Scotch-Brite™ Roloc™ Surface Conditioning Disc, SC-DR, SiC Super Fine, TR, 4 in, 25/Carton, 100 ea/Case

The open-web fiber runs cool and resists loading while the aluminum oxide abrasives provide a high cut-rate for consistent finishing. The 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.

Aluminum oxide abrasive is used 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.

Scotch-Brite™ surface conditioning products were developed 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.

• GREAT FOR LOW-TO-MEDIUM PRESSURE: Built for consistency in blending, cleaning, deburring, finishing, grinding, polishing, radiusing, refining, and surface preparation, depending on the chosen grade
• CONFORMABLE NONWOVEN WEB: Springy nonwoven fibers resist loading, conform to irregular or contoured surfaces, and minimize undercutting and gouging
• WORKS ON A RANGE OF METALS: This multipurpose option is great for use on aluminum, mild steel, nickel alloy, stainless steel, and titanium
• QUICK AND EASY ATTACHMENT: Convenient 3M™ Roloc™ Attachment System allows for fast disc changes
• CHOOSE YOUR MINERAL: Discs are available either powered by super-sharp silicon carbide (SiC) that excels in low-pressure and fine finishing applications or made from harder and more durable aluminum oxide (A/O)
• AVAILABLE IN A RANGE OF GRADES: Choose from Super Fine (SFN), Very Fine (VFN), Medium (MED), and Coarse (CRS) to fit your application needs
