These pads give a factory finish on engineered stone in only 3 steps. They will never bleed color into the stone and are less likely to burn the material the way that resin pads can. As with our other 3-step pads, these pads utilize new diamond technology to produce desired results in half the time of regular 7-step pads. These pads must be run wet to prevent the resin in the stone from burning. Recommended RPM is 3000.
