Dozens of vacuum holes throughout these rolls let a sander suck up dust and debris to prevent buildup on your sandpaper. Because there are so many holes, these rolls will work with any vacuum sander, regardless of its hole configuration. They’re coated with the most common abrasive, aluminum oxide, which is hard enough to sand steel and wood. Cut them to any size you need or tear them at the perforated lines every 2 ¾”. Quickly attach, remove, and reuse them using the hook and loop backing.
