40mm diamond cutting wheel with 6mm arbor for engraving, cutting porcelain tiles, granite, marble, and ceramic. Designed for fast and precise cuts. The diamond grinding grains reduce vibration and ensure straighter, quicker cuts. Sharp edge resists clogging and provides excellent wear resistance. High cutting speed allows ceramic tiles to be cut in just one minute, saving time and effort. Strong and durable stone cutting blades made from high-quality diamond steel using hot press sintering technology for extended lifespan. Advanced soldering process prevents deformation and cracking, ensuring safer operation. Easy to use design suitable for both dry and wet applications on multiple materials. Removable and flexible for convenient use, offering lower costs and simpler operation. Wide application: 40mm diameter, 0.2mm thickness. Ideal for precision cutting, slicing, and shaping of granite, marble, and concrete. Also suitable for cutting wood, plastic, and metal. Two different specifications available: one sharp type for smoother cutting, and one wear-resistant type for longer durability. Easy to use and maintain, providing a cost-effective solution for stone cutting. Package includes: 5/10 pcs wear-resistant/sharp type cutting blades or 10 pcs cutting blades (5 pcs wear-resistant + 5 pcs sharp type). Note: 1.
