This pumice polishing knife-edge wheel from EVE is ideal for use on settings and other metal work without scratching stones. The medium pumice abrasive is safe to use around most stones and buffs out nicks and imperfections in metal surfaces. For best results, use at 7,000–10,000rpm with very light pressure. This wheel has a 1/16" center hole; use with a mandrel (available separately).
Max. speed: 20,000rpm
