Maximise precision and cooling efficiency with our DV40 Shrink Fit Chuck With Front Face Coolant. Engineered to the DIN 69871 standard, this chuck delivers superior clamping strength and rigidity for demanding high-speed milling. With integrated front coolant channels and a 4.5-degree taper, it keeps cutting temperatures under control while maintaining precise tool alignment.

Designed for engineers, machinists, and shop floors that run fast, accurate milling, the DV40 is balanced to G2.5 at 25,000 RPM, ensuring stable operation and minimal vibration. It features a 4mm clamping diameter and a 120mm gauge length for compact tooling setups that still offer robust retention across a wide range of tools.

• Front Face Coolant System: Integrated channels on the front face provide direct cooling to the tool interface, improving heat dissipation, extending tool life, and delivering consistent cutting performance on long, high-speed passes.
• DIN 69871 Form AD/B Compatibility: Built to standard toolholding interfaces for reliable fit, precise alignment, and seamless integration with existing machines and tooling setups, even at high speeds.
• High-Speed Balance and Strong Retention: 4.5° shrink-fit taper balanced to G2.5 at 25,000 RPM to minimize vibration and maximize tool life in fast milling, with a 4 mm clamping diameter and 120 mm gauge length for versatile, robust holding.

This combination of precise clamping, efficient cooling, and standardised compatibility helps you achieve repeatable results, reduce downtime, and maintain tight tolerances across high-speed operations. Upgrading to the DV40 means more productive cycles, cleaner finishes, and lasting reliability in a demanding shop environment.
