    摘要: A drill bit 1 has a drill head 3 and a shank 4. The shank 4 has a body 20, an add-on part 40 and an internal channel 50. The drill head 3 is attached to the body 20. The add-on part 40 is attached to a lateral surface 21 of the body 20 and arranged completely within a cylindrical envelope 29 that circumscribes the body 20. The internal channel is configured within the add-on part and/or between the add-on part 40 and the lateral surface 21.

    摘要: A production process is provided for a drill including the following steps. From a rod-shaped blank comprising an end section, a central section, and a hollow space extending at least through the end section and the central section along an axis of the blank, the end section is formed in a direction extending radially relative to the axis, the diameter of the hollow space in the end section being reduced. Either a cutting element is attached to the end section or grooves are introduced into the end section for forming a shank.

    摘要: A method of anchoring a fastening element includes drilling a borehole (7) in a constructional component (6) with a percussively-rotationally driven hollow drill (12), while aspirating produced drillings and drilling dust with a vacuum source (26) through a gap between an outer side of the hollow drill (12) and a wall of the borehole (7) during drilling of the borehole (7), immediately after formation of the suction-cleaned borehole (7), filling the borehole (7) with a self-hardenable mortar (41), and inserting the fastening element (46) into the self-hardenable mortar (41).
