Thin, flexible bristles get into hard-to-reach areas. Noncontaminating discs are ideal for cleaning metal surfaces, removing fire scale and oxide, finishing, blending, texturing, prepolishing and polishing all dental acrylics, alloys, and precious metals. The 3M Cubitron and aluminum-oxide grain embedded throughout the bristles enable them to work faster and last far longer than rubber wheels, regular brushes, and buffs. Generate little or no dust or heat associated with rubber wheels and buffs. Work well on all precious and nonprecious dental alloysincluding chrome cobalt, titanium, and stainless steelas well as acrylics and ceramics.
