3M 28200, Flexible Foam Sanding Sponge, Fine, 4-1/2 in x 3-3/4 in x 3/16 in, 7010361110

Its flexible, soft-back foam helps in effectively sanding curves, creases, contours, and other hard-to-reach areas. The unique microreplicated texture on the back of our 3M™ Flexible Foam Sanding Sponge is soft, comfortable and provides a better grip than smooth backed sponges. Flexibility also helps the sanding sponge release particles and reduce loading. Sized for hand sanding, the reusable foam sanding sponge bends, folds, twists to follow contours.

3M™ Flexible Foam Sanding Sponge contains aluminum oxide abrasive mineral, which 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 for sanding and finishing applications. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys.
