3M™ Cubitron™ II Hookit™ Cloth Disc 947A offers revolutionary performance with 3M Precision Shaped Grain on an X-weight polyester-cotton cloth backing. Our high-performing disc contains a grinding aid, making it ideal for medium to high pressure applications on stainless steel and other exotic alloys, along with carbon steel, cobalt chrome, and nickel alloys.
The Cubitron™ II Advantage
3M™ Cubitron™ ll Hookit™ Cloth Disc 947A is best suited for metal sanding thanks to its durability and fast cutting abrasive material. Our proprietary 3M™ Cubitron™ II abrasive products have raised the bar for high-performing abrasives. Our engineers started with 3M™ Ceramic Abrasive Grain and electrostatically oriented 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 self-sharpen as the points break off, ensuring extended high performance in heavy-duty production applications. The grains wear evenly and provide extra-long life and consistency .
The Convenience of Hookit™ Design
3M™ Cubitron™ II Hookit™ Cloth Disc 947A is designed with a Hook-and-loop style backing for quick attachment and removal. 3M™ Hookit™ discs are ideal for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. Hookit™ sanding discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, and can be re-used again and again for the extent of the abrasive life.
Tough, Durable and Heat Resistant
3M™ Cubitron™ ll Hookit™ Cloth Disc 947A features both an anti-friction grinding aid and a resin coating, which helps the disc run cool during high pressure applications, and helps prevent metal surface discoloration. The sturdy, X-weight backing gives excellent strength and durability to the disc, and allows for more aggressive use for longer periods. These attributes make Cubitron™ ll Hookit™ Cloth Roll 947A a good match for projects that require an equally durable and aggressive abrasive disc.
What makes 3M ™ Cubitrom II ™ abrasives so special??
The secret behind the revolutionary performance of Cubitron™ II abrasives lies in their Precision-Shaped Grain (PSG) Technology — the result of decades of technological advances in ceramic abrasive and microreplication technologies. These precision-shaped grains are uniformly sized triangular structures that are super-sharp and evenly distributed onto the backing, allowing them to slice through material like a knife through butter rather than gouging or plowing as other abrasives. These triangular shaped grains are electrostatically oriented on the backing with their cutting edges facing the work surface for the most efficient cut and even wear. As the triangular shaped grain wears, the cutting edge continuously fractures to form new, sharp points and edges that continue to slice through material, wear evenly, provide super-long life and produce a consistent finish. This allows 3M Cubitron II ™ belts and discs to run cooler and keep on working—long after conventional abrasives have dulled, shelled, glazed over and been thrown out. Conventional abrasives tend to be irregular and blocky in shape. So, instead of a clean, machining action, conventional grain tends to “plow” through material, causing heat to build up both in the workpiece and the abrasive — resulting in a slower cut, shorter abrasive life and a lower quality finish. Cubitron II ™ abrasive discs are available resin-bonded to a stiff, super-tough, tear-resistant film backing offering greater tear resistance than paper discs providing greater durability and edge retention. Cubitron II ™ discs and belts lasts significantly longer than conventional abrasive allowing more parts to be sanded per disc with fewer disc changes.
