#39-002 MAGNETIC FINISHERS CLEAN UP AFTER SOLDERING, SIZING, OR SETTING PROVIDING A PRE-FINAL POLISH IN JUST MINUTES.  THE TINY NEEDLE-LIKE STAINLESS SHOT GETS INTO SMALL PLACES DURING ROTATION THAT POLISHING WHEELS CANNOT.  THEY REMOVE SCRATCHES AND SMOOTHE SURFACES WITHOUT TAKING AWAY ENGRAVING DETAIL, LETTERING OR LOGOS.
