Abstract: The present invention relates to a novel grinding tool, comprising a substrate with a first water-permeable, flexible textile layer, which comprises multifilaments and to which the abrasive material has been applied, and at least one second layer, which is connected to the surface of the first layer that is free from abrasive material, can absorb water and can be compressed, the abrasive material made up of binder and abrasive grain, selected from the group comprising diamond and cubic boron nitride, being applied to the first layer in such an amount that the grinding tool has a service life of at least two minutes, preferably at least 10 and with particular preference at least 20 minutes, when working a ceramic coating surface by wet grinding.
