40mm diamond blade with 6mm shank cutting disc wheel for engraving and cutting tiles, granite, marble, and ceramic. Designed for quick and precise cuts, the diamond grinding grains reduce vibrations and ensure straighter, faster cutting. The blade is sharp, does not sink in, and is resistant to wear. Achieve fast cutting speed, ideal for ceramic tiles, saving time and effort. Strong and durable stone cutting blades are made from high-quality diamond steel using hot press sintering technology, providing extended lifespan. Advanced soldering process ensures no deformation or cracking, offering safer operation. Suitable for both dry and wet applications on multiple materials. Easy to install and remove, allowing flexible use with lower costs and simpler operation. The blade has a 40mm diameter and 0.2mm thickness, suitable for precision cutting, trimming, and shaping of granite, marble, and concrete. Also effective for cutting wood, plastic, and metal. Two different specifications available: 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. Package includes: 5 or 10 pieces of wear-resistant or sharp type saw blades, or 10 pieces (5 wear-resistant + 5 sharp type). Note: Due to differences in monitor displays and lighting effects, actual item color may slightly vary from images. Allow for a 1-3 cm measurement deviation due to manual measurement. (1 inch = 2.54 cm).
