The Omega DV40 Shrink Fit Chuck is a high-speed tool holder designed for 6 mm milling tools. With a maximum speed of 25,000 RPM and a G2.5 balance rating, it delivers stable, precise performance in demanding machining tasks.

Its shrink-fit design uses heat-induced expansion and subsequent cooling to grip the tool tightly, eliminating the need for external clamps and minimizing runout for improved accuracy and surface finish. Built with a 120 mm long body, it provides ample reach for deeper pockets while maintaining rigidity and balance during high-speed cuts.

• Shrink-fit precision grip: Delivers a tight, uniform hold on 6 mm tools through controlled heat expansion and cooling, minimizing runout and boosting accuracy across passes.
• High-speed stability: Handles up to 25,000 RPM with a G2.5 balance rating for smooth operation, reduced vibration, and longer tool life in tough materials.
• Clamping-free tool retention: Eliminates external collets and nuts, enabling faster tool changes and repeatable grip with less setup effort, so you can keep production running.

When you pair the DV40 shrink-fit chuck with your 6 mm tooling, you gain reliable, repeatable performance at high speeds. The heat-and-cool retention reduces runout, delivering cleaner finishes and tighter tolerances. The 120 mm length supports deeper pockets and stable cutting conditions, while the removal of traditional clamps cuts setup time and downtime. This combination helps you complete jobs faster with consistent results across shifts and operators.
