Ceramic Conical Burrs are made of inorganic materials such as alumina which are sintered at temperatures above 1300 degrees Celsius. The special properties of the materials make the ceramic grinding burr cores have the characteristics of high hardness, wear resistance, fast heat dissipation, corrosion resistance, safety and environmental protection,perfect for the defects of plastic or metal grinding cores. Besides, ceramic grinding core performance is stable and cheap, so it is more and more widely used by the market.
