UltraMax Mini

UltraMax Mini Ultrasonic Polishing System

Suitable for use with platinum, gold, silver, and other soft jewelry metals, the UltraMax Mini Ultrasonic Polishing System is designed to enable precision finishing in the smallest areas. Harnessing high-frequency, low-amplitude ultrasonic technology to leave a bright, burnished surface, the system comes with a mirror-like finish carbide burnishing tip that glides across metal surfaces. The ergonomically designed handpiece operates in a continuous mode with a constant, almost imperceptible impact governed by the variable rheostat dial.
