40mm diamond cutting wheel with 6mm arbor for engraving and cutting porcelain tiles, granite, marble, ceramic. Designed for fast and precise cuts. Diamond grinding particles reduce vibrations and ensure straighter, quicker cutting. Sharp edge prevents sinking into material and resists wear. Achieves rapid cutting speed, capable of cutting ceramic tiles within 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. New soldering process ensures no deformation or cracking, providing safer operation. Suitable for both dry and wet applications across multiple materials. Removable and flexible design allows easy use with lower costs and simple operation. Blade diameter is 40mm with a thickness of 0.2mm. Ideal 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 for smoother cutting and wear-resistant type for longer durability. Easy to use and maintain, offering a cost-effective solution for stone cutting. Package includes: 5/10 pieces of wear-resistant or sharp type saw blades, or 10 pieces (5pcs wear-resistant + 5pcs sharp type). Note: Due to variations in monitor display and lighting, actual item color may slightly differ from images. Allow for a 1-3 cm measurement deviation due to manual measuring. (1 inch = 2.54 cm).
