The Omega DV40 Shrink Fit Chuck is a precision toolholding solution built for high-speed milling and demanding machining tasks. Designed for 20 mm shank tooling, its shrink-fit design provides a tight, repeatable grip that minimizes tool runout and enhances cutting accuracy at speeds up to 25,000 RPM.

With a compact 200 mm length, the DV40 delivers a rigid interface that supports extended-tooling setups and stable performance across tough operations.

• Shrink-fit grip for precise engagement: Heat-induced expansion and cooling securely hold the tool inside the chuck, eliminating the need for additional clamping and reducing runout for reliable, repeatable accuracy.
• High-speed capability up to 25,000 RPM: Designed to maintain stability and precision during demanding milling tasks, enabling efficient cutting at elevated speeds.
• G2.5-balanced design for smooth operation: The balanced construction minimizes vibration at speed, helping achieve cleaner finishes and consistent results across complex molds and pockets.

Together, these features help you lock in tight tolerances, finish parts with confidence, and keep production moving with fewer reworks or adjustments.
