The Rectifier™

Sand and file your pieces perfectly every time! The Rectifier is magnetic, so when placed on a steel bench block it stays in place. Magnetize a flat file to the side or use the removable magnetic piece to securely place a piece of sandpaper and refine edges perfectly flat. It doesn't stop there! This handy tool features a hole in the top, designed for placement of a mounted sandpaper cartridge roll to refine the inside of your ring or round object.
