Due to its density and purity, this particularly high-quality felt polishing wheel can be used to remove light scratches, stains and discoloration from real glass panes, and we strongly recommend the use of glass polish, as this has a very positive effect on the polishing process. The polishing wheel is characterized by very low abrasion and therefore a very long service life. Use with a standard drill or cordless screwdriver (speed up to 3000 rpm).
