3M™ abrasive cloth Band 341D is a spiral Band or short tube that conforms to inner and outer contours for sanding and shaping. Fast cutting aluminum oxide abrasive grains are resin bonded to a durable cloth backing to provide fast continuous cut and long life performance. Our Band is a versatile product that can be used for grinding to remove parting lines or seams, imperfections and burrs. It can also be used for shaping and smoothing wood and fiberglass. Our 3M™ abrasive cloth Band 341D fits onto a rubber wheel attachment (such as a cushion polishing wheel or a rubber slotted expander wheel, both sold separately) for use with a die grinder or rotary drill. Our 341D cloth Band is constructed with aluminum oxide mineral, a popular choice among industrial professionals because of its fast cut rate, durability and long life. It can be used on a wide variety of materials in both woodworking and metalworking, including ferrous alloys and is the most commonly used industrial abrasive. The abrasive particles are adhered to the cloth backing with resin, creating a strong bond that withstands high heat and pressure. The Bands come in a range of widths and lengths to suit different contours and tasks and are often used in foundry work. 3M™ 7000139503, Spiral Tube Shaped, Series: 341D, 2 in Band Diameter, 1-1/2 in Band Length, 36 Grit, Aluminum Oxide Abrasive, Cloth Backing, Applicable Materials: Ferrous Alloy, X-Weight Backing Weight
