3M 33792, Scotch-Brite Roloc SL Surface Conditioning Disc, SL-DR, A/O Coarse, TR, 3 in, 7100029968, 100 per case

With this versatile capability, our Scotch-Brite Roloc SL Surface Conditioning Discs can reduce or eliminate subsequent conditioning steps for weld clean up, grindline refinement, metal blending, and even light deburring. Available in four grades: Medium, Coarse, Heavy Duty and Super Duty, the open-web, non woven SL disc runs cool, resists loading, and maintains cut-rate consistency throughout the life of the disc. These same attributes allow you to use less pressure, reducing fatigue and maximizing disc life.

We use aluminum oxide abrasive mineral in the Scotch-Brite Roloc SL Surface Conditioning Disc. 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 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.

3M Roloc TR quick change discs are smaller discs that quickly attach onto a Roloc disc pad (sold separately) so that you can conveniently and quickly change discs as needed. Our Roloc TR and TSM systems provide a secure attachment even for heavy-duty applications, and the variety of our other 3M Roloc discs allows swapping from one application to the next in seconds. Each disc is also color-coded to identify its grade, making it easy to grab the grade required for different applications.

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.
