3M 04145, Scotch-Brite Finishing Flap Brush, 8 in x 1 in x 3 in 5A FIN, 7000120562

Scotch-Brite Finishing Flap Brush requires no chemical compounds to achieve fine finishes and is ideal for all aesthetic finishing applications, smoothing wood fibers, defuzzing wood, plastic, and composite surfaces, and sealer scuffing.

This brush is available with aluminum oxide abrasive mineral. 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.

Our 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.
