Omega DV40 ER Collet Chuck, ER25, is a DIN69871-compliant toolholder designed for DV40 spindle systems. With a 70mm gauge length and Form AD mounting, it delivers secure, repeatable tool seating for milling, drilling, and precision finishing across a wide range of materials.

It supports a broad speed range of 15,000 to 25,000 RPM, enabling flexible use across jobs from heavy milling to fine drilling. The ER25 collet system provides strong gripping force and excellent concentricity, keeping tools centered for consistent results. It is available in two precision balance ratings, G2.5 and G6.3, so you can choose the level of accuracy that best fits your machining needs.

• Broad 15,000–25,000 RPM range: Provides versatility across drilling, milling, and finishing tasks, maintaining stable grip and consistent tool engagement at high speeds.
• DIN69871 compatibility with DV40 spindle (Form AD): Ensures quick tool changes and reliable seating with standard DV40 machines, reducing downtime and setup variability.
• ER25 gripping power and concentricity: Delivers strong clamping force and true concentric engagement for tighter runout control and improved surface finish even at high speeds.

This combination of standard interface, precise gripping, and flexible speed makes the Omega DV40 ER25 chuck a reliable workhorse for engineers, machinists, and maintenance technicians alike. It helps streamline tool changes, improve finish quality, and maintain consistent performance across diverse jobs, delivering dependable results in both production environments and shop floors.
