Abstract:
A tool for the removal of paint and putty from a primary work surface, the tool comprising:(a) an outer semi-circular assembly comprising circumferential sidewalls, an integral radial backplate, and a semi-circular rigid collar secured therein; (b) rigid disk-like abrading means rotatably and co-axially mounted within said rigid collar of said outer assembly, said abrading means including rigidly disposed abrading elements projecting both axially and radially from a periphery thereof, said abrading means defining a plane of rotation; (c) a motor having an output for high speed rotation of said abrading means, said motor located externally of said assembly; (d) within said rigid collar and in a direction axially opposite of said motor, bearing means for establishing a fixed axial cutting depth relative to said primary work surface, and said bearing means positionable thereagainst, in which said bearing means function as an axial buffer between said abrading means and said work surface and to improve control and mobility of said tool relative thereto; (e) an elongate platform pivotally secured, at one end thereof to said back plate of said outer assembly, said platform normally parallel with said plane of rotation of said abrading means, said motor rigidly secured to a surface of said platform opposite that of said outer assembly; and (f) between said platform and outer assembly, means for tilting said assembly relative to said platform to tilt said plane of rotation of said abrading assembly and to thereby vary depth of cutting thereof in an axial direction upon said primary work surface at that end of said outer assembly at which said tilting means is situated.
