Product Description

From the Manufacturer

The 3M™ Utility Cloth Sheet 211K is a versatile light-weight cloth abrasive sheet used on metal, wood, and plastic. Constructed of aluminum oxide in a closed coat, these sheets are ideal for light sanding, eliminating rust, and removing corrosion. The light J-weight cloth backing provides excellent flexibility and resists tears even when twisted or folded. It works well for multiple metalworking applications on both ferrous and non-ferrous metals: deburring operations by hand or by machine; cleaning metals prior to welding; removing rust and other contaminants; blending and repairing metal finishes; fine sanding and polishing applications; and surface preparation for paints and coatings.

Utility cloth sheets are a good choice for general sanding and maintenance of metal or wood surfaces. The cloth backing in sheet form provides the flexibility needed to sand circular edges or small pieces, without tearing as easily as paper or losing grit from folding or bending. On the other hand, the cloth can be torn by hand when a smaller piece is needed, without compromising the sanding surface.

Aluminum oxide 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 abrasives dull more quickly. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.

For more than a century, 3M has applied innovation and technology to improving our customers’ lives and supporting their business goals. Today the company, from its headquarters in St. Paul, Minnesota, serves industrial and commercial customers and consumers in nearly 200 countries. Abrasive Systems products, including a complete line of coated abrasives, microfinishing and microreplicated abrasives, and hardware accessories, provide the finishing touch for almost any surface modification application. The 3M brand, across thousands of products, represents consistency, superior quality, and value.
