Abstract: The invention relates to an article hanger having a receiving region, wherein, by means of the receiving region, a receiving space for receiving an article of at least one article type, for example at least one type of tool for a mobile machine tool or at least one type of building product, is formed in the interior of the receiving space. The receiving region is formed from a wound tube and/or comprises a wound tube. An environmentally friendly material can be used as the raw material for the wound tube. Risks to the environment as a result of carelessly discarded article hangers can therefore be avoided or at least reduced.

Abstract: A method for producing a drill shaft for a wet drill bit includes forming N, where N?1, strip materials into a tubular body where the tubular body is integrally joined at strip edges of the strip materials by N connection welds. At least one strip material of the strip materials is provided with at least one recess before the integral joining of the strip edges.

Abstract: A drill bit includes a drill bit head, a multi-strand helix made up of three or more helix ribs, and a shank end along a drill bit axis. The multi-strand helix is made up of a conveyance area, a helix gradient, and a pitch. The helix ribs extend parallel to the drill bit axis in a first area adjacent to the drill bit head and a second area adjacent to the shank end.

Abstract: A method for producing a cutting section from a closed tubular element (14) which is in the form of a hollow cylinder and from one or more drill segments (16) which are connected to the closed tubular element (14).

Abstract: A cutting section (11) which is connectable to a drill shaft section via a releasable connecting device. The cutting section includes a first open tubular element (14) which is in the form of a first hollow cylinder having a first waved, trapezoidal or zigzag-shaped cross-sectional area, a second closed tubular element (15) which is in the form of a second hollow cylinder having a circular ring-shaped cross-sectional area, and one or more drill segments (16) which are connected to the first open tubular element (14) and to the second closed tubular element (15).

Abstract: A method for producing a drill includes cold forming of a rod-shaped blank to form a semifinished product having three or more rectilinear longitudinal ribs extending along a longitudinal axis of the semifinished product, introducing the longitudinal ribs into a first die and a second die in a working direction, where the first die bears against the longitudinal ribs in a direction of rotation about the longitudinal axis and the second die bears against the longitudinal ribs counter to the direction of rotation, pivoting the first die in the direction of rotation in relation to the second die in order to twist the longitudinal ribs between the first and second dies, pulling the longitudinal ribs 31 through the pivoted first die and the second die counter to the working direction in order to twist the longitudinal ribs and apply a drill head to the rear end in the working direction.

Abstract: A drill bit has, along a drill bit axis, a drilling head, a multi-start helix made of two or more helical coils, and an insertion end. The helix has a helix slope and a pitch in a delivery region. In an outlet region of the helix, the outlet region being directed towards the insertion end, the helical coils merge continuously, within a first portion, from an orientation in alignment with the helix slope into an orientation parallel to the drill bit axis. A length of the first portion is at least one quarter of the pitch of the delivery region. The helical coils, in a second portion, are oriented parallel to the drill bit axis.
