Non-woven web discs always require a backing pad for self-fastening discs the NDS 555 by Klingspor

Abrasives are categorised by their intended application and by their materials for which they are ideally used, but also by the material of their backing, their bonding agent and their grain. Also of significant importance is the coating of the grain. Another aspect to consider is the question of whether the abrasive is designed for aggressive sanding or better suited for finishing work, whether it has a long service life and whether its designed for industrial purposes or for private use at home. For all abrasives, however, it is crucial how easy they are to handle. At the top of the comfort handling are non-woven web discs. Since they are self-fastening, these discs can be changed in seconds without the need for any tools.

Non-woven web discs are primarily used in combination with:

• random orbital sanders
• angle grinders
