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

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 lubricant 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.

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

Worker fatigue is a common concern when grinding softer substrates. However, the efficient grinding action of the 3M Cubitron II Cloth Belt 981F, combined with the use of 3M Precision-Shaped Grain, allows operators to cut with less pressure. This can help reduce physical exertion and minimize operator fatigue.

About 3M Precision-Shaped Grain

3M Precision-Shaped Grain is the advanced technology utilized in 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 precision-shaped grain slices cleanly through the substrate. This results in a fast cut and reduces heat build-up in the workpiece, minimizing heat-related defects. Additionally, the abrasive itself stays cooler and sharper, leading to a longer lifespan compared to conventional abrasive belts. This reduces 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.
