  • Patent number: 11911834
    Abstract: A drilling tool for producing a bore with a cylindrical inner wall can be rotatable in a rotary movement with a predetermined rotational direction (VD) about a tool axis (A) extending through the drilling tool, and at the same time is movable in an axial forward movement (VB) in a forward direction axially to the tool axis. The drilling tool comprises at least one drilling area (3) arranged in a forwardly located region of the drilling tool at a forward or free end, but preferably not having a thread forming region. The drilling area has a number n of drilling edges which are arranged offset to each other in the rotational direction, and at least one chip divider is arranged on at least one or each of the n drill cutting edges, where the chip divider forms an interruption of the respective drill cutting edge.

  • Publication number: 20220331894
    Abstract: In a method for creating a through-thread, thread creation means is moved in a screw-in movement in an axial forward direction (VR) through a workpiece from a first workpiece side to a second workpiece side opposite the first workpiece side such that the end face projects out of the workpiece, wherein the thread creation means is moved through the workpiece, in particular along a first line which is a helical line, wherein then, to create at least one countersink, the thread creation means is moved in a countersinking movement, in particular along a second line that differs from the first line, and wherein, for subsequent withdrawal, the thread creation means is moved back through the workpiece in a screw-out movement in the axial backward direction (RR), in particular at least substantially along the first line.

  • Publication number: 20220184723
    Abstract: A tool for generating a threaded hole is rotatable in a rotational movement about a tool axis extending through the tool, and is movable in an axial forward direction axially of the tool axis. The tool comprises at least one thread generation area and at least one drilling area, which are rigidly motion-coupled to each other. The drilling area is provided for generating a core hole and is arranged axially offset to the tool axis with respect to the thread generation area. The thread generation area projects radially to the tool axis, runs along a helical line, and a predetermined winding sense of the thread to be generated, and has a working profile which corresponds to the thread profile of the thread to be generated. The drilling area has a drilling edge, and at least one chip divider is arranged on the drilling edge, interrupts the drilling edge.
