BBX2 is a very aggressive resin tool for the first grinding step. It can be used with advantage as the first step on marble, terrazzo and limestone. BBX2 is a continuation of the BB series, now with a unique technology enabling the use of coarse diamonds in a composite diamond tool. BBX2 is strongly recommended together with our Diamond Xpress series. With this combination it is now possible to completely dry-process marble, terrazzo and limestone, without having to use water.
