Multi-bit screwdrivers come with multiple tip sizes and styles that attach to one handle and allow a single tool to loosen and tighten a variety of screw sizes. They avoid the need to carry a bulky set of screwdrivers with handles. Multi-bit models have a handle attached to a shaft with a tip that is inserted into shaft. The tip is inserted into the indentation in the screwhead and the handle is turned to rotate the screw. Some models allow extra bits to be stored in the handle to ease access to bits and avoid loss.
