The Omega DV40 Shrink Fit Chuck with Front Face Coolant is a high-precision toolholding solution designed for demanding milling applications. It uses a shrink-fit grip combined with integrated front-face coolant channels to hold cutting tools securely while delivering coolant directly to the cutting edge, helping maintain tight tolerances and consistent finishes. Built to DIN 69871 standards, this chuck delivers reliable clamping strength and rigidity essential for high-performance machining.

Ideal for machine shops, engineers, and hobbyists who push cutting data to the limit, the DV40 supports up to 25,000 RPM while maintaining stability and accuracy. Its compact 14 mm clamping diameter and 160 mm gauge length provide a rigid interface that minimizes tool runout and deflection, contributing to cleaner cuts and longer tool life.

• Front-face coolant channels for targeted cooling: Direct coolant delivery to the cutting zone reduces heat buildup, extends tool life, and helps maintain precise tolerances even at high speeds.
• DIN 69871 compatibility with AD/B form: Easy integration with standard spindles ensures reliable seating, repeatable accuracy, and quick tool changes across compatible machines.
• Optimized taper and high-speed balance: 4.5° shrink-fit taper balanced to G2.5 at 25,000 RPM for stable, vibration-free performance and repeatable, high-precision results.

The DV40 delivers a dependable, high-performance interface that enhances workflow and reduces downtime. By combining strong clamping with efficient cooling and precise balance, it enables faster cycle times, better surface finishes, and consistent results across a range of materials and geometries.
