ABSTRACT:
A composite tool unit comprising a tool shank, a tool head a chuck, a drawbar which is slidable in the longitudinal direction of the tool shank and a pulling shank which projects from the tool head. The drawbar and pulling shank are engaged around by the chuck, which is disposed in the tool shank axially to slide between an opening position and a closure position. The tool shank comprises an inner conical face which tapers in the direction of the drawbar and co-operates with outer conical segments disposed on the clamping jaws. The zones of the drawbar 8 and pulling shank 8 of the tool head engaged around by the chuck have respective projections. The flank of the radial projection of the drawbar which is remote from the tool head registers in each position of the clamping jaws with radially inwardly extending projections thereof to transmit an axial pull to the clamping jaws, whereas the projection of the pulling shank in relation to the clamping jaw projections registers only in the closure position of the chuck. The tool head is pulled via the drawbar, the chuck and the pulling shank into a positive connection (Hirth-type serrations) with the tool shank.
