The 18 mm RUBI scoring wheel incorporates a wheel made of high wear resistance tungsten carbide. The exclusive machining and sharpening of the 18 mm RUBI scoring wheel allows it to offer an exceptional quality in scoring, both ceramic tiles of porcelain stoneware (type BIa), as well as glazed stoneware tiles or extruded stoneware. The incision of the 18 mm scoring wheel is clean and shallow, but thanks to its large diameter, the user can demand a greater incision in harder materials without risk of damaging the edge of the wheel. The 18 mm RUBI scoring wheel allows to obtain cuts in rough and difficult to cut tiles without chipping in the surface or deviations. The shaft of the RUBI 18 mm wheel (protected under patent) is a profile of rectified steel that offers the professional maximum precision for its exclusive design with triple grooves and a high resistance to wear. The triple fluted (protected under patent) shaft of the RUBI range guarantees to the professional fixer the best fixation of the rider in the manual cutter, as well as a greater precision during scratching. The tile installation professional will find the 18 mm scoring wheel, a good ally for the most demanding jobs. The GOLD version of the RUBI scoring wheel has a coating of titanium nitirde on the tungsten carbide. This special coating increases the resistance to wear of the scoring wheel, resulting in a higher performance of the tool. RUBI is committed to quality.
