The Omega BT30 ER Collet Chuck, Mini Type (ER16) is a compact tool holder designed for BT30 spindle systems. Its small footprint and light weight help balance the spindle and reduce tool overhang, contributing to steadier cutting and a finer surface finish. With a 150 mm gauge length, it provides a stable reach for a wide range of jobs while keeping the setup lightweight.

Built for high-speed milling, this chuck supports speeds up to 20,000 RPM and uses the ER collet system for quick and easy tool changes—keeping your workflow efficient in demanding applications. The mini-type BT30 ER16 chuck is engineered for tight concentricity (G2.5), helping minimize runout and maximize cutting performance at the highest speeds.

• Compact, Lightweight Mini Design: Small footprint and reduced tool overhang improve balance, boosting machining accuracy and helping achieve a smoother surface finish.
• Fast ER Collet System for Easy Tool Changes: ER16 compatibility enables quick, repeatable tool changes, reducing downtime and keeping high-speed workflows moving.
• High-Speed Precision (20,000 RPM, G2.5): Designed for up to 20,000 RPM with a G2.5 tolerance to maintain tight concentricity and minimal runout for reliable, consistent cuts.

By combining compact design, fast tool changes, and high-speed precision, this BT30 ER16 mini chuck helps you streamline setups, shorten cycle times, and deliver repeatable results across a broad range of materials and milling operations. Expect cleaner finishes, longer tool life, and confidence in dependable performance from first cut to final pass.
