The DV50 Hydraulic Expansion Chuck - HC20S (Fig.1) is a DIN69871‑compliant toolholding solution designed for a wide range of CNC machining centers and tool holders. With a maximum speed of 25,000 RPM, it delivers quick, precise clamping that remains secure at high speeds and minimizes tool runout for stable cutting and better surface finish. The hydraulic expansion mechanism is engineered to expand evenly, providing a uniform grip that dampens vibration and supports consistent, repeatable results.

• Hydraulic expansion for uniform tool grip: Even hydraulic pressure ensures consistent gripping force across the tool shank, reducing runout and enhancing stability during high-speed machining.
• DIN69871 compatibility for versatile use: Designed to fit a broad range of machining centers and tool holders, simplifying tool changes and minimizing compatibility concerns.
• High-speed performance with vibration damping: Capable of up to 25,000 RPM with effective vibration damping, delivering improved surface finish, dimensional accuracy, and extended tool life.

This chuck helps you work more efficiently by enabling rapid, repeatable tool clamping while maintaining rigidity at demanding speeds. The combination of uniform expansion, vibration damping, and DIN69871 compatibility translates to tighter tolerances, smoother finishes, and longer tool life, making it a dependable choice for production environments and precision applications.
