3M™ 7000120803 Surface Conditioning Disc, 7 in Dia Disc, Coarse Grade, Aluminum Oxide Abrasive, Paper Backing

Scotch-Brite™ SE surface conditioning disc combines an aggressive, non-woven disc to perform heavy duty deburring and finishing with the efficiency of a hook and loop attachment system. Our heavy duty non-woven fiber construction conforms well to help preserve edges as well as irregular or contoured surfaces. Our Scotch-Brite™ SE surface conditioning disc uses aluminum oxide abrasive. Aluminum oxide is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use. Due to its high cut rate, hardness, strength and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing use. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys. Scotch-Brite™ industrial abrasives are unique surface conditioning products with abrasives incorporated into non-woven nylon or synthetic fibers. combining abrasives with the fibers creates an abrasive system that gives you 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.
