5/10 pcs 40mm diamond cutting wheel with 6mm shaft for grinding, carving, cutting porcelain tiles, granite, marble, and ceramic. Achieves fast and precise cuts. The diamond grinding particles reduce vibrations and ensure straighter, faster cutting. Sharp edge resists clogging and provides excellent wear resistance. High cutting speed allows ceramic tiles to be cut within one minute, saving time and effort. Strong and durable stone cutting blades made of high-quality diamond steel using hot press sintering technology for extended lifespan. New soldering process prevents deformation and cracking, enhancing safety during use. Easy to use design suitable for both dry and wet applications on multiple materials. Removable and flexible for convenient operation with lower costs and simpler handling. Widely applicable for precision cutting, slicing, and shaping of granite, marble, and concrete. Also suitable for cutting wood, plastic, and metal. Two different specifications available: sharp type and wear-resistant type. Sharp cutting discs provide smoother performance while wear-resistant discs offer longer durability. Easy to use and maintain, providing a cost-effective solution for stone cutting.
