Abstract
The invention relates to a drilling tool for earth drilling with a drill rod element which can be connected to a rotary drive and can be driven in a rotating manner about a drilling axis, a frame-like housing and at least one removal tooth which is supported in a radially adjustable manner in the housing between a retracted position in the housing and an operating position, in which the at least one removal tooth projects radially from the housing. Furthermore, on the drill rod element in the housing a transmission mechanism is arranged, through which a stroke and/or rotational movement of the drill rod element can be translated into a radial movement for radial adjustment of the at least one removal tooth.
