Silicon Carbide Abrasive This Standard Abrasives™ Quick Change Cleaning Pro Disc is lined with silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. Silicon carbide is a synthetic mineral that is very sharp and commonly used for low-pressure applications such as paint prep. While it breaks down faster than aluminum oxide, it produces a finer finish. This makes the Standard Abrasives™ Quick Change Cleaning Pro Disc best suited for sanding and finishing applications on fiberglass, composite or soft metals. Open Coat Construction Sanding sheets cut better and last longer when dust isn’t clogging the cutting surface of the abrasives. Open coat construction means the abrasive grains are placed with space between them to help evacuate sanding debris and avoid clogging of the cutting edge of the grains. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade. All of this adds up to increased productivity and reduced material consumption. The Quick Release System 3M™ TS and TR quick change discs are smaller discs that have a plastic threaded button or screw designed to easily and quickly screw onto a quick change enabled tool so that you can conveniently change discs with a simple twist-off, twist-on motion. These systems provides a secure attachment even for heavy-duty applications, and the variety of available discs allows swapping from one application to the next in seconds. Each TS and TR attachment is also color-coded to identify its grade, making it easy to grab the grade required for different applications.
