3M Silver T41 cutting discs offer an unbeatable price-to-performance ratio. They contain precisely shaped abrasive grains in the form of miniature triangles, designed to fracture as they wear. This continuously creates new ultra-sharp points and edges that dig into the metal like a knife, instead of merely abrading or roughening it. They thus offer a much longer service life than conventional ceramic abrasives. The discs enable fast cutting of metal pipes, tubes, and sheet metal.
