Turbo-serrated design for more flat, persistent and smooth grinding. Made of heat-treated steel body and high concentration of diamond, these diamond grinding wheels are rist and corrode resistant. These also have a large diamond grind segment for more aggressiveness. Surface coating on concrete, screed and natural stone can also be used to remove adhesives and epoxies. Use soldered single sequential segments wet or dry for quick and smooth grinding with 5mm segment height.
