Abstract

A boring tool for the fine finishing of surfaces of holes having at least one cutting bit and at least one guide ledge which are introduced and fixed in place in grooves arranged in the circumferential surface of the base body of the boring tool, characterized by the fact that a setting device is provided which is positively coupled with at least two cutting bits associated with each other; that the cutting bits are arranged displaceable by means of the setting device in the base body with respect to the circumferential surface; that the association of the cutting bits consists in that they are displaceable in opposite directions, with respect to the axis of rotation or center line of the boring tool; and that the setting device in each case displaces one cutting bit into a working position and the other cutting bit into a position of rest.
