Drilling head for a percussive displacement ground drilling device and use of a drilling head for a percussive displacement ground drilling device

Drilling head for a percussive displacement ground drilling device with a first and a second drilling head section, the first drilling head section having discharge ducts and the second drilling head section having a cross section that increases in a longitudinal direction, wherein the second drilling head section includes a plurality of step-shaped areas,

• wherein the step-shaped areas are configured without cutting edges in a circumferential direction and/or in a radial direction, wherein each of the step-shaped areas have a step height, wherein the step height is an increase in a radius of the second drilling head section provided by the step, and wherein each step height is between about 4% and 15% of a diameter of a housing of the ground drilling device,
• wherein the first drilling head section is arranged in front of the second drilling head section in an advancing or forward direction;
• of the ground drilling device,
• wherein the plurality of step-shaped areas are located behind the discharge ducts of the first drilling head section, such that the plurality of step-shaped areas engage drill cuttings diverted through the discharge ducts, wherein the engaged drill cuttings are deflected and pressed into a wall of a borehole.
