Abstract
The present application relates to a cutting tool (2), in particular a boring bar (2) for machining holes (16) separated from each other in an axial direction (4) by a given spacing distance (a), comprising a main body (10) extending in an axial direction (4) with an axis of rotation (R) with at least one cutting element (12), as well as with a number of guide elements (14) for guiding the main body (10) within a guide hole (16A), wherein the guide elements (14) for the axis of rotation (R) are separated by a guide radius (r1), wherein viewed in a cross-section, the main body (10) is divided into a functional region (19) and an eccentric region (20), wherein the cutting elements (12) and the guide elements (14) are arranged distributed over the circumference of the main body (10) over an angular region (α) of less than 180°.
