The constant evolution of ceramic materials is a challenge for professionals installing ceramic tiles. With the arrival of porcelain stoneware, the hardness of the materials became the professional's greatest concern. Now, with the new production processes, and with the consolidation of porcelain as a material of greater use, as well as the growing presence of large formats or ceramic sheet, the main handicap is the difficulty in cutting ceramic tiles. This difficulty is the result of combining hardness, thickness, surface finish and possible internal stresses of the material itself. For the most difficult ceramic materials, RUBI makes available to the professional the range of EXTREME wheels. EXTREME wheels  are made of high quality tungsten carbide, with a special coating of titanium carbide. Thanks to this coating, RUBI EXTREME wheels and wheels suffer less wear during use. But in addition, the EXTREME wheels when mounted on a bearing completely eliminates the friction of the wheel itself with the axis of the wheel. This combination allows the behavior of the EXTREME scoring wheels to be far superior to the rest, offering a soft score and a life of 300%, compared to SILVER wheels in the same conditions of use. The range of EXTREME wheels  are specially designed and recommended for the scoring  of ceramic materials with rough and structured surface finishes (textures or reliefs). EXTREME wheels are compatible with the RUBI cutter ranges: TS-MAX, TR-MAGNET and SPEED-MAGNET in its 10 mm version and with the TZ and TX-MAX ranges in the 12 mm version. In addition, RUBI EXTREME rulina is compatible with the TQ, TP-T and TP-S manual cutters, as well as the SLIM CUTTER ceramic sheet manual cutting system of the SLAB SYSTEM product range.
