3M ceramic aluminum oxide blend is a ceramic mineral designed using a proprietary process to enhance toughness and hardness of the grain for a higher level performance. Ceramic aluminum oxide blend is engineered to fracture frequently and surpasses aluminum oxide abrasives in both cut-rate and durability. Perfect for moderate to heavy stock removal as well as finishing, ceramic abrasives are built to cut fast and handle intense heat and stress applications.

Scotch-Brite abrasives are unique surface conditioning products with abrasives incorporated into non-woven fiber matrix. Combining abrasives and non-woven material creates an abrasive system that delivers consistent results for the life of the product. The open-web material runs cool and is load resistant, which keeps the abrasive minerals cutting at high performance by limiting clogging of the fibers.
