Highlights
- 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
- Durable resin bonding resists deterioration from heat, extending the life of the abrasive cloth

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.

3M Precision-Shaped Grain
Backstand grinder application on cast aluminum
3M™ Cubitron™ II Cloth Belt 981F is designed to solve three common problems associated with grinding and finishing aluminum and other soft metals: abrasive loading, edge-shelling and operator fatigue.
To help reduce loading when working with aluminum, bronze and brass, a dry lubricant is integrated into the abrasive and allows the abrasive grain to be relatively free from metal coating them, allowing the cutting surface of the mineral to remain effective. The waterproof backing also enables the user to rinse areas of the workpiece and the cloth during use, in case the abrasive begins to clog.
To help prevent edge-shelling, our 3M™ Cubitron™ II Cloth Belt 981F features a durable, Y-weight polyester cloth backing that stands up to the stresses of working on gates, parting lines and flashing in tight spaces. Plus, unlike other cloth grinding belts, ours features a proprietary resin system to improve mineral adhesion, further reducing the chances of shelling.
Tough, Y-weight backing is ideal for stroke sanding applications
About 3M Precision-Shaped Grain
3M Precision-Shaped Grain is the advanced technology behind our 3M™ Cubitron™ II products. Its sharp, triangular structures continually fracture into sharp points and edges that slice cleanly through the substrate, rather than gouging or plowing as traditional abrasives do. This creates a fast cut and minimizes heat build-up in the workpiece, reducing heat-related defects. Moreover, because the abrasive itself stays cooler and sharper, it lasts significantly longer than conventional abrasive belts, decreasing the number of belt changeovers to lower operational costs. Its closed coat construction features a dense spread of abrasive grains across the surface of the cloth, cutting fast and providing a consistent finish.
