Eraser discs are specialized attachments for rotary tools like grinders or drills, specifically engineered to remove paint, rust, or other surface contaminants. They are invaluable for tasks such as removing bumper stickers, body panels, and rust from metal structures without causing damage to the underlying surface.

These discs feature an abrasive surface made of rubber or synthetic materials that spin rapidly when activated, efficiently scrubbing away unwanted material while minimizing the risk of surface abrasion or damage. 

Available sizes:
