Abstract
The invention relates to a drilling tool for producing a bore in the ground, comprising a rotatably drivable basic body, a removal means at a lower end of the basic body for removing soil material, and at least one adjustable removal element, which is adjustable between a radially inner retraction position and a radially outer extension position in which the removal element protrudes radially outwards relative to the basic body in order to widen a bore diameter. According to the invention it is provided that for adjusting the removal element, an adjustment mechanism with a rotary member is provided, which is rotatable on the basic body about the drilling axis between a first rotary position and second rotary position, that at least one removal element is arranged on a pivot arm which is pivotable relative to the basic body between a first pivot position, in which the at least one removal element is in its retraction position, and a second pivot position, in which the at least one removal element is in its extension position, and that an actuating cam is provided on the rotary member and/or on the at least one pivot arm, by means of which actuating cam a rotary movement of the rotary member can be converted into a pivot movement of the at least one pivot arm.
