Damage prevention tool and method
Abstract:
A damage prevention tool and method is provided in which a free-floating disk is connected to an abrasion disk through a bearing structure. When the tool is actuated, the abrasion disk rotates substantially independent of the floating disk. The floating disk may have a slightly larger circumference and a non-marring friction material on its outer edge, such that the outer edge does not damage foreign objects and protects the abrasion disk, and the abrasion material mounted to the abrasion disk, from contacting foreign objects.
