The CoolSpeed Mini 90-4 provides reliable high-pressure cooling within a 10–60 bar (145–870 PSI) range, ensuring stable performance in precision machining. The CM-CI-R016-016-4-A features a compact 16 mm shank that delivers accurate control for tight-tolerance operations while maintaining steady tool alignment. Its rigid build minimizes thermal distortion over long cycles, supporting consistent machining quality. Compatible with 3, 4, and 6 mm tool diameters and 1/8" and 3/16" coolant ports, it integrates smoothly into standard coolant systems. This design boosts cooling efficiency, tool longevity, and overall machining consistency.
