Screwdriver handle has a storage chamber for screwdriver bits, the storage chamber being displaceable from a closed position into an open position by axial displacement of two parts of the handle with respect to one another. One handle part has a core, which is disposed in a cavity in the other handle part. The two handle parts are held in the closed position of the storage chamber by latching means movable out of a latching position by pressure on an actuating zone () associated with an end side of the handle.

A clamping chuck comprising a shank which has two sleeve-like shank sections ( ), one of the sleeve-like sections ( ) on an end side thereof being coordinated to a clamping section ( ) for clamping into a drive member, and the other of the sleeve-like sections ( ) on its end side being coordinated to a toolholder ( ) for mounting a tool, in particular a screwdriver bit ( ). The two sleeve-like shank sections ( ), by a torsion section ( ) formed by a torsion member ( ) coordinated to cavities of the shank sections, being twistable with respect to one another about a stop-limited angular distance (a-b), wherein the torsion section ( ) is arranged between two hexagon sections of the torsion member ( ), by which hexagon sections the torsion member is fitted without play into hexagon profile sections in the cavities ( ) of the sleeve-like shank sections ( ), and the torsion member continues, as one material integral piece into the clamping section formed as an insertion section ( ).
