The 1FS HARD disc is a highly durable pre-polishing wheel designed for aluminum and stainless steel surfaces, especially those that are rough or poorly prepared. Made from an extra-hard, impregnated fabric, this disc provides aggressive cutting action ideal for the initial stage of mirror polishing.
When combined with 1FS HARD paste, it quickly levels uneven areas, removes oxidation, deposits, flash rust, and scratches caused by 600–800 grit sandpaper or non-woven abrasives.
