This 86 piece Sunburst® Assortment contains twelve each of 7/8" radial discs in all grits plus two mandrels.
Sunburst® Radial Bristle Discs are some of the best finishing & polishing tools for small and hard to reach areas without removing detail or causing flat spots. They work faster than other flex shaft attachments and last for longer. The specially treated ceramic abrasive grain embedded throughout their thin flexible bristles allow them to generate minimal dust and heat. These don't need polishing compound either.
Recommended operating speeds for most applications is 3,000-18,000 RPM. Lower speeds allow a softer touch, greater flexibility and more subtle results, while higher speeds will remove more material and create a higher polish. The direction of rotation should go with/in the same direction as discs - should not bend back disc bristles. Use at least three to six discs per mandrel.
Use in progression (yellow - white - red - blue - pink - peach - green) to adequately achieve your desired finish.
Pink - peach - green discs will not scratch stones.
