Use premium cup burs to easily smooth the ends of your wire designs with a few quick twists. Removes rough edges from ear wires in a snap. Just place the wire inside the cup, and rotate the handle back and forth. You`ll wonder how you ever finished ear wires without them.
Works best on 18, 20 and 21 gauge wire. Will not work on 16 gauge wire.
Set of six premium cup burs, made from Swiss tungsten vanadium. Fits into any electric rotary tool that accomodates a 3/32" shank. Pictured pin vise is sold separately.
