Abstract
A boring and milling tool for machining of metal workpieces includes an essentially cylindrical, elongated basic milling body, with at least one chip removal groove machined into its circumference, penetrating the face end of the boring and milling tool. A pocket is provided in this chip removal groove for an indexable cutter bit insert (16) retained therein. One cutting edge (24, 26) of the insert operates circumferentially, and another cutting edge (25, 27) operates at the face end with respect to the boring and milling tool. To prevent the production of long chips at the end cutting edge (25, 27) of the insert (16) during boring operations with the boring and milling tool, the insert (16) here has a different cutting edge geometry than at the cutting edge (24, 26) that is effective during milling.
