The Omega DV40 Shrink Fit Chuck is a precision tool holder engineered for high-speed machining. With a maximum operating speed of 25,000 RPM and a G2.5 balance rating, it delivers stable, accurate performance in demanding milling and grinding tasks.

Shrink-fit technology uses heat-induced expansion and controlled cooling to securely hold 25 mm tooling, eliminating the need for external clamps. The chuck features a 100 mm long body for extended reach in tight or long-reach setups.

• Shrink‑fit retention for ultra-tight grip: Heat-induced expansion and cooling create a secure tool hold that minimizes runout and boosts accuracy during high-speed machining.
• High-speed stability with precise balance: Up to 25,000 RPM with a G2.5 balance rating delivers smooth, vibration-free operation that helps preserve finish quality and tool life at speed.
• Clamp-free setup for faster changeovers: Eliminates the need for external clamps, speeding tool changes and reducing setup downtime while maintaining reliable retention.

This chuck brings together secure retention, speed-ready balance, and straightforward setup to help you achieve repeatable, high-quality results. Expect improved cut stability, cleaner finishes, and less downtime between jobs—whether you’re in a professional shop or tackling ambitious DIY projects.
