Our Scotch Brite™ Hookit™ Production Clean and Finish Disc is engineered to achieve the desired finish on solid surfaces, painted panels, and other materials. Non woven, open web runs cool and resists loading to provide a consistent level of abrasive conditioning over the life of the disc. We manufactured Scotch Brite™ Hookit™ Production Clean and Finish Disc using aluminum oxide abrasive, which is a popular choice among industrial professionals because of its fast cut rate and long life. This mineral is a tough, durable abrasive that self fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use. Due to its high cut rate, hardness, strength, and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing use. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys. Scotch Brite™ is a unique surface conditioning product with abrasives incorporated into non woven nylon fibers. Combining abrasives into the fibers creates an abrasive system that delivers consistent results for the life of the product. The open web material is load resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the nylon fibers. We offer a complete line of hook and loop style 3M™ Hookit™ discs for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. They are often used in applications where a 3M™ Stikit™ disc may be too aggressive, as Hookit discs tend to leave finer finishes than adhesive backed discs. Hookit™ sanding discs conveniently and firmly attach to a hook and loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and be used again and again for the extent of the abrasive life.
