About This Product
Wet Diamond Blades for Porcelain Tile
Alpha® Porcellana Wet Diamond Blades are professional cutting blades formulated for dense porcelain tile and slab. The specialized diamond grit and matrix balance efficient cutting speed with minimal chipping, helping produce cleaner finished edges and reduce wasted material.
Continuous Rim for Low-Chip Cuts
The continuous rim diamond blade design uses fine diamonds to maintain uninterrupted contact with the material and minimize edge chipping. The 8" and 10" models feature a 3/8" (10mm) tall diamond layer for extended cutting life during repeated tile saw use.
Porcelain, Ceramic and Stone Compatibility
Porcellana is a hybrid wet blade recommended for porcelain, ceramic tile, granite, marble, engineered stone, and travertine. This broad material compatibility gives tile installers one wet cutting blade series for porcelain and many other common tile and stone products.
Handheld Cutter and Tile Saw Sizes
Five blade sizes are available. The 4-3/8" and 5" models fit compatible stone cutters and angle grinders configured for wet cutting, providing a portable jobsite option without a full-size tile saw. The 7", 8", and 10" models have 5/8" arbors and are designed for compatible tile saws.
Continuous Water Flow and Blade Maintenance
Porcellana blades are for wet use only and require continuous water flow to prevent excessive heat buildup and blade damage. Water also reduces dust and supports cutting performance and blade life. Routine re-dressing may not be necessary under proper cutting conditions, but a blade that slows because of glazing should be re-dressed with a suitable dressing stone or soft abrasive material.
