Tool head for use in machine tools

A tool head for use in machine tools, comprising a base body, a tool shank adapted to be coupled to a machine spindle and protruding axially over the base body, at least one working slide adapted to be displaced essentially transversely with respect to a base body axis and having a tool holding fixture protruding over a front face thereof, and an adjusting motor disposed in the base body and acting on the working slide in a direction of displacement by means of a transmission means, wherein the transmission means comprises an output shaft adapted to be rotated concentrically with respect to the base body axis, the output shaft carrying a drive sprocket which meshes with toothing on a side of the working slide, wherein the toothing on the side of the working slide is disposed on an intermediate transmission element which is linearly guided in the base body, the intermediate transmission element being coupled to the working slide by a wedge gear or an intermediate gearwheel.
