Dissolve microscopic surface flaws from metal parts for a mirror-like finish. These electropolishers send current through a conductive solution (sold separately) to remove a layer of surface material. They’re ideal for polishing intricate parts with hard-to-access features. Because they remove material evenly, they’re also good for applications where you need to polish your part without altering its dimensions. They’re small enough to fit on your workbench. Only use them on stainless steel and chrome workpieces.
