40mm diamond cutting wheel with 6mm arbor for engraving, cutting porcelain tiles, granite, marble, and ceramic materials. Designed for fast and precise cuts, the diamond grinding particles reduce vibrations and ensure straighter, quicker cutting performance. The blade is sharp, does not clog, and resists wear. Achieve rapid cutting speed, slicing through ceramic tiles in minutes, saving time and effort. Strong and durable stone cutting blades made from high-quality diamond steel using hot-pressed sintering technology for extended lifespan. Advanced 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 simplified handling. Blade diameter measures 40mm with a thickness of 0.2mm. Ideal for precision cutting, trimming, and shaping of granite, marble, and concrete. Also suitable for cutting wood, plastic, and metal materials. Two versions available: sharp type for smooth cutting and wear-resistant type for longer durability. Easy to use and maintain, offering a cost-effective solution for stone cutting tasks. Package includes: 5 or 10 pieces of wear-resistant or sharp type cutting blades, or 10 pieces (5 wear-resistant + 5 sharp type). Note: Due to variations in monitor displays and lighting conditions, actual item color may slightly differ from images. Allow for a 1-3 cm measurement deviation due to manual measurement.
