Abstract
A milling tool for machining cylindrical sections of crankshafts comprises a rotatable tool drum adapted to be mounted so that it surrounds the workpiece and to be driven and which at one end carries an internally cutting, annular primary cutter head and adjacent thereto is formed in its shell with apertures for the removal of chips. An internally cutting, annular supplemental cutter head has axially projecting claws and is detachably but rigidly secured to the primary cutter head and is axially supported against the latter by the claws. In such tool, a satisfactory removal of chips is ensured, and the supplemental cutter head can be simply and quickly removed to convert the multiple cutter tool to a single cutter tool.
