Conical felt bobs are made of 100% wool felt, mounted on 3/32″, 1/8″ or 1/4″ shanks. These bobs are ideal for use on die grinders, electric drills and air drills. The maximum operating speed is 15000rpm. Conical felt bobs can be used with various polishing compounds or rouges to produce a clean, high finish on molds, dies, models, all metals, plastics, glass or crystal. Great for polishing and buffing all hard to reach surfaces. Three densities are available which include soft, medium and hard.
The felt is prepared in a pattern of layers to allow the flow of cooling air and dissipate heat. Usually used for applying mirror polish with an angle polisher.
