This type of driver has been designed to hold the abrasive paper discs for cleaning and polishing parquet floors, plank floors and block floors. Depending on the type of floor to be treated and on the state of the floor traiter (new or old floor, degree of wear etc), various types of sandpaper of different granulations are used. The type of paper and the material used to make these sandpaper disks have been appositely studied by the firm C.C.A.G. Crotti who vouchsafes for the excellent quality and performance of the product. The colour has nothing to do with the quality, but is meant to facilitate ordering and utilization. These disks can be double faced, or one faced.
