The tool-holder with lateral locking locates a milling bit or a drill bit on a drive shaft of a machine tool and may house onto a cylindrical tool shank (31'). Radial deflections of the holder and thus decentering of the bit is avoided by housing the holder in a sleeve (5). The walls of the sleeve are tapped (51) to receive the locking screw (52) and provide resistance to locking forces, an aligned clearance hole in the holder wall allowing the screw to penetrate into a shank groove (311'). Two screws may be provided at intervals on the shank axis, at intervals on a sleeve circumference, or offset in both directions.
