The Omega DV40 ER Collet Chuck (ER20) is a high-speed toolholding solution designed for DV40 spindle systems. It uses the DIN69871 mounting standard to ensure quick, reliable integration with compatible machines, and it supports a broad speed range from 15,000 to 25,000 RPM to cover a wide range of milling and drilling tasks.

Featuring a 100 mm gauge length and Form AD interface, this chuck delivers consistent tool positioning and repeatable results. It is offered with two precision balance options—G2.5 and G6.3—so you can select the level of accuracy that best fits your machining requirements.

• Wide speed range (15,000–25,000 RPM): Provides ready-to-use versatility for a broad spectrum of milling tasks, helping you handle different materials and tooling needs without swapping chucks.
• DIN69871 compatibility with DV40 spindles: Ensures a straightforward, secure mount on standard DV40 machines, promoting consistent alignment and repeatable results across jobs.
• ER collet system with strong grip and concentricity: Delivers secure tool retention at high speeds and minimizes runout, supporting precise cutting performance.

Together, these features translate to reliable, repeatable results across multiple jobs: fast, secure tool holding with standard DIN69871 mounting, precise gripping and concentricity at speeds up to 25,000 RPM, and the flexibility to choose the right balance grade (G2.5 or G6.3) for your tolerance and finish requirements. The Omega DV40 ER Collet Chuck is a dependable choice for engineers, machinists, and hobbyists who need consistent performance and smooth workflow in high-speed applications.
