Abstract
A tool for a street milling, coal-cutting mining machine or the like which includes a chisel with a chisel head and a chisel stem. The chisel stem is rotatably mounted in a receiver of a chisel holder. A perforated wearing protection element is mounted on the chisel head. The chisel head sits closely on the chisel holder while embracing the interposed wearing protection element. This invention achieves improved wearing protection behavior of such a tool. Thus, the inventive wearing protection element has one or more spring elements that elastically support the chisel head by way of the chisel holder.
