摘要： The invention relates to a tool holder for a road milling machine or similar, comprising a base part, on which a tool shank and a collar are formed, the collar having a tool receiving opening and said opening being formed from a bush-type insert consisting of a hard material. In a tool holder of this type, in order to promote good rotational behaviour of the tool and guarantee support for the latter without the need for numerous parts, the tool receiving opening is designed as a stepped bore that has a first and a second diameter region, the first diameter region having a greater inner diameter than the second diameter region.

摘要： The invention relates to a tool system comprising a tool holder and a shank tool, the tool holder having a tool receiving opening with a first and a second diameter region which lead into one another via a transition section (narrowing) and a tool shank of the shank tool has a first and a second cross-sectional region which lead into one another via a transition section. To achieve a design for a tool system of this type that is optimised in terms of wear, the transition sections of the shank tool and the tool holder are interspaced in the direction of the central longitudinal axis of the shank tool to form a repositioning area.

摘要： The invention relates to a shank-type pick for a road milling machine or the like, having a pick head and a pick shank, wherein the pick shank has a first cylindrical section which indirectly or directly adjoins the pick head, and wherein the pick shank has a second cylindrical section which is remote from the pick head and indirectly or directly adjoins the first cylindrical section, and wherein the diameter of the second cylindrical section differs from the diameter of the first cylindrical section. With such a shank-type pick, improved use properties arise in that the first cylindrical section has a diameter in the range between 18 mm and 30 mm and an extent in the direction of the centre longitudinal axis of the pick shank of less than 30 mm.

摘要： The invention relates to a shank chisel (10) with a chisel head (12) and a chisel shank (16), wherein the chisel shank (16) has a securing element retainer (181) in which a securing element (40) is arranged. In order to enable a simple installation of the shank chisel (10) in a chisel holder (30) in a safe and maintenance-optimized operating mode, according to the invention, a tensioning element (20) can be displaced relative to the chisel shank (16) in such a way that at least one part of the outer contour of the securing element (40) is changed. The invention further relates to a corresponding fixing assembly (1) for a shank chisel (10) in a chisel holder (30).
