Improvements to sanding techniques often seem few and far between. The addition in the past couple of years, of the soft sanding pads was received with great enthusiasm. Turners were especially excited, but great care had to be taken to make sure that the edges of the discs didn't gouge the workpiece. So here's the answer to that problem our new Scalloped-Edge discs. The scalloped edges wrap around the edge of the sanding pad so there's no sharp disc edge to scratch your work. These discs are made from our most popular sanding material- the now-famous KLINGSPOR aluminum oxide stearate. You'll realize exceptional life along with exceptional finishes.
