Use Wet or Dry Used with water, 3M™ Wetordry™ Cloth Discs 281W help users rinse areas of the workpiece during finishing. It prevents dust and debris from clogging the abrasive and keep cutting fast.These versatile discs are ideal on e-coat primer and wood and may also be used dry for finishing metal and gel coats. In the marine industry, they are used for sanding old finishes, fine feather edging and surface work. Our 3M™ Wetordry™ Cloth Discs 281W are made with aluminum oxide mineral, which is a popular choice among industrial 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 natural minerals dull more quickly. Due to its fast cut-rate, hardness and strength, it is widely used in grinding applications, as well as sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys. The Benefits of Cloth-Backed Discs We engineer our 3M™ Wetordry™ products to include our proprietary waterproof cloth backing, which supports both wet and dry applications. Cloth-backed discs are known for their durability and flexibility; they're a good first choice when working with metal or for heavy wood stock removal. At the same time, these applications tend to produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. These effects may be minimized by sanding with water to rinse dust away from the workpiece and the abrasive surface.
