3M Scotch-Brite™ GB-DH grinding and polishing wheels are ideal for medium-duty to heavy-duty material removal as well as for finishing work. The combination of abrasive and nonwoven fiber material creates an abrasive system that delivers consistent results throughout the product's service life. The open structure of the material does not heat up during operation and withstands stress, which maintains the high performance of the abrasive minerals by limiting the clogging of the backing fibers. The discs have a tough construction that resists edge wear.
Available in two hardnesses: Heavy Duty (P80) - purple; Super Duty (P50) - blue
