3M™ Cubitron™ II Cloth Belt 981F, 2 x 132 in, 60+, YF-weight, Film-lok, 50 ea/Case

3M™ Cubitron™ II Cloth Belt 981F is a revolutionary product designed to solve three common problems associated with grinding and finishing aluminum and other soft metals. These problems include abrasive loading, edge-shelling, and operator fatigue.

To reduce loading when working with aluminum, bronze, and brass, a dry lubricant is integrated into the abrasive. This allows the abrasive grain to be relatively free from metal coating, which keeps the cutting surface of the mineral 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.

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. This helps prevent edge-shelling. Additionally, this cloth grinding belt features a proprietary resin system to improve mineral adhesion, further reducing the chances of shelling.

Worker fatigue can be a concern when grinding softer substrates. 3M™ Cubitron™ II Cloth Belt 981F grinds efficiently, and 3M Precision-Shaped Grain can allow the operator to cut with less pressure, which may help to reduce physical exertion on an operator.

3M Precision-Shaped Grain is the advanced technology behind 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.
