40mm diamond blade with 6mm shank cutting disc wheel for engraving and cutting tiles, granite, marble, and ceramic. Designed for fast and precise cuts, the diamond grinding grains reduce vibration and ensure straighter, quicker cutting. The blade is sharp, does not sink in, and is resistant to wear. Achieve high cutting speed, capable of cutting ceramic tiles within minutes, saving time and effort. Strong and durable stone cutting blades are made from high-quality diamond steel using hot press sintering technology, offering extended lifespan. Advanced soldering process ensures no deformation or cracking, providing safer operation. Suitable for both dry and wet applications on multiple materials. Easy to install and remove, allowing flexible use with lower costs and simple operation. The blade has a 40mm diameter and 0.2mm thickness, ideal for precision cutting, trimming, and shaping of granite, marble, and concrete. Also suitable for cutting wood, plastic, and metal. Two different specifications available: one is sharp type for smooth cutting, the other is wear-resistant type for longer durability. Easy to use and maintain, providing a cost-effective solution for cutting tasks. Package includes: 5/10 pcs wear-resistant or sharp type saw blades, or 10 pcs saw blades (5 pcs wear-resistant + 5 pcs sharp type). Note: 1.
