Turn your Dremel rotary tool into a powerful polisher with the 422 Felt Polishing Cone. Good for polishing metals, plastics, stones, ceramics and glass. The polishing accessory is made to take a semi-rough finish and polish it to a smooth finish. The narrow shape of the accessory is excellent in polishing corners and hard-to-reach places. Works best with the 421 Polishing Compound which allows for a deeper clean of the material and produces a high luster.
