The Bosch Professional J450 Expert for Wood and Paint sanding roll offers an excellent material removal rate on wood and painted surfaces. Its tough, semi-friable aluminum oxide abrasive grit coating ensures a consistently high material removal rate. The flexible J-cloth backing allows for sanding on contoured workpieces and difficult areas, making it ideal for solid wood as well as removing paint, lacquer, and veneer. This roll is easy to rip to any desired size and shape, tearing straight along the length and width, and is suitable for hand sanding and orbital sanders with clamp attachments.
