From the Manufacturer
The 3M™ Roloc™ Disc 361F TR consistently provides convenience and high performance for grinding, blending, deburring, and finishing on all metals. The quick and easy Roloc™ attachment system works with your Roloc™ disc pads to make changing discs as easy as a short twist to remove the disc, and a short twist to attach the next disc. Fast-cutting aluminum oxide abrasive grains are bonded to the YF-weight cloth backing with durable, heat-resistant resin. The discs can be used wet or dry.
3M Roloc TR quick change discs are smaller discs that have a plastic threaded button or screw designed to easily and quickly attach to a Roloc TR disc pad (sold separately) so that operators 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. Each TR attachment button is also color-coded to identify its grade, making it easy to grab the grade required for different applications.
Aluminum oxide mineral is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes 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 their fast cut-rate, hardness, strength, and low heat retention, they are widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
Heat-resistant resin is a sturdy binding agent that adheres the abrasive to the backing and maintains the stability of the bond even in conditions of high heat or pressure.
Cloth-backed discs are known for their durability and flexibility. They're a good first choice when working with metal or for heavy wood stock removal.
