Abstract: The invention relates to a tool holder for elongate tools, in particular for drill bits, with two holder parts which are connected to one another in an articulated manner on one long side. The holder parts can be swung open or closed like a book. Each holder part has a rear wall, four side walls and an open front side. Receiving shafts for the tool which is to be received are provided in each holder part. The receiving shafts are formed by mutually parallel crosspieces which project forwards from the rear wall of the holder part. A flap extends transversely over the receiving shafts of the holder parts. This flap covers part of the open front side and part of each of the crosspieces 5. The flap, in its bottom region, is fixedly or releasably arranged with the holder part such that it can pivot. The flap, in its top region, is connected to the crosspieces 5 and/or the side walls of the holder part by a clamping or latching connection.
