The Omega DV40 Shrink Fit Chuck is a high-precision toolholding solution designed for CNC mills and turning centers. It clamps 4 mm tool shanks with a shrink-fit method, delivering fast tool changes and a secure grip at speeds up to 25,000 RPM. Ideal for engineers, machinists, tradespeople, and hobbyists who require consistent accuracy in high-speed machining.

With a G2.5 balance rating, it stays stable under demanding cutting conditions, helping you achieve tighter tolerances and smoother finishes without extra clamping hardware.

• Tight, runout-minimizing shrink-fit grip: The shrink-fit design uses controlled heat expansion and cooling to secure the 4 mm tool shank, reducing runout for repeatable accuracy in every operation.
• High-speed stability up to 25,000 RPM: G2.5 balance rating and precision construction minimize vibration, delivering clean cuts and reliable performance during demanding machining.
• Long, rigid 120 mm length for versatility: The extended body provides stiffness for deep pocketing with 4 mm tools, while maintaining a secure, clamp-free hold that simplifies setup.

When you use the DV40 shrink-fit chuck, you gain consistent tool engagement, reduced downtime from tool changes, and improved surface finish thanks to lower runout and stable high-speed performance. The reliable clamping method helps you maintain tight tolerances across jobs, boosting productivity and confidence in every cut.
