Abrasive-particle charged nylon brushes for cleaning, stripping and polishing without scratching or gouging. Polybrushes may be used on wood, metal, stone, etc. for up to 10 times longer than wire brushes. Circular brushes reach into grooves and right angles, the cup brush works on flat surfaces and the split brush works on curved or uneven surfaces. For an optimum result, rotation speed must be between 1250 and 2500 rpm.
