Heavy-duty aluminum oxide flexible sponge-backed discs with hook and loop backing. Developed for tackling both smooth and profiled surfaces. Its patented, flexible construction allows it to create a smooth sanding pattern on angled surfaces and edges while minimizing the risk of pressure marks. The flexible weave also allows water and air to pass freely, making it suitable for both dry and wet sanding, by machine or by hand.
Washable and reusable, one piece can replace several pieces of ordinary sanding discs.
