Emery paper is a type of abrasive paper or sandpaper, that can be used to abrade (remove material from) surfaces or mechanically finish a surface. Operations include deburring, polishing, paint removal, corrosion removal, sizing, etc. This is accomplished by rubbing the abrasive-coated paper, with some pressure, against the object being processed. Abrasion may be performed by hand, electrically powered, or air powered equipment.
