POLINOX grinding discs consist of non-woven polyamide abrasive, into which abrasive grain is integrated. The non-woven and abrasive-cloth flaps are stuck to a glass-fabric backing pad, meaning that the discs can be used face-down on large surfaces. A long tool life is achieved through the dense packing of the flaps. The tool is designed for working on large surfaces with speed-adjustable angle grinders.
