CTISMICE 1 Inch Radial Bristle Disc for Jewelry, Wood, Metal and other Small Parts Polishing Buffing Specification: Shank Diameter: appr. 1/8'' (3 mm) Shank Diameter: appr. 3/32'' (2.35 mm) Disc Diameter: appr. 1'' (25mm) Disc Center Hole: 0.08'' (2mm) Material: Nylon + Aluminum Oxide Grains Important Notice: 1. Installing the bristle disc the right way and operating the rotary tool the right way will give you a truly great polish. 2. These get used up rapidly under any use application that has a high RPM. I would suggest only using these at the lowest speed situations. If you can use a different option, then do that. 3. These are not high-speed discs, so set your tool to about 15,000 RPM and let the disc do the work. 4. Slowly touch the material surface, it is not recommended to apply a large amount of pressure at once.
