    Abstract: A hand grip of a screwdriver for bits has a grip member having a first end and a second end. The first end has a tool holder for the bits. The second end has a stationary core with a round magazine having bit compartments extending in the longitudinal direction of the grip member and a closure device rotatable relative to the round magazine. The closure device has a sleeve providing an ergonomic outer shape of the second end of the grip member. The sleeve is rotatably supported on the stationary core and has a longitudinal access opening which passes externally across the bit compartments when the sleeve is rotated relative to the stationary core. The access opening can be aligned with the bit compartments for removal or insertion of the bit. The sleeve has a longitudinal length such that the upper end and the lower end form a closed ring, respectively.
