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 grains reduce vibration and ensure straighter, quicker cutting performance. The blade is sharp, does not sink in during use, and is resistant to 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, offering extended service life. Advanced soldering process ensures no deformation or cracking, providing safer operation. Suitable for both dry and wet applications across multiple materials. The blade is removable and flexible for easy use, with lower costs and simpler operation. The blade has a diameter of 40mm and a thickness of 0.2mm. It can precisely cut, slice, and shape granite, marble, and concrete. It is also suitable for cutting wood, plastic, and metal. Two different specifications available: one is a sharp type for smooth cutting, and the other is a wear-resistant type for longer durability. The blade is easy to use and maintain, offering a cost-effective solution for stone cutting. Package includes: 5/10 pieces of wear-resistant or sharp type cutting blades, or 10 pieces (5pcs wear-resistant + 5pcs sharp type). Note: 1.
