Boring tool

A boring tool comprising

• a tool body including a front end and a rear end, between which a central rotation axis extends around and which the tool body is rotatable in a direction of rotation;
• a slider member arranged movably inside the tool body along a path extending transversely to said central rotation axis;
• an insert pocket associated with the slider member to move therewith and configured to receive a cutting insert to be secured therein by a fastening member, which cutting insert has a cutting edge that projects from the tool body transversely to said central rotation axis;
• a motor member connected to the slider member and controllable to move the slider member transversely to said central rotation axis for changing a distance between the cutting edge of the cutting insert and said central rotation axis and by this distance the radius to be created in a hole of a workpiece when bored by rotation of the tool body;
• and
• a control unit configured to control the motor member to move the slider member, wherein the motor member is arranged inside the tool body together with the slider member in a cutting part of the tool body at said front end, and that the motor member is arranged in parallel with said transversal extension of the slider member along said path.
