3M 7100138167 | 0.500" Diameter x 1.000" OAL x 80 Grit Ceramic Aluminum Oxide Spiral Band

3M cloth band 747D is a versatile abrasive that can be used to access inner and outer contours for grinding, sanding, and shaping on all metals, including stainless steel and nickel alloys, as well as wood and fiberglass. It conforms to contours to remove parting lines or seams, imperfections, and burrs.

For a fast continuous cut and long-life durable performance on aggressive applications, a blend of aluminum oxide and 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 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.

​3M 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 3M cloth band 747D an excellent choice for moderate stock removal and surface preparation.

Features:

• Resin bond withstands high heat and pressure
• Durable cotton backing withstands aggressive sanding and grinding
• Tube-shaped band fits inner and outer contours to remove parting lines, imperfections, and burrs
• Grinding aid reduces grinding temperatures for processes involving heat-sensitive alloys such as stainless steel and nickel alloys
• Ceramic/aluminum oxide blend offers excellent cut rate and life for increased performance over traditional abrasives when sanding on whitewood and metal substrates
