Omega Products DV40 Shrink Fit Chuck With Front Face Coolant - G2.5 - 25,000RPM - 20mm Clamping Diameter - 80mm Gauge Length

Omega DV40 Shrink Fit Chuck with Front Face Coolant is a precision toolholder designed for high-speed milling and drilling where secure tool retention and heat management are critical. Built to the DIN 69871 standard (Form AD/B), this chuck delivers reliable seating, repeatable performance, and compatibility with a wide range of cutting tools.

Engineered for 25,000 RPM operation, the DV40 is balanced to G2.5 and uses a 4.5-degree taper for maximum rigidity. With a 20 mm clamping diameter and an 80 mm gauge length, it provides broad tool compatibility while maintaining a compact, stable profile for demanding cutting conditions.

• Front Face Coolant Channels for Efficient Cooling: Direct coolant flow to the cutting zone improves heat dissipation, reduces thermal distortion, and supports higher feed rates for cleaner finishes and longer tool life.
• DIN 69871 Form AD/B Compatibility for Universal Fit: Designed to work with standard tooling systems, enabling quick changes, consistent clamping force, and reliable performance across a broad tool range.
• High-Speed Stability: G2.5 Balanced at 25,000 RPM: The 4.5° shrink taper, balanced to G2.5, delivers minimal runout and strong grip at high speeds, with 20 mm tooling and 80 mm gauge length enhancing rigidity and versatility.

This DV40 chuck helps you streamline setups, keep tools cooler under intense cutting, and maintain precise, repeatable results across milling and drilling tasks. With robust heat management and proven DIN-standard interoperability, it’s a dependable choice for shops aiming to boost productivity and part quality.
