The Omega DV40 Shrink Fit Chuck is a precision toolholding solution built for high-speed machining and demanding workloads. With a 12 mm shank and a generous 120 mm length, it delivers a stable, repeatable grip for cutting tools while operating up to 25,000 RPM. Its shrink-fit design secures tools tightly through a heat-and-cool cycle, eliminating the need for additional clamping and helping maintain tight tolerances in every pass.
Designed for a broad audience—from engineers and machinists to hobbyists—the DV40 combines reliability with ease of use, making fast, accurate tool changes a routine part of your workflow.

• Secure shrink-fit grip: Delivers a tight, repeatable hold on the tool, minimizing runout and enhancing cut accuracy across sessions.
• High-speed balance and stability: G2.5 balance rating minimizes vibration at up to 25,000 RPM for cleaner finishes and consistent performance.
• Easy mounting without extra clamps: Heat-induced expansion and controlled cooling lock the tool securely in place, reducing setup time and downtime.

With dependable stability and a straightforward mounting process, the DV40 Shrink Fit Chuck helps you achieve precise results, shorter setup times, and smoother workflows in busy workshops. Its robust construction and balanced design provide confident performance across everyday milling and demanding applications alike.
