摘要： A grinding tool has a main body having at least one fiber ply embedded in a binder. An abrasive layer is arranged on the main body. The at least one fiber ply is arranged in the binder in a partially movable manner. As a result, a relative movement that ensures high vibration and noise damping is achieved within the main body and within the at least one fiber ply.
