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 eliminate the friction of the wheel itself with the axis of the wheel. This combination allows the behaviour 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).
