Estimating the term…
A cylindrical cutting element for a cutting machine which includes base ps arranged at a uniform distance from each other. A chisel holder which receives an exchangeable chisel is secured with respect to each base element. The chisel holder has a plug connector which allows the chisel holder to be inserted into a plug receiver of the base element, where it is held by a pressure screw on the base part that grips the plug connector. To relieve the plug connector from the forces acting on the chisel, the base part has a projection which extends in an approximately parallel direction to the running direction of the cutting element and a stop that follows the projection in the running direction and forms an angle therewith. The stop limits the insertion of the chisel holder into the base element and absorbs forces transmitted through the chisel to the chisel holder.
A cylinder-shaped cutting element for a cutting machine having one of a removal and loading screw and a removal spiral comprising a plurality of base elements disposed at even distances and projecting from the cutting element surface, a chisel holder adapted to interchangeably receive a chisel connected to each base element, the chisel holder having a plug connector insertable into a plug receiver of the base element and held therein on the base element by a pressure screw acting on the plug connector, the improvement comprising:
