40mm diamond blade with 6mm shank cutting disc wheel for engraving and cutting tiles, granite, marble, and ceramic. The diamond grinding grains reduce vibrations and ensure straighter, faster cuts. Sharp and resistant to sinking in, it is wear-resistant and enables quick cutting—ceramic tiles can be cut within one minute, saving time and effort. Strong and durable, these stone cutting blades are made from high-quality diamond steel using hot press sintering technology for extended lifespan. Advanced soldering process prevents deformation and cracking, enhancing safety during use. Designed for both dry and wet applications on multiple materials, the blade is easy to install and remove, offering flexibility, lower costs, and simpler operation. With a 40mm diameter and 0.2mm thickness, it provides precise cutting, shaping, and trimming of granite, marble, concrete, wood, plastic, and metal. Available in two specifications: sharp type for smooth cutting and wear-resistant type for longer durability. Easy to use and maintain, it offers 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: Due to differences in monitor displays and lighting, actual item color may vary slightly from images. Allow for a 1-3 cm measurement deviation due to manual measurement. (1 inch = 2.54 cm).
