The open-web fiber runs cool and resists loading while the aluminum oxide abrasives provide a high cut-rate for consistent finishing. Our 3M Roloc attachment system offers quick and easy disc change-out, making the Roloc Surface Conditioning Disc ideal for a range of tasks including blending, deburring, and finishing.
We use aluminum oxide abrasive in Scotch-Brite Roloc Surface Conditioning Discs. Aluminum oxide is a popular choice among industrial professionals because of its 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.
We developed Scotch-Brite surface conditioning products with abrasives incorporated into non-woven nylon or synthetic fibers. Combining abrasives with the fibers creates an abrasive system that delivers consistent results for the life of the product. The open-web material runs cool, reducing the risk of part discoloration and warping. The fibers are load resistant and keep the abrasive minerals cutting at high performance by limiting clogging of the fibers, which also extends the life of the disc.
3M Roloc TR quick change discs are smaller discs that have a plastic threaded button or screw designed to easily and quickly screw onto a Roloc TR disc pad (sold separately) so that you can conveniently change discs with a simple twist-off, twist-on motion. The Roloc TR system provides a secure attachment even for heavy-duty applications, and the variety of available 3M Roloc discs allows swapping from one application to the next in seconds.
