High Quality ConstructionOur 3M™ Cloth 990FZ is best suited for woodworking due to its durability and fast cutting abrasive material. Its tough, polyester cloth backing provides smooth operation and durability for consistent finishing. The abrasive side features an open coat construction and an anti-static treatment to help prevent debris from loading on the belt and limiting sanding ability.Precision Shaped GrainsThis belt uses revolutionary precision shaped ceramic grain to slice cleanly through wooden surfaces, rather than gouging or plowing as traditional abrasives do. This creates a super-fast cut and reduces 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 ceramic grain belts, decreasing costs and reducing belt changeovers.The Cubitron™ II AdvantageOur proprietary 3M™ Cubitron™ II products have raised the bar for high-performing abrasives. Our engineers started with 3M™ Ceramic Precision Shaped Grains and used technology to electrostatically orient each triangular structure on the backing to form sharp peaks and maximize cutting potential. These peaks act like individual cutting tools that slice through wood, ensuring extended high performance in heavy-duty production applications. The grains wear evenly and provide extra-long life and consistency with less grinding pressure., maximizing productivity and minimizing belt stress and operator fatigue.
