A cutting tool has a shank with a circumferential groove and an adjustment ring releasably secured to the shank at the groove. The adjustment ring has a threaded through bore in which a screw is screw mounted and engages the groove. The adjustment ring has an adjustment member which engages the groove and which is positioned diametrically opposite the threaded through bore. When the screw is tightened it exert a purely radially directed force on the groove thereby inducing displacement of the adjustment member radially inwardly and the adjustment member exerts non-radially directed forces on the groove, thereby inducing a bending moment on the shank for correction of radial runout.
