The Omega DV40 Shrink Fit Chuck is a precision tool holder designed to deliver dependable, high-speed performance for CNC milling and drilling. Built for engineers, technicians, and hobbyists alike, it enables tight tool retention and accurate results at speeds up to 25,000 RPM, with a G2.5 balance rating for smooth operation.

Using heat-induced shrink-fit technology, this chuck securely grips 4 mm shank tools, eliminating the need for external clamps. When heated, the chuck expands to accept the tool; as it cools, it clamps firmly around the shank, delivering minimal runout and repeatable accuracy in demanding operations. Its 160 mm length is designed to fit common spindle setups and provide solid reach in typical configurations.

• Tight, repeatable shrink-fit grip: securely holds 4 mm shanks with minimal runout, delivering consistent tolerances and cleaner finishes.
• High-speed stability with G2.5 balance: engineered balance reduces vibration at up to 25,000 RPM for reliable precision in demanding operations.
• Clamping-free setup for fast changeovers: shrink-fit retention eliminates external clamps, simplifying alignment and speeding up tool changes while preserving accuracy.

This combination of secure retention, high-speed stability, and clamp-free operation helps you reduce setup time, maintain tighter tolerances, and achieve smoother surface finishes across milling and drilling tasks. With the DV40, you gain dependable performance in demanding workloads, longer tool life due to reduced runout, and confidence that your tooling stays precisely where it should—even when pushing toward higher speeds.
