40mm diamond blade with 6mm shank cutting disc wheel for engraving and cutting tiles, granite, marble, and ceramic materials. Designed for quick and precise cuts, the diamond grinding grains reduce vibrations and ensure straighter, faster cutting performance. The blade is sharp, does not sink in during use, and is resistant to wear. Achieves fast 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, providing extended service life. Features an improved soldering process to prevent deformation and cracking, offering safer operation. Suitable for both dry and wet applications across multiple materials. Removable and flexible design allows for easy use, lower costs, and simplified handling. 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 materials. Available in two specifications: sharp type for smooth cutting and wear-resistant type for longer durability. Easy to use and maintain, providing a cost-effective solution for material cutting tasks. Package includes: 5 or 10 pieces of wear-resistant or sharp type saw blades, or 10 pieces (5 wear-resistant + 5 sharp type). Note: 1. Due to differences in monitor displays and lighting conditions, actual item color may vary slightly from images. 2. Please allow 1-3 cm variation due to manual measurement. (1 inch = 2.54 cm)
