Cutting tool and method for machining a bearing tunnel

A cutting tool comprising a main part, which is capable of being rotationally driven about a rotational axis, at least first and second cutting insert holders arranged on the main part such that the first and second cutting insert holders are capable of being radially set, and a setting device for setting a position of the first and second cutting insert holders relative to the main part, wherein the first cutting insert holder is arranged in a first guide recess in the main part and the second cutting insert holder is arranged in a second guide recess in the main part, such that the first and second cutting insert holders are capable of being moved transversely to the rotational axis, and the setting device comprises a setting rod, which is arranged in the main part such that the setting rod is capable of being moved axially, and the setting rod supports the first and second cutting insert holders, and the setting rod is shaped such that axial displacement of the setting rod causes radial displacement of the first and second cutting insert holders,

• the cutting tool further comprises an adjusting device, which is integrated in the first cutting insert holder,
• the adjusting device comprises a setting element and a threaded drive, the setting element comprises a control slope that is supported on the setting rod, and
• rotating the threaded drive about a threaded drive axis displaces the setting element relative to the first cutting insert holder, thereby displacing the control slope transversely relative to the rotational axis and transversely relative to the setting rod, the threaded drive axis being offset from the rod, the control slope being shaped so that said displacing the control slope adjusts the position of the first cutting insert holder radially in relation to the setting rod.
