The Omega DV40 ER Collet Chuck is a compact, high-speed toolholding solution designed for DV40 spindle systems. This mini ER11 chuck accepts standard ER collets and runs up to 25,000 RPM, making it ideal for precision milling, drilling, and finishing in confined spaces. Built to DIN69871 standards, it integrates smoothly with existing equipment and workflows.

Available in two precision balance grades (G2.5 and G6.3) to suit your tolerance and finish requirements, this chuck features a 70 mm gauge length and a Form AD/B back-end for easy mounting in tight setups.

• Wide high-speed range: Operates from 15,000 to 25,000 RPM to support a broad range of tools and materials, enabling faster cycles and consistent finishes.
• Secure grip with precise concentricity: ER collet system provides strong holding power and tight runout control, ensuring reliable tool performance at high speeds.
• Compact, DV40-ready design with tuned balance: 70 mm gauge length fits tight work envelopes while maintaining DIN69871 DV40 compatibility; pick balance grade G2.5 or G6.3 to match your accuracy needs.

Designed for reliability in demanding environments, this chuck delivers consistent clamping force, minimizing runout and improving surface finish. The compact DV40 form enables access to small pockets and crowded setups without compromising rigidity, while the dual balance options let you tailor performance to your machining goals—whether you prioritize tighter tolerances or longer tool life. Install, run, and trust your tooling with fast, repeatable cycles and minimal setup adjustments.
