The Omega DV40 ER Collet Chuck ER20 is a precision toolholding solution designed for DV40 spindle systems. It accepts ER20 tooling, delivers secure grip and high concentricity at speeds from 15,000 to 25,000 RPM, and features a 160 mm gauge length with a Form AD interface for reliable DIN69871 mounting.

Built to the DIN69871 standard, this chuck is available with two precision balance ratings—G2.5 and G6.3—so you can choose the level of accuracy that matches your application. The ER collet system provides strong gripping force and exceptional concentricity, keeping tools centered during high-speed machining for consistent, high-quality results.

• DV40/DIN69871 compatibility: Seamless mounting to DV40 spindles that conform to DIN69871, enabling quick, repeatable tool seating and reliable alignment.
• Two precision balance options: G2.5 and G6.3: Choose the balance grade that suits your tolerance needs, reducing vibration, improving surface finish, and extending tool life.
• ER20 collet system with strong grip and concentricity: The ER20 grip holds tools securely with minimal runout, delivering accurate drilling and milling results even at high speeds.

With the Omega DV40 ER Collet Chuck ER20, you gain a reliable, versatile toolholding solution that fits directly into your DV40 setup. Expect faster tool changes, reduced runout, and more consistent results across milling and drilling operations. The combination of DIN69871 compatibility, selectable balance accuracy, and a robust ER collet translates into smoother cycles, longer tool life, and improved overall productivity on a busy shop floor.
