Precision Shaped GrainsThe 3M™ Cubitron™ II Cloth Roll 784F uses a revolutionary precision shaped ceramic grain that continually fractures into super-sharp points and edges that slice cleanly through metal, rather than gouging or plowing as traditional abrasives do. This creates a super-fast cut and lessens heat build-up in the workpiece, reducing heat-related stress cracks and discoloration. Moreover, because the abrasive itself stays cooler and sharper, it lasts significantly longer than conventional ceramic grain belts, decreasing costs and reducing product changeovers.Durable DesignThe exceptionally fast cut and long life of the precision shaped ceramic grain make this roll ideal for industrial environments. It is also heat resistant, produces a uniform finish over the life of the product, and helps eliminate burning during grinding and finishing applications. The Y-weight backing on the 784F roll provides durability and the mineral is resin bonded to the backing for reliable performance, even under moderate heat and pressures.The Cubitron™ II AdvantageOur proprietary 3M™ Cubitron™ II abrasive products have raised the bar for high-performing abrasives. Our engineers started with 3M™ Precision Shaped Ceramic Abrasive Grain 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 metal, and continuously shelf-sharpen as the points fracture, ensuring extended high performance in production grinding and finishing applications. The precision shaped grains wear evenly and provide extra-long life and consistency with less operator grinding pressure. The result is that Cubitron™ II products out-cut and outlast every conventional ceramic industrial abrasive product on the market, maximizing productivity and minimizing belt stress and operator fatigue.
