A boring tool has a slider member connected to a cutting insert seat, the slider member is arranged movably inside a tool body of the boring tool along a path extending transversely to a rotation axis of the boring tool for adjusting the distance of the of the cutting insert seat in relation to the rotation axis. A wedge-shaped clamping member is connected to a drive unit and arranged inside the tool body. The wedge-shaped clamping member is in contact with the slider member for clamping the slider member into a locked position, in which locked position, the wedge-shaped clamping member is pre-loaded to passively lock the slider member. The drive unit is controllable such that the wedge-shaped clamping member is actively releasable when adjusting the distance of the cutting insert seat.
