This polishing set includes one 3/32" and one 1/8" stainless steel shank mandrel, along with 21 total of 3M radial discs that measure 3/4" (includes 3 of each disc grit in pink, peach, light green, yellow, white, red, and blue). The bristles are an ideal, convenient polishing tool, and feature a fine and long-lasting abrasive within the flexible bristles that are able to reach small, hard-to-reach, or curved areas and surfaces. These 3M Radial Bristle Discs are embedded with a long-lasting abrasive material which eliminates the need for messy compounds. Flexible and cool-running bristles are great for cleaning and removing dirt, rust, and oxidation without damaging the underlying surface. Use on platinum, gold, silver, pewter, aluminum, steel, and stainless steel. They can get into small grooves and fine details with ease and can be used on most metals. Since the abrasive is integrated into the bristles, no compounds or chemicals are needed. 3M discs are mounted in screw-top mandrels singly or in multiples. Maximum speed is 30,000 RPM. The included mandrels are ideal for rubberized abrasives and buffs. Use with wheels having 1/16" (1.6 mm) arbor holes. Use 3 to 6 discs per mandrel for best performance. They produce a uniform finish that is easily controllable. Great conformability and flexibility, which easily finishes detailed or hard to reach areas. Runs clean; therefore no chemicals or compounds are required. Runs cool, which means that they are safe for delicate pieces.
