PFERD fiber discs are manufactured in accordance with ISO 16057 in shape A2 version F under the designation "vulcanized fiber disc". For aggressive grinding with maximum stock removal rate on hard materials that do not conduct heat well. Consistently high performance due to self-sharpening ceramic oxide grain. Active grinding additives in the coating substantially improve the stock removal rate, prevent loading, and result in cooler grinding.
