Abstract:
A tool for machining bores which are centered on a bore axis extending along a workpiece, a tool having:a base body having a tool axis and insertable in the workpiece in an eccentric insertion position such that the tool axis is radially offset from the bore axis during subsequent axial displacement of the base body toward a predetermined axial position; a plurality of axially spaced apart cutters projecting from the base body for machining the bores in the workpiece; the base body having at least one integrated lifting element displaceable axially with the base body to the predetermined axial position in which the at least one integrated lifting element acts upon the base body so that the base body can be moved from the eccentric insertion position into a central machining position, in which the tool axis coincides with the bore axis of the bores, whereby relative rotation of the tool and the workpiece in the central machining position causes the cutters to machine the bores.
