IMPROVEMENTS IN METAL SANDING DEVICES

摘要

A metallic disk (10) for use with a powered hand tool to remove measured small amounts of material from the surface of a workpiece to smooth the surface thereof. Each disk (10) being formed with an array of strategically placed abrader elements (14) in which each such abrader element (14) is formed with a series of projections (38) in the nature of teeth extending inwardly from an inner wall, defining an opening, toward the edge of the abrader element (14), and being raised above the surface of the disk to engage the surface of the workpiece.
