Excellent on marble, quartz/terrazzo/concrete, china clay, enamels/porcelain, fiberglass, removing epoxy, glue or urethane,coatings mastiks. Intended to be mounted on hand grinding machines with a proper backing pad, it acquires its flexibility after a few minutes from beginning of working. Therefore the flexibility shall never be tested by hand in a cold condition. The flexibility allows to deaden vibrations that normally occur with the use of grinding wheels, reduces and facilitates the operator's labour while providing an excellent performance. To achieve the best efficiency of the disc, just exert a slight pressure during working. Rubber backing pad required Specify Grit please 16g, 24g, 36g, 60g. I have 100mm, 115mm, and 125mm
