Abstract:
1. A broaching tool comprising: a cutting body; a holder which defines a longitudinal axis and has a shank, extending in the longitudinal direction, as support for the cutting body; a clamping device for fixing the cutting body in a seat of the shank; wherein the seat has a passage which is at a distance from the free end of the shank and extends transversely to the longitudinal axis and the inside of which forms guide surfaces for bearing surfaces of the cutting body, which can be inserted into the passage in an insertion direction, wherein an end-position limit for the inserted cutting body is formed on guide surfaces and on associated bearing surfaces, and wherein the clamping device produces a force component on the cutting body which presses the latter against the end-position limit, wherein to form the end-position limit, at least one surface part projecting from a bearing surface is provided on the cutting body, said surface part forming a stop surface which, when the cutting body is inserted, comes to bear against a step, forming a counter-stop, of a guide surface of the passage.
