Claim 0:
1. A boring tool comprising:
a tool body including a front end and a rear end, between which a central rotation axis extends around which the tool body is rotatable in a direction of rotation;
a slider member connected to a cutting insert seat, wherein the slider member is arranged movably inside the tool body along a path extending transversely to said the rotation axis for adjusting a distance of the of the cutting insert seat in relation to the rotation axis; and
a wedge-shaped clamping member connected to a drive unit, the wedge-shaped clamping member being arranged along an extension axis and movable along the extension axis inside the tool body and 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 by means of a biasing spring to passively lock the slider member, the drive unit being controllable such that the wedge-shaped clamping member is actively releasable when adjusting the distance of the cutting insert seat in relation to the rotation axis, wherein the wedge-shaped clamping member includes a threaded recess portion in a cavity of the wedge-shaped clamping member, the cavity extending along the extension axis, wherein a threaded bolt is received within the cavity, and wherein the threaded bolt, when rotated in a first direction, causes the biasing spring to compress by moving the wedge-shaped clamping member against the biasing force of the biasing spring to release the locked position of the wedge-shaped clamping member, and the threaded bolt, when rotated in a second direction, forces the wedge-shaped clamping member into clamping engagement with the slider member.
