Standard Frosted Design: Stone drill bit adopts standard frosted design. The brass core reduces shaft binding, effectively preventing the grinding material from sticking to the grinder shaft. The joint is plated with diamond grit, and the joint is double-layer electroplated to ensure that the diamond grit does not peel off, maintaining high strength and long service life. Material: Diamond drill bit is made of brass and diamond, and adopts chrome plating and hardening to improve the hardness and wear resistance of grinding. It can be used for a long time and efficiently, and no need to replace it frequently, which saves time and costs. [High Standard Assurance] Each diamond drill bit can control and test the quality, meeting high standards and providing you with professional quality assurance so you can use it with confidence. and efficient: The diamond drill bit is well designed to complete grinding tasks quickly and efficiently, whether it is a simple repair job or a complex project. Scope of application: Ceramic abrasive tool is suitable for molding hard materials such as ceramic tiles, glass, colored glass, stone, etc. It is compatible with various glass grinders and can meet your needs for different materials and equipment.
