The Cubitronâ„¢ II Advantage
3Mâ„¢ Cubitronâ„¢ ll Hookitâ„¢ Cloth Disc 947A is best suited for metal sanding thanks to its durability and fast cutting abrasive material. Our proprietary 3Mâ„¢ Cubitronâ„¢ II abrasive products have raised the bar for high-performing abrasives. Our engineers started with 3Mâ„¢ 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 Hookitâ„¢ Design
3Mâ„¢ Cubitronâ„¢ II Hookitâ„¢ Cloth Disc 947A is designed with a Hook-and-loop style backing for quick attachment and removal. 3Mâ„¢ Hookitâ„¢ discs are ideal for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. Hookitâ„¢ 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
3Mâ„¢ Cubitronâ„¢ ll Hookitâ„¢ 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 Cubitronâ„¢ ll Hookitâ„¢ Cloth Roll 947A a good match for projects that require an equally durable and aggressive abrasive disc.
