Rubi SILVER Replacement Scoring Wheels — A Fresh Edge for Clean Breaks A manual cutter is only as good as its scoring wheel, and a worn or wrong-size wheel gives you shallow, wandering scores and ragged breaks. These Rubi SILVER replacement wheels put a sharp, correctly-angled edge back on your cutter. They're sintered tungsten carbide on a 10 mm shank, and each roller is rectified to a material-specific scoring angle — so the wheel is matched to the tile, not just close enough. They fit a wide range of Rubi manual cutters, including the TR-MAGNET, TS-MAX, SPEED-MAGNET, SPEED-N, FAST, STAR-MAX, STAR, POCKET, and PRACTIC. Match the diameter to your material: 6 mm for wall and glass tile, 8 mm for porcelain floor and wall tile, and 10 mm for porcelain floor tile and rustic, textured surfaces. The right wheel is the difference between a clean snap and a cracked tile. Why Tile Pros Choose It Material-matched angle: Each wheel rectified to a tile-specific scoring angle Tough carbide: Sintered tungsten carbide holds an edge under heavy use Wide compatibility: Fits many Rubi cutters on a 10 mm shank Size for the job: 6 mm glass/wall, 8 mm porcelain, 10 mm rustic/textured Cleaner breaks: A sharp, correct wheel scores deep and true Cheap fix, big difference: A worn wheel is the most overlooked cause of bad cuts Pro tip: Don't wait for a wheel to fail — if your breaks are getting ragged or you're scoring twice, swap it. Match the wheel size to the tile and keep the carriage clean so the new wheel tracks straight.
