Our quality brushes have a steel hub with 3/32" mandrel arbor for flex-shaft machines. Miniature brushes are great for cleaning and polishing hard-to-reach areas. Overall length is 1-3/4". Sold in packages of 6. These mounted brushes have a 1" diameter brass brush which works best for gold, copper and brass. It is non-sparking, softer than steel and won't scratch soft metals. Use straight wire for stronger cleaning, de-burring and surface cleaning. Precision made excellent quality. Used with a flex-shaft, Foredom or Dremel type rotary tools.
