40mm diamond cutting wheel with 6mm arbor for engraving and cutting porcelain tiles, granite, marble, and ceramic materials. Designed for fast and precise cuts, the diamond grinding particles reduce vibration and ensure straighter, quicker cutting performance. The blade is sharp, does not clog, and resists wear. Achieve rapid cutting speed—ceramic tiles can be cut within one minute—saving time and effort. Strong and durable stone cutting blades are made from high-quality diamond steel using hot press sintering technology, ensuring extended lifespan. Features a new soldering process that prevents deformation and cracking, providing safer operation. Easy to use design suitable for both dry and wet applications across multiple materials. Removable and flexible for convenient use, offering lower costs and simpler operation. Wide application: The blade has a 40mm diameter and 0.2mm thickness, suitable for precision cutting, slicing, and shaping of granite, marble, and concrete. Also effective for cutting wood, plastic, and metal. Two different specifications available: one is sharp type for smoother cutting, the other is wear-resistant type for longer durability. The blade is easy to use and maintain, providing a cost-effective solution for stone cutting. Package includes: 5/10 pcs wear-resistant or sharp type cutting blades, or 10 pcs cutting blades (5 pcs wear-resistant + 5 pcs sharp type). Note: 1.
