3M™ Scotch-Brite™ Roloc™ Disc SC-DR 4" Diameter TR Aluminum Oxide VFN Grit – Pkg Qty 25

The open-web fiber runs cool and resists loading while the abrasives provide a high cut-rate to give you consistent finishing. The 3M™ Roloc™ attachment system offers quick and easy disc change-out, making the Scotch-Brite™ Roloc™ Surface Conditioning Disc ideal for a range of tasks including blending, deburring, and finishing. The Scotch-Brite™ Roloc™ SC Surface Conditioning Disc is available with a choice of silicon carbide or aluminum oxide abrasive mineral. Silicon carbide is a synthetic mineral that is very sharp and commonly used for low-pressure applications such as paint prep and finishing. Aluminum oxide is a hard, blocky mineral that provides high cut-rate and long life. While silicon carbide breaks down faster than aluminum oxide, it produces a finer finish. 3M™ Roloc™ quick change discs are smaller discs that easily and quickly attach onto a Roloc™ disc pad (sold separately) so that you can conveniently change discs from job to job or in multi-step finishing processes. The 3M™ Roloc™ Quick Change Attachment System provides a secure attachment even for heavy-duty applications, and the variety of available 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. Scotch-Brite™ surface conditioning products have been developed by 3M 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.
