Extra Fine Diamond Bit (E12X)

Used with a small amount of buffing oil, this Bit can give you a finish that's almost a high shine. Remember that you must graduate from lower to higher grits in order to get a fine finish on acrylic nails. Start with a Coarse (E12C), then Medium (E12M) Bit when shaping the nail. Be sure to go over every part of the nail thoroughly before switching to finer grit. Then refine the nails with the Extra Fine Diamond (E12X) Barrel Bit followed by the soft side of a white block buffer.
