The Metabo Wet Polisher is perfect for granite, marble and other high-quality types of rock. A thumbwheel allows the ability to work with materials requiring customized speeds, which remain constant under load. For safe and low fatigue gilding, an ergonomic housing cap has been installed, as well as overload protection prevents overheating. This allows for a soft and smooth start-up, which auto-stop carbon brushes protect the motor. Equipped with restart protection, unintentional startup after power supply interruption is prevented.
