For use in woodworking, plastic, and light alloy machines, the RC 73 series automatic tool-change spindles are designed to be cooled by compressed air. The solution provides more efficient cooling than fan systems, while also allowing for a shorter overall length of the spindle.

Available in both ISO and HSK clamping systems, the tool holders are retained by special springs and are released by a pneumatic actuator. Proximity sensors are incorporated to ensure maximum safety and control of the tool change.
