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 vibration and ensure straighter, quicker cutting performance. The blade is sharp, does not sink in during use, and is wear-resistant. 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 service life. Advanced soldering process prevents deformation and cracking, providing safer operation. Suitable for both dry and wet applications across multiple materials. The blade is removable and flexible for easy use, offering lower costs and simplified operation. With a diameter of 40mm and thickness of 0.2mm, this blade is ideal for precision cutting, slicing, and shaping of granite, marble, and concrete. It can also be used for cutting wood, plastic, and metal. Two different types are available: sharp type for smoother cutting and wear-resistant type for longer durability. Easy to use and maintain, providing a cost-effective solution for stone cutting tasks. Package includes: 5/10 pcs wear-resistant or sharp type blades, or 10 pcs blades (5 pcs wear-resistant + 5 pcs sharp type). Note: 1. Due to differences in monitor displays and lighting effects, the actual item color may vary slightly from the images shown. 2. Please allow 1-3 cm variation due to manual measurement.
