Excellent for platinum, gold, silver, copper, pewter and brass applications! The abrasive in these discs is embedded throughout the material, delivering continuous exposure of a fresh cutting surface. Use 3" discs on a tapered spindle. Flexible, cool-running bristles remove oxides, texture and polish, and refine surfaces without messy compounds.
• Always place discs on the mandrel so that the bristles curve opposite (or away) from the direction of rotation—bristles should not be bent backward during use.
