| In a first embodiment, the invention is a scraping tool having a tool body which is adapted to support one or more rotatable cutters. Each cutter is not powered to rotate but is able to rotate freely about a first axis of rotation. Each rotatable cutter has one or more cutting edges or points arranged in a generally circular pattern in a first plane. The tool is configured such that the first plane can be presented at an acute angle to a surface to be scraped. In a second embodiment the invention is a rotary tool adapter, having the same features as the scraping tool, but with the added feature that it can be rotated about a second axis of rotation by a power tool. The rotary adapter further includes a pivot member which can help to control the application of the cutters onto a surface to be cut or scraped. | ||||||
