The Omega BT30 ER Collet Chuck – Mini Type – is a precision tool-holding solution built for BT30 spindle systems. Its compact, lightweight design reduces tool overhang and improves balance, helping deliver steadier cuts and smoother surface finishes across a range of milling and drilling applications.

With a 70mm gauge length and an ER collet interface, this chuck enables quick, reliable tool changes and secure clamping. It supports speeds up to 20,000 RPM and features a G2.5 precision rating to maintain tight concentricity and minimize runout during high-speed machining.

• Compact, Lightweight Construction: Reduces tool overhang and improves balance, boosting accuracy and surface finish on BT30 machines.
• Fast, Secure ER Collet Change: ER collet system allows quick tool changes with reliable gripping, cutting setup time and downtime in high-speed cycles.
• High-Precision, High-Speed Performance: G2.5 tolerance keeps runout tight while handling up to 20,000 RPM for demanding milling tasks, ensuring consistent, repeatable results.

Together, these features streamline your workflow by enabling fast changeovers, stable tool engagement, and dependable performance at speed. The combination of rigidity, precision, and efficient tool changes helps you achieve consistent part quality, shorter cycle times, and higher uptime on BT30 machining centers.
