The Omega DV40 ER Collet Chuck ER25 is a high-speed toolholding solution designed for CNC milling and drilling on DV40 spindle systems. It accepts ER25 tooling and delivers reliable performance across a broad speed range from 15,000 to 25,000 RPM, making it suitable for a wide variety of materials and applications.

Manufactured to DIN69871 standards with a 120 mm gauge length, this chuck integrates smoothly with existing machines and ensures repeatable, accurate tool positioning. Its ER collet system delivers strong gripping force and excellent concentricity, keeping tools centered and reducing runout even at top speeds for cleaner finishes and longer tool life.

• Broad speed range (15,000–25,000 RPM): Enables a single chuck to cover roughing to finishing tasks across different materials, reducing tool changes and setup time for improved uptime.
• DIN69871 compatibility with DV40 spindle and 120 mm gauge length: Provides drop-in compatibility with existing machines, ensuring fast, repeatable setups and consistent positioning through standardized mounting and reach.
• ER25 collet system with selectable balance (G2.5 / G6.3) for secure grip and precision: Delivers high clamping force and tight concentricity, with a choice of balance grades to match machining tolerance needs and minimize runout at high RPM.

Designed for reliability and precision, the Omega DV40 ER Collet Chuck helps you minimize downtime, improve workflow, and achieve consistent, high-quality results across a wide range of applications. Its robust grip, balanced options, and DIN69871 compatibility create a dependable foundation for efficient, predictable machining performance.
