Abstract
A tool-mounting assembly includes a tool head having a receiving bore and a basic tool holder having a receiving pin that is shaped for insertion into the bore. The bore has a groove with a sloping surface and the receiving pin includes movably mounted clamping elements having lugs. The assembly also includes a clamping device in the form of a screw with left-handed threads that engage one clamping element and right-handed threads that engage the other, so that the clamping elements can be moved away from each other to force the lugs into the groove and thereby clamp the tool head to the basic tool holder. In another embodiment an axially movable push rod is used as the clamping device to force the clamping elements away from each other.
