The invention relates to a drilling bucket and a method for producing a bore with a drilling bucket, wherein the drilling bucket is driven in a rotating manner and introduced into the ground, wherein ground material is removed and received in an internal space of a tubular base body of the drilling bucket, and for emptying the drilling bucket is withdrawn from the bore and a bottom on the tubular base body is folded open. According to the invention the drilling bucket is rotated in a reversing manner during emptying, wherein ground material received in the drilling bucket is pressed against at least one impact wall and, in doing so, the ground material is specifically compacted and deformed for easier loosening from the internal space.

The invention relates to a ground processing tool and a method for creating a borehole in the ground, wherein ground material is removed by the ground processing tool and blended with a fluid in the created borehole to form a suspension, which is suctioned away via at least one opening in the at least one mixing blade and via the conducting channel in the central shaft.

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.
