Abstract
A multi-tasking disk which in one form is used primarily with a powered hand tool to remove measured amounts of material from the surface of a work piece, and, in another form, serving as a buffing tool for removing minute amounts of skin from feet, elbows and the like on a human, or removal of like minute amounts from vegetables. Each disk is formed with an array of either abrading or buffing elements in which each element involves a series of projections having sharpened edges raised above the surface of the disk to accomplish removal of material from the surface upon which it is engaged.
Claims29
An omnidirectional metallic sanding device for use with a hand power tool to remove material from a workpiece comprising a metallic disk, said disk having an array of abrading elements formed thereon;
- each said abrading element being formed with a series of teeth;
- said teeth being positioned within said abrader element so as to provide removal of material from a workpiece regardless of the direction of movement of said disk;
- each said tooth of said abrader element being offset outwardly from the plane of said disk to cause each tooth so as to engage a workpiece and remove material therefrom as said disk is moved there across.
An omnidirectional metallic sanding device for use with a hand power tool for removal of material from a work piece, said sanding device comprising a metallic disk, said disk having teeth formed thereon, each such tooth having at least one sharpened edge;
- said teeth on said disk positioned so that movement of said metallic disk in any direction will result in removal of material from the workpiece;
- each said tooth being offset outwardly from the plane of said disk in order that each tooth is positioned to engage a workpiece and remove material omnidirectionally therefrom as said disk is moved there across.
An omnidirectional abrader element formed on a metallic sanding device, each said abrader element formed with a series of inwardly oriented teeth;
- each said tooth terminating in a sharpened cutting edge, said cutting edge having a bevel formed thereon;
- each said tooth being bent outwardly from the plane of said metallic sanding device so that said sharpened edge thereof extends above the surface of said metallic sanding disk;
- said teeth comprising each said abrader element being so arranged as to thereby provide omnidirectional removal of material from a work piece when said abrader element is moved across the surface of the workpiece.
An omnidirectional metallic sanding device for removal of material from a work piece;
- said sanding device having at least one abrader element, said abrader element being formed by first creating at least one opening in said disk;
- said opening have an interior wall;
- thereafter sharpening edges about at least a portion of said interior wall;
- and offsetting said sharpened edges from the plane of said disk such that said sharpened edges cause removal of material from the workpiece irrespective of the direction of movement of said abrader element.
An omnidirectional metallic sanding device for removal of material from a workpiece;
- said metallic sanding device comprising a metallic disk;
- at least one abrader element formed on said disk;
- each abrader element having an interior wall, at least a part of said interior wall being sharpened to form a cutting edge, and said part of said wall defining said cutting edge raised above the metal plane surface in order that material may be removed irrespective of the direction of the movement thereon.
An omnidirectional metallic device for use in removing material from the surface comprising a metallic disk, said disk having an array of buffing elements formed thereon;
- each said buffing element being formed with a series of sharpened edges;
- said edges being positioned within said buffing element so as to provide removal of material from a surface regardless of the direction of movement of said disk;
- each said edge of said buffing element being offset outwardly from the plane of said disk to cause each edge so as to engage a surface and remove material therefrom as said disk is moved there across.
