Abstract:
1. A combination tool for use in machine tools for the machining of workpieces comprising a base body with several reaming blades for reaming a cylindrical bore, which reaming blades are distributively arranged over the circumference of the base body, and have a chamfer and a guide surface, the combination tool further comprising at least one grooving blade arranged axially displaced on the base body with respect to the reaming blades, and controllable radially with respect to the base body, wherein two guide strips are arranged at an angular distance from one another between two circumferentially mutually adjacent reaming blades in the base body, and are displaced axially with respect to the reaming blades in direction of the grooving blade, the guide strips have the same flight-circle radius as the reaming blades, and provide support during a grooving operation at an angular distance on opposite sides of a cuttingforce resultant of the at least one grooving blade within a bore.
