The Omega DV40 ER Collet Chuck is a precision toolholder designed for DV40 spindle systems, using an ER25 collet to securely grip cutting tools. It offers a wide speed range from 15,000 to 25,000 RPM, enabling drilling, milling, and finishing tasks with a single, reliable chuck. Built to DIN69871 standards, it ensures seamless compatibility with DV40 spindles and repeatable tool changes. The chuck is available with two precision balance ratings, G2.5 and G6.3, so you can select the level of accuracy that matches your machining needs. Its 160 mm gauge length provides extended reach and added rigidity for demanding operations, while the ER collet system delivers excellent gripping force and concentricity to keep tools centered at high speeds.

• Wide speed range for versatile machining: Handles 15,000–25,000 RPM to cover a broad set of drilling, milling, and finishing tasks without swapping chucks.
• DIN69871 DV40 compatibility: Ensures quick, reliable mounting to DV40 spindles with repeatable tool changes and consistent performance.
• ER25 gripping performance with extended reach: Provides strong, concentric tool clamping and the 160 mm gauge length adds stability and reach for demanding cuts at high speeds.

This chuck is built to support efficient workflows, delivering reliable tool retention, smooth operation at high RPMs, and consistent results across a range of applications. Choose the balance rating that fits your tolerance needs and experience improved rigidity, reduced runout, and longer tool life in daily machining tasks.
