Description Cool-cutting cut-off wheels for carbon steel and stainless steel are composed of fiberglass-reinforced ceramic abrasive. Cool-cutting ceramic is a high-density grain that prevent loadings and keeps surface temperatures down when working with heat-sensitive materials such as stainless steel and aluminum. It has a longer lifespan than aluminum oxide and zirconia alumina and self-sharpens faster than other abrasives to remove material faster. WARNING: This product can expose you to chemicals including Lead which is known to the State of California to cause cancer, birth defects or reproductive harm and Butyl Benzyl phthalate (BBP) which is known to the State of California to cause birth defects or other reproductive harm.
