The discs are constructed with a fabric face, foam center, and a grip backing with abrasive grains that are bonded evenly to the fabric face. Openings in the fabric allow water, solvent and air to flow freely around the abrasive. In addition, an open cell design holds large amounts of water or solvent for lubrication and cooling. The foam center also provides even surface pressure that helps eliminate finger marks when hand sanding.
These finishing wheels are available in a grit range from 180 to 4000.
