40mm diamond blade with 6mm shank cutting disc wheel for engraving and cutting tiles, granite, marble, and ceramic materials. Designed for precise, fast, and accurate cuts. The diamond grinding grains reduce vibration and ensure straighter, quicker cutting performance. Sharp edge resists clogging and provides excellent wear resistance. Achieve rapid cutting speedceramic tiles can be cut within one minutesaving time and effort. Strong and durable stone cutting blades are made from high-quality diamond steel using hot-pressed sintering technology for extended lifespan. Advanced soldering process prevents deformation and cracking, offering safer operation. Suitable for both dry and wet applications across multiple materials. Removable and flexible design allows for easy use, lower costs, and simple handling. Blade diameter: 40mm, thickness: 0.2mm. Ideal for precision cutting, trimming, and shaping of granite, marble, and concrete. Also suitable for cutting wood, plastic, and metal. Two available types: sharp type for smooth cutting and wear-resistant type for longer durability. Easy to use and maintain, providing a cost-effective solution for stone cutting tasks. Package includes: 5 or 10 pieces of wear-resistant or sharp type saw blades, or 10 pieces (5 wear-resistant + 5 sharp type). Note: 1.
