Diamond Carbide Pin Set of 3

Description

ROISOS Coin Cleaning Diamond Carbide 3-PIN SET Extremely fine grit. SET OF THREE DIAMOND CARBIDE PINS for coin cleaning One flat pin, one pointed pin, one round pin. —The highest quality, extremely fine grit diamond carbide pin available. —This is the best possible diamond carbide pin for cleaning coins. Virtually unbreakable shank. The grit is fine enough to gently file away dirt without damaging the metal or patina, as long as the cleaning is done properly. —Most diamond pins on the market are NOT SUITABLE for coin cleaning because they are too coarse (even though they may have yellow bands and be described as “very” or “extremely fine”) and will damage the metal and patina. Pins wear out: Use them to file away soil deposits, not hard, mineralized encrustations. Apply gentle but firm pressure in a rolling motion around the pins.
