Abstract
The invention relates to a broaching tool, in particular a keyway broaching tool, comprising a holder which defines a longitudinal axis and has a shank, extending in the longitudinal direction, as support for a cutting body which can be fixed in a seat of the shank by means of a clamping device. 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. An end-position limit for the inserted cutting body is formed on guide surfaces and on associated bearing surfaces. The clamping device produces a force component on the cutting body which presses the latter against the end-position limit.
