The exclusive machining and grinding of the Rubi 7/8 in. scoring wheel allow them to offer exceptional quality in scoring of both porcelain tiles and glazed stoneware tiles. The Rubi 7/8 in. scoring wheel makes it possible to obtain cuts without chipping the enamel or deviations. In the case of the 7/8 in. scoring wheel, the professional has a tool that is particularly recommended for those cases where it is difficult to obtain an optimum cut, due to the extreme hardness of the material or its enamel. The roller in a tile cutter ensures perfect scoring in the enamel or top layer of the tile, so that later, in the breaking process, you can get a straight and clean cut. Material: Tungsten.
