Zusammenfassung: | The boring tool has an insert upon which one or two boring heads are slidably guided along a swallowtail track. For fixing the boring heads in position, set screws are provided which are adapted to bear against the clamping surfaces of the insert. To preclude radial sliding of the boring heads, even when the set screws are only partially tightened, the clamping surfaces are inclined relative to the longitudinal axis of the insert, and the spacing of the clamping surfaces from the longitudinal axis increases toward the ends of the insert. |
