Abstract
The invention relates to a tool holder for use in machine tools, comprising a main body, which can rotate about an axis of rotation, and cutter holders which each hold a cutting plate and can be radially adjusted by means of an axially displaceable control rod and coupling means. In order to further develop said tool holder so that it is possible, within a very short time, to produce a turned groove which satisfies stringent demands regarding surface quality and geometric roundness, it is proposed, according to the invention, that the tool holder has at least two cutter holders which can be radially adjusted between a retracted position and an extended position and whose cutters can be simultaneously brought into engagement with the workpiece in order to produce a turned groove.
