Wet polisher for stone. Water is fed through three holes into every channel of the pad, so the pad runs cool instead of clogging with dust. Speed is set on a dial from 2,000 to 4,000 rpm and held under load by constant speed control, with soft start and overload protection. Takes 100 to 125 mm hook and loop pads. 900 W, double insulated, 2.3 kg without the cable, 5.0 m cord.
