Bands: 3M™ Cloth 747D - Custom Sizes

Our 3M™ Cloth 747D is made with a blend of aluminum oxide and 3M™ ceramic grain and is designed for superior metal finishing on a variety of metals including nickel and stainless steel.

  • Excellent belt for stroke sanding on many metals including stainless steel
  • Anti-friction backing helps abrasive run smooth
  • X-weight cotton backing withstands aggressive sanding and grinding
  • Grinding aid helps reduce heat and grinding temperatures
  • Delivers exceptional finishes on a variety of metal substrates

Delivers exceptional finishes on a variety of metal substrates

Our 3M™ Cloth 747D features an anti-friction coating, which helps the abrasive run smoothly over the workpiece, including stationary platens that remain static while grinding. This attribute, combined with the semi-flexible X weight backing, make Cloth 747D a good match for projects that require an equally durable and malleable abrasive. The grinding aid on Cloth747D is an added coating that helps the abrasive stay cool during grinding, minimizing heat and improving abrasive performance. 

Ceramic aluminum oxide blend offers excellent cut rate and life for better performance

Cloth 747D is engineered using 3M™ ceramic grain, which enhances 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 747D an excellent choice for moderate stock removal and surface preparation.

Bands: 3M™ Cloth Band 341D

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.

  • Tube-shaped band fits inner and outer contours to remove parting lines, imperfections, and burrs
  • X-weight cloth backing withstands heavy sanding and grinding
  • Resin bond withstands high heat and pressure
  • Tough aluminum oxide abrasive mineral cuts fast and performs well on many substrates
  • Bands fit onto a rubber expander wheel attachment (sold separately) for use with a die grinder or rotary drill

 

Good for Shaping and Smoothing

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.

Bands: 3M™ Cloth Band 747D

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.

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

High Quality Construction

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. 

Blended Abrasive Grain

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.
