Vulcanised fibre discs (commonly known as: fibre discs) are round grinding wheels with a backing made of vulcanised fibre that is coated on one side with resin and abrasive grain. Fibre discs are fitted to suitable backing pads and used on angle grinders, predominantly for machining metal.

Fiber discs are the most classic of grinding product designs using a heavy-duty coated abrasive disc with resin over resin construction on heavy-duty vulcanized fiber backing. Ideal for general purpose applications ranging from heavy stock removal to surface blending used with a back-up pad on portable angle grinders.
