Omega Products DV40 Shrink Fit Chuck - G2.5 - 25,000 RPM - 3mm - 160mm Long

The Omega DV40 Shrink Fit Chuck is a precision tool holder designed for demanding high-speed milling and drilling workflows. It’s built for engineers, machinists, and dedicated hobbyists who need reliable tool retention at speed. With a maximum operating speed of 25,000 RPM and a G2.5 balance rating, it delivers stable, accurate performance even under tough cutting conditions.

The shrink-fit design uses heat-induced expansion and subsequent cooling to securely grip the tool, eliminating the need for additional clamping. Its 160 mm length keeps setups compact while delivering a rigid interface for precise, repeatable results.

• High-speed stability at 25,000 RPM: The G2.5 balance rating minimizes vibration, helping you maintain tight tolerances and a clean finish during demanding cuts.
• Shrink-fit precision grip: The heat-expanded/contracted interface provides a tight, repeatable hold on the tool, dramatically reducing runout for higher accuracy.
• Clamping-free tool retention: No external clamps or drawbars are required—the shrink-fit action securely holds the tool, simplifying setups and saving cycle time.

This combination of speed, stability, and secure retention means you can rely on consistent results across shifts and jobs. The DV40 shrink-fit chuck helps streamline workflows, reduces downtime from tool changes, and supports higher-quality finishes in a wide range of materials and applications.
