is built to perform reliably up to 25,000 RPM, with a G2.5 balance rating that emphasizes stability and accuracy during demanding operations. The shrink-fit design creates a tight, concentric grip on the tool through heat-induced expansion and controlled cooling, eliminating the need for external clamps and reducing tool runout for better overall performance.

• Shrink-fit grip for secure, runout-minimized tool holding: Heat-driven expansion and precise cooling create a uniform, strong grip on 12 mm tools, delivering consistent accuracy without extra clamping.
• High-speed stability up to 25,000 RPM: Engineered for demanding machining, it maintains alignment and finish quality at top speeds, boosting productivity and reliability.
• G2.5 balanced design for smooth operation: Tight balance reduces vibration and chatter, extending tool life and improving surface finish over long cutting cycles.

This DV40 chuck combines fast setup, secure tool retention, and dependable performance in a compact 80 mm overall length. Its heat-and-cool gripping method provides repeatable, tool-holding accuracy across jobs, helping you streamline changeovers, minimize downtime, and achieve consistently strong results on every part.
