A high performing sandpaper that works well for most substrates.
The 3M™ sandpaper comes in a range of grades and sizes to accommodate many different projects. The paper backing is durable enough for coarse sanding, yet flexible enough to be used on curved surfaces. This sandpaper's cut rate and durability make it an excellent choice for blending the joints of connecting pieces in wood and metalworking.
Aluminum oxide is a very hard mineral that maintains sharp points on the grains much longer than natural abrasives such as emery or garnet. Open coat construction helps minimize the buildup of dust on the surface of the paper, which would otherwise load the abrasive points. Loading often results from sanding soft materials and can clog the abrasive, shortening the usable life of the sandpaper sheet.
