A tool holder for an automatic screw machine includes and L-shaped base portion with one leg secured to the machine's axially reciprocable tool support fixture, and includes an upstanding leg or web which carries an elongated cutting tool oriented parallel to the axis of the machine. A second tool is also provided on the upstanding web, and in one version is oriented perpendicularly with respect to the first tool for cutting cup-shaped workpieces, and in another version is oriented parallel to said first tool, both versions being particularly suited to machining cup-shaped workpieces.
