The Omega DV40 ER Collet Chuck (Mini ER16) is a compact, high-speed toolholding solution designed for DV40 spindle systems. It's ideal for engineers, machinists, and hobbyists who work in tight spaces yet demand secure tool retention and repeatable accuracy.

With a speed range of 15,000 to 25,000 RPM and a 100 mm gauge length (Form AD), this mini chuck delivers versatile performance across a wide range of cutting tasks and tooling.

• Wide speed range and DIN69871 compatibility: Operates from 15,000 to 25,000 RPM and conforms to the DIN69871 standard, ensuring reliable fit with DV40 spindles and consistent performance across setups.
• Two precision balance options: G2.5 or G6.3: Choose the balance level that matches your tolerance and finish needs, reducing vibration and enhancing cutting quality for different materials and operations.
• ER16 gripping system in a compact DV40 mini design: Delivers strong gripping force and excellent concentricity for secure tool retention at high speeds, while the slim 100 mm gauge length enables easy access in cramped machines.

This combination of high-speed capability, precise balance choices, and a compact form delivers faster setups, improved concentricity, and reliable toolholding across demanding milling tasks. By integrating DIN69871 compatibility with your existing DV40 spindles, you can swap tools quickly with confidence, reduce runout, and achieve better surface finishes. Whether you’re upgrading a production line or tuning a hobby shop, this mini ER16 chuck helps you achieve repeatable results, lower downtime, and expanded machining versatility.
