The 3M™ Utility Cloth Roll 314D provides lightweight cloth sanding strips used for many hand sanding applications. Constructed with aluminum oxide mineral, the utility roll comes in a range of grades for common applications such as deburring, blending, and repairing metal finishes, removing rust or other contaminants, and surface preparation for paints and coatings.The desired length of the strip can be torn from the roll for a specific application. Most grades have a light, J-weight cloth backing that provides the flexibility needed to conform to circular edges, angles, or other contours. Rolls in grades P50 or P60 have a slightly stiffer X-weight backing suitable for more coarse sanding applications. Cloth remains durable even when bent or rolled, without tearing or shelling, but strips can be torn by hand when a smaller piece is needed, without compromising the sanding surface. Aluminum oxide is a popular choice among industry professionals because of its fast cut rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional abrasives dull more quickly. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
