Omega DV40 ER Collet Chuck ER40 is a high‑performance toolholding solution for DV40 spindle systems. It securely clamps ER40 cutting tools and supports high‑speed machining up to 25,000 RPM, delivering stable, repeatable results.

Built for engineers, machinists, and serious hobbyists, it complies with DIN69871 for quick, drop‑in integration with standard DV40 spindles. With an 80mm gauge length and a choice of balance ratings (G2.5 or G6.3), this chuck provides the right mix of rigidity and precision for your specific machining needs.

• Wide high‑speed range: 15,000–25,000 RPM enables flexible milling and drilling with consistent concentricity and finish across tools and materials.
• DIN69871 DV40 compatibility with 80mm gauge length: Quick, tool‑ready integration with standard DV40 spindles and a stable seating length to reduce setup time and vibration.
• Balanced ER40 grip for accuracy: Available in G2.5 and G6.3 balance grades, the ER collet system provides strong gripping force and tight runout control for precise tool paths at high speed.

This toolholding solution helps you improve workflow by enabling fast changeovers, reliable tool holding, and consistent performance at high RPM. The combination of DIN69871 compatibility, robust ER40 gripping, and selectable balance grades reduces setup time, minimizes runout, and extends tool life—delivering cleaner finishes and higher productivity across a range of milling and drilling tasks.
