Omega Products DV40 Shrink Fit Chuck With Front Face Coolant - G2.5 - 25,000RPM - 16mm Clamping Diameter - 120mm Gauge Length

The Omega DV40 Shrink Fit Chuck with Front Face Coolant is a high-precision toolholding solution designed for DIN 69871 spindles. It delivers strong clamping force and rigidity for demanding milling tasks, while front-face coolant channels help keep tools cooler and cutting zones efficient. This makes it a reliable choice for engineers, machinists, and workshops seeking repeatable accuracy at speed.

With a 4.5-degree taper, 16mm clamping diameter, and a 120mm gauge length, the chuck is balanced to G2.5 at 25,000 RPM, delivering stable performance and minimal vibration during high-speed cuts. Integrated front coolant channels enhance heat dissipation and cutting efficiency, helping tools last longer under heavy use.

• Integrated Front Face Coolant: Front coolant channels direct coolant precisely to the cutting zone, improving heat management, extending tool life, and maintaining surface finish during high-speed milling.
• DIN 69871 Form AD/B Compatibility: Designed to mate securely with standard spindles, providing consistent grip and repeatable accuracy with every tool change.
• High‑Speed Stability and Balance: Balanced to G2.5 at 25,000 RPM with a 4.5° shrink taper, reducing vibration for cleaner finishes and reliable performance under demanding cutting conditions.

This DV40 chuck helps you streamline setups, reduce tool wear, and achieve dependable results across a range of materials and applications. Its combination of front-face coolant, DIN-standard compatibility, and precision balance makes it a practical, long-lasting choice for professional shops and serious hobbyists alike.
