The RUBI Scoring Wheel Plus 7/8" (22mm) EXTREME is a high-performance scoring wheel designed for professional tile cutters, specifically engineered for tough ceramic materials like porcelain, large-format tiles, and surfaces with rough or structured finishes. Made from tungsten carbide with a superficial titanium treatment, this scoring wheel offers enhanced durability and up to 300% longer life compared to standard scoring wheels. It features a patented steel shaft design that ensures maximum precision and minimal vibration during use, resulting in clean, consistent scoring lines. The 22mm (7/8") diameter improves surface contact and scoring depth, making it ideal for challenging materials resistant to standard wheels.
