Abstract
The case for drill bits or the like provides automatic rotation a holder to an access position on opening the cover, without any linkage to the cover. The rotation may be by virtue of a molded or mechanical spring or other biasing means, such as springiness of a living hinge, for example. Each holder provides multiple holes into or through which drill bits or the like are inserted. The action of closing the cover moves the holders from their access position into a storage position, by contacting one or more of the holders, or one or more of the drill bits. The case can be a one-piece molded construction, or an assembly of various components, e.g. base, cover, holders, and removable stop walls. A locking bar may be provided to prevent removal of drill bits of the type having a recess in their shanks, and the locking bar may be movable between a locked and unlocked position, for example by closing or opening of the cover.
