3M Cubitron II Fibre Disc 987C offers high cut-rates with minimal operator pressure, so tough tasks can be completed with ease. The grinding aid on the disc makes it an ideal choice for a variety of metal types. It helps keep the disc cooler to prevent discolouration and oxidation of heat-sensitive metals such as nickel alloys and titanium, in addition to reducing the risk of heat-related stress cracks. Our discs have 3M Precision Shaped Grain which form triangular points which slice through metal instead of gouging like tradigtional abrasives. These points sharpen themselves as they fracture, making for a swift cut. With its vulcanized fibre backing, it is robust and capable of handling demanding grinding applications. It is excellent for grinding mill scale, pits and blemishes.
