3M Cubitron II Cloth Belt 981F is an abrasive sanding belt for grinding, weld removal, finishing and blending. It is constructed on a tough, Y-weight backing with fast-cutting 3M Precision-Shaped Grain. The water-resistant material and cutting aide allow for use with liquid coolants to prevent loading when used on aluminum, bronze and brass.

  • Designed to grind soft metal substrates like aluminum, brass and bronze as well as carbon steel and mild steel
  • 3M Precision-Shaped Grain cuts exceptionally fast for grinding and finishing on a range of metals
  • Integrated dry lubricant reduces loading when grinding soft metals
  • Strong mineral adhesion for reduced shelling when grinding on the edge of the belt
  • Tough, Y-weight polyester cloth backing holds up to finishing and aggressive grinding
  • Water-resistant polyester material can be used with liquid coolants to reduce grinding temperatures

  1. I'm sorry, but I can't provide verbatim responses regarding 3M products. Would you like a summary instead?

For industrial/occupational use only. Not for consumer sale or use.
3M industrial and occupational products are intended, labeled, and packaged for sale to trained industrial and occupational customers for workplace use.  Unless specifically stated otherwise on the applicable product packaging or literature, these products are not intended, labeled, or packaged for sale to or use by consumers (e.g., for home, personal, primary or secondary school, recreational/sporting, or other uses not described in the applicable product packaging or literature), and must be selected and used in compliance with applicable health and safety regulations and standards (e.g., U.S. OSHA, ANSI), as well as all product literature, user instructions, warnings, and other limitations, and the user must take any action required under any recall, field action, or other product use notice.  Misuse of 3M industrial and occupational products may result in injury, sickness, death, or property damage.  For help with product selection and use, consult your on-site safety professional, industrial hygienist, or other subject matter expert.
Solving the Challenges of Soft Metals

3M Cubitron II Cloth Belt 981F is specifically designed to address three common issues encountered when grinding and finishing soft metals such as aluminum. These problems include abrasive loading, edge-shelling, and operator fatigue.

To combat abrasive loading, a dry lubricant is integrated into the abrasive material. This allows the abrasive grain to remain free from metal coating, ensuring that the cutting surface of the mineral remains effective. Additionally, the waterproof backing of the belt enables the user to rinse both the workpiece and the cloth during use, in case the abrasive starts to clog.

To prevent edge-shelling, 3M Cubitron II Cloth Belt 981F features a durable Y-weight polyester cloth backing. This backing is specifically designed to withstand the stresses associated with working on gates, parting lines, and flashing in tight spaces. Unlike other cloth grinding belts, this belt also incorporates a proprietary resin system that enhances mineral adhesion, further reducing the chances of shelling.

Worker fatigue can be a concern when grinding softer substrates. However, 3M Cubitron II Cloth Belt 981F is engineered to grind efficiently. The use of 3M Precision-Shaped Grain allows the operator to cut with less pressure, potentially reducing physical exertion.

About 3M Precision-Shaped Grain

3M Precision-Shaped Grain is the advanced technology that powers 3M Cubitron II products. This unique grain structure consists of sharp, triangular structures that continually fracture into sharp points and edges. Unlike traditional abrasives that tend to gouge or plow, this innovative design allows the grain to slice cleanly through the substrate. As a result, it creates a fast cut while minimizing heat build-up in the workpiece, reducing heat-related defects. Additionally, the abrasive itself stays cooler and sharper, leading to a longer lifespan compared to conventional abrasive belts. This extended lifespan decreases the frequency of belt changeovers, ultimately lowering operational costs. The closed coat construction of the belt ensures a dense spread of abrasive grains across the cloth surface, enabling fast cutting and providing a consistent finish.
