The RUBI CPA diamond blade range is especially recommended for cutting hard materials such as granite, rustic tiles, klinker, refractories, slate, etc. Being a continuous rim blade, the CPA blade offers the highest quality finish. The CPA diamond blade by RUBI is ideal for cutting and mitring joints in stoneware tiles, porcelain tiles, extruded stoneware and other wall covering materials that are extremely hard and with thicknesses of less than 25 mm. The RUBI CPA diamond blade combines, in its diamond rim, different metals and a very high-quality diamond grain. This allows us to offer a wet cutting diamond blade, with a high degree of satisfaction among professional ceramic tile fixers around the world. By means of laser welding, we have made the joint between the diamond rim and the steel core of the RUBI CONTINUOUS - CPA blade a guarantee of quality and safety for the user. Within its range of diamond blades, RUBI offers professionals two blade classes: PRO and SUPERPRO. The PRO blades offer the professional user the best price-performance ratio.
