The Omega DV40 Shrink Fit Chuck is a high-speed toolholding solution designed for precise milling and drilling. Built for professionals, engineers, and serious hobbyists, it securely grips tools up to 8 mm in shank diameter with an 80 mm length, making it versatile across many setups. At speeds up to 25,000 RPM and with a G2.5 balance, it delivers stable, accurate performance in demanding machining tasks. The shrink-fit bore expands with heat to accept the tool and tightens as it cools, providing a tight, clamp-free grip that minimizes runout and simplifies tool changes.

• Secure shrink-fit toolholding: Heat-expanded bore accepts the tool and tightens as it cools, delivering a precise, repeatable grip with minimal runout and eliminating the need for external clamping hardware.
• High-speed stability with G2.5 balance: Optimized balance and a 25,000 RPM rating minimize vibration, improving cutting accuracy and surface finish while extending tool life.
• 8 mm shank compatibility and 80 mm length: Designed to fit 8 mm shank tools with an 80 mm overall length, offering broad tool compatibility and rigid performance in deeper pockets and demanding setups.

This chuck helps you work more efficiently by reducing setup time and clamping complexity while delivering tighter tolerances and more consistent finishes at high speeds. Its durable construction and precise machining provide reliable performance across multiple jobs, making it a dependable choice for CNC mills, lathes, and other high-speed machining centers.
