Tool, tool insert and group of tools

A group of tools, each tool comprising

• a) a tool insert with a revolver which can be rotated about a rotational axis and comprises a first pair of processing bodies and a second pair of processing bodies, the processing bodies of each pair
• aa) together forming an accommodation for a workpiece, the accommodation comprising a longitudinal axis and
• ab) being movable during a processing stroke along a processing axis relative to each other and radially to the longitudinal axis from an open relative position into a closed relative position, such that a workpiece is processed between the processing bodies of the respective pair of processing bodies,
• one of the processing bodies of each pair of processing bodies having an actuating surface and the processing axes of the first and second pair of processing bodies being oriented in different directions radially to the rotational axis relative to the revolver,
• b) a tool actuating unit comprising an accommodation for the tool insert and an actuating plunger having an actuating surface,
• c) wherein the revolver and the processing bodies of the first and second pair of processing bodies can be rotated together about the rotational axis from a first rotational position into a second rotational position and
• d) in the first rotational position of the revolver the actuating surface of the actuating plunger of the tool actuating unit actuates the actuating surface of the one processing body of the first pair of processing bodies and in the second rotational position of the revolver the actuating surface of the actuating plunger of the tool actuating unit actuates the actuating surface of the one processing body of the second pair of processing bodies,
• wherein the group of tools comprises a first subgroup and a second subgroup, wherein the tools of the first subgroup and the tools of the second subgroup comprise different types of tool actuating units, but the same tool inserts.
