Abstract: A drill bit that serves to remove mineral materials and that consecutively has on a longitudinal axis (6) a drill head (2), a helix (3), an insertion end (4) and an impact surface (7) on the end face of the insertion end (4) that faces away from the drill head (2) and that serves to absorb impact along a direction of impact (8), is provided. The drill head (2) has at least two cutting edges (13) and at least two blades (20). The cutting edges (13) each have a cutting face (16) and a free face (17). The blades (20) run parallel to the longitudinal axis (6) and adjoin the cutting edges (13). The blades (20) each have a radially projecting tooth (24) that adjoins the cutting face (16), whereas it adjoins the free face (17) either only partially or not at all. The axial dimension (29) of the tooth (24) is smaller than the axial dimension (25) of the blade (20).

Abstract: The setting tool (1) has a first part (2) for driving in a drop-in anchor and a second part (3), placeable on the first part along an axis (8), for drilling a drill hole for the drop-in anchor. The first part (2) has an insertion end (5) for a percussive portable power tool, a plunger (6) having an impact surface (12) and a piece (16) of a rotary coupling. The second part (3) has a slip-on sleeve (20), which coaxially surrounds the plunger (6) and bears against the impact surface (12) of the plunger (6), a counterpart (33) for the rotary coupling and a drill bit (23) permanently connected to the slip-on sleeve (20).

Abstract: 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.

Abstract: A drill head extending along a drill axis made of hard metal for rock drills is disclosed. The drill head features at least one major cutting edge and at least one minor cutting edge, where the major cutting edge extends from a first radially inner end to a first radial outer end which lies on a first diameter and where the minor cutting edge extends from a second radially inner end to a second radially outer end which lies on a second diameter that is smaller than the first diameter. A first enveloping surface defined by the minor cutting edge projects completely axially over a second enveloping surface defined by the major cutting edge.
