The Omega DV40 ER16 Mini Collet Chuck is a compact, high-speed toolholder built for DV40 spindle systems. It operates from 15,000 to 25,000 RPM with ER16 tooling, delivering secure tool gripping and precise concentricity for milling, drilling, and finishing tasks.

Designed for tight spaces, this 70mm gauge-length chuck fits where room is at a premium and supports DIN69871 compatibility for easy integration into existing setups. It uses an ER collet system to maintain strong, repeatable grip on tools at speed, reducing runout and improving surface finish.

• ER16 gripping with tight concentricity: The ER collet system provides uniform clamping force and high concentricity, ensuring secure toolholding at speeds up to 25,000 RPM and consistent results.
• Compact DV40 mini design for tight workspaces: With a 70mm gauge length, the chuck fits into confined tool paths, improving accessibility and reducing setup time without sacrificing rigidity.
• DIN69871 compatibility with selectable balance: Ensures seamless integration with standard DV40 spindles and offers balance options G2.5 or G6.3 for stable, low-vibration operation and longer tool life.

This combination of precision gripping, compact form, and tailored balancing delivers faster, more repeatable setups, smoother runs at high RPM, and improved finish quality. It helps reduce downtime from tool changes, supports consistent performance across jobs, and makes high-speed machining in tight spaces more productive for workshops and production lines alike.
