For a fast continuous cut and long-life durable performance on aggressive applications, a blend of aluminum oxide and our 3M™ Ceramic Abrasive Grain is resin-bonded to a durable cotton backing. Resin creates a strong bond that withstands high heat and pressure, and a grinding aid on the band reduces grinding temperatures to protect heat-sensitive alloys. The band 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. The bands come in a range of widths and lengths to suit different contours and tasks, and are often used in foundry work. Our ceramic abrasive grain is a ceramic mineral designed using a proprietary process to enhance toughness and hardness of the grain. Ceramic blend products feature aluminum oxide blended with ceramic grain for a harder, longer-lasting abrasive. Perfect for stock removal, ceramic abrasives are engineered to fracture frequently for a super fast cut and can handle intense heat and stress applications. Ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability and makes our 3M™ Cloth Band 747D an excellent choice for moderate stock removal and surface preparation.
