With this versatile capability, the Scotch-Brite(TM) Roloc(TM) SL Surface Conditioning Disc 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 product life. These same attributes allow you to use less pressure, reducing fatigue and maximizing disc life. Scotch-Brite(TM) Roloc(TM) SL Surface Conditioning Disc use aluminum oxide abrasive. 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. 3M(TM) Roloc(TM) TR quick change discs are smaller discs that have a plastic threaded button or screw designed to easily and quickly screw onto a Roloc(TM) 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 our 3M Roloc discs allows swapping from one application to the next in seconds. Each TR attachment button is also color-coded to identify its grade, making it easy to grab the grade required for different applications.
