Cutting and grinding discs are used to cut a wide range of materials, including stone, metal and brick. Use a cutting disc when you need a fast, clean cut in a wall or a piece of equipment. A grinding disc is similar, but one side is finished with an abrasive material that “polishes” surfaces affected by issues such as rust and flaking paint. Available in a range of diameters and brands, there’s a disc here for every imaginable cutting job.
