An additional cutting tool is mounted for radial adjustment on the spindle individually of the boring bar. The tools on the boring bar and the cutting tool on the spindle are adjusted radially by means of a helically splined nut engaged with a similarly splined shaft which is rotated relative to the spindle in response to axial displacement of the shaft.
