A drill head for creating a substantially vertical borehole in the ground, includes a body connected to a rotational drive of a drilling device; drilling tools on the body, for loosening the ground at a working face of the borehole; suctioning elements for leading away the loosened ground, which can be connected to a pump, and the suctioning elements include an opening region on the body and with at least one opening in the region of the drilling tools. The opening region has may have an elongate extent, and is connected to a suction box with an opening for connecting to the pump. The loosened ground can be sucked through the opening into the suction box with the pump. The suction box is tapered in width from the opening toward the connection opening, and that the height of the suction box increases from the opening toward the connection opening.
