The tool comprises a cylindrical cartridge (10, 10') having a longitudinal or angled bore (1) therein and a second bore (2) transverse thereto with a tool shank (50) carrying a tool tip (51) slidable within it. A rotatable control knob (43) rotates a micrometric screw (30) in the bore (1) which extends through an axial bore in a toothed segment (20) and is screw threaded into a bushing (24). Rotation of the screw causes axial movement of said toothed segment. Angled teeth (22) on the toothed segment engage with corresponding teeth (52) on the tool shank to move the shank transversely. Both the screw (30) and the segment have backlash preventing means. <IMAGE> |
