The ERSTA NTS fiber grinding disc is designed for machine grinding. It is used for processing hard surfaces such as steel, non-ferrous metals, or wood. The grain is made of aluminum oxide, which ensures long-lasting grinding. The applied binder is made of special synthetic resins that excellently hold the abrasive material on the substrate and prevent it from chipping. The fiber carrier is resistant to damage during work, such as tearing. The closed coating ensures the least possible wear of the disc during material processing. We have a choice of grits from P36 to P120. The abrasive disc is adapted for use on a mechanical device with a rotational speed not exceeding 13,300 rpm.
