摘要： A chisel holder for a road milling machine or the like, having a base element which supports a holding neck, wherein the holding neck has a chisel receiver and a protrusion is connected to the base element upstream of the holding neck when viewed in an advancing direction of the tool. For improving the cutting output, in particular in connection with rough-chipped milling materials, the base element has a connecting section designed as a chip breaker, which is formed on the base element and extends, starting at the holding neck, at least partially over the protrusion.

摘要： A cylindrical cutting element for a coal cutting machine with a reamer-conveyor worm or reamer spiral for a coal cutting, disposed projecting at a distance from the surface of the cutting element and comprising base elements attached at uniform distances. A chisel holder with an exchangeable chisel is connected to each base element. The chisel holder is inserted with its plug-in connector into a socket of the base element and is maintained therein by a pressure screw. A time-saving assembly of a cutting element, wherein the base elements can be positioned on and fastened to the surface of the cutting element in a simple manner is attained where receiver pockets are cut along the reamer-conveyor worm or reamer spiral at uniform distances into the surface of the cutting element, the undersides of the base elements end in a base whose cross section is matched to the receiver pockets, and the base elements are introduced, positioned by the base, into a receiver pocket and are fixedly connected thereto.

摘要： A tool holder including a tool box with a tool seat in a holding projection for receiving a tool in such a manner that it can be replaced. The tool seat is configured as a bore and has a tool insertion opening. The tool holder has a fastening side with a fastening projection and, facing away from said fastening side, an exterior, and during use of the tool centrifugal forces are effective in the direction from the fastening side to the exterior. This invention ensures the free rotatability of a tool inserted in the tool holder even if overburden material enters the tool seat. For this purpose, the holding projection has an opening penetrating the inner wall of the tool seat and creating a spatial connection to the exterior, and the opening opens the tool seat towards the exterior.

摘要： A round shaft chisel with a clamping sleeve, wherein the round shaft chisel has a chisel head and a chisel shaft rotatably maintained in the clamping sleeve. A pivot bearing is between an inner contour of the clamping sleeve and a shaft contour of the chisel shaft so that a center longitudinal axis of the round shaft chisel is pivotably seated with respect to a center longitudinal axis of the clamping sleeve. As a result of the induced tumbling motion of the round shaft chisel within the clamping sleeve 30, improved dirt removal can be assured during operations. The improved rolling action results in reduced wear between the clamping sleeve and the chisel shaft, which has advantageous results regarding the service life.

摘要： A cutting tool of a cutting machine having a base part and a bit holder. According to this invention, the bit holder has a plug-in attachment, retained in a socket of the base part that has a stop against which the bit holder rests. To prevent the penetration of water and stone dust and to allow the bit holder to be easily detached from the base part, a sealing element is located between the bit holder and the base part, surrounding at least sections of the socket.

The upper part has an opening for receiving a shank chisel and the base part has a shaft opening, into which a shaft of the upper part is inserted, and the shaft has a tensioning surface that rests against the counter surface of a clamping element. The clamping element has a tensioning screw which is used to clamp the tensioning surface against the counter surface. The base part has a shoulder surface, which is located in the vicinity of or near the shank opening and at least partially surrounds the shank opening. A stop surface adjoins the rear region of the shoulder surface in the infeed direction at an angle. The upper part rests on the stop surface by a supporting surface and is held at a distance, at least in sections, from the base part.
