Zusammenfassung:The invention concerns a drill bit for percussion drilling or impact drilling use for cutting reinforcing steel in concrete, wherein the drill bit has a substantially hollow-cylindrical carrier body extending along a geometric drill bit axis, wherein the carrier body has at least one chisel tooth with a substantially radially extending first chisel edge. It is proposed that the first chisel edge is arranged in a middle portion of the chisel tooth, in particular precisely centrally, in the circumferential direction, and the chisel tooth has a second chisel edge extending substantially tangentially to the circumferential direction of the drill bit.
