Abstract
A drilling tool comprising a tool holder that extends along a central axis and comprises a first cutting insert receptacle having a first abutment surface oriented parallel to the central axis. The drilling tool further comprises a first cutting insert that is fixed in the first cutting insert receptacle and abuts with one of its sides against the first abutment surface, wherein an axial portion of the first cutting insert projects axially beyond an end face end of the tool holder, and wherein the first cutting insert comprises in the axial portion a first main cutting edge that is inclined with respect to a first imaginary plane, which is oriented orthogonally to the central axis and arranged at the end face end of the tool holder, so that a radially outer end of the first main cutting edge is spaced a larger distance from the first imaginary plane than a radially inner end of the first main cutting edge and the first main cutting edge does not intersect the first imaginary plane, and wherein the first main cutting edge touches or intersects a second imaginary plane that is spanned by the central axis and oriented orthogonally to the first abutment surface.
