 Disks are available for steel and stainless steel.Abrasive saws can also use superabrasive (i.e., diamond and cubic boron nitride or CBN) blades, which last longer than conventional abrasive materials and do not generate as hazardous particulate matter.Superabrasive materials are more commonly used when cutting concrete, asphalt, and tile; however, they are also suitable for cutting ferrous metals.
