Meet the Omega DV40 ER Collet Chuck ER25 — a precision toolholding solution built for DV40 spindle systems. It’s ideal for engineers, machinists, tradespeople, and hobbyists who value fast setup and reliable performance in milling and drilling at high speeds. Built to DIN69871 standards, it mates with standard DV40 spindles and accepts ER25 collets for broad tooling compatibility.

Available in two precision balance classes (G2.5 and G6.3), you can choose the level of accuracy that matches your project needs. The ER collet system delivers strong gripping force and tight concentricity, keeping tools centered and cut quality consistent even at high RPM. With a 100 mm gauge length, overhang is stable for predictable results and reduced vibration during demanding operations.

• Broad speed range for versatile machining: 15,000–25,000 RPM lets you switch between fast roughing and precise finishing without changing equipment.
• DIN69871 compatibility for quick, repeatable tool changes: Standardized interface ensures safe seating and fast setup with DV40 spindle systems.
• ER collet technology for secure grip and precision: High clamping force and excellent concentricity minimize runout and tool run issues at speed.

When you pair this chuck with your existing DV40 setup, you gain faster tool changes, tighter tolerances, and more stable cutting performance across a wide range of operations. The robust ER collet system reduces runout, so hole quality and finish are more dependable, while the 100 mm gauge length provides a solid, predictable overhang for lengthy cuts. Built to survive daily use in machine shops and production environments, this chuck delivers reliable performance you can trust job after job.
