A tool bit case includes a first housing member and a second housing member pivotally coupled together. Each housing member includes a base and sidewalls extending from the base. The tool bit case also includes a plurality of retainers located along opposing sidewalls of the first housing member. The tool bit case further includes a modular tool bit holder that is engageable with a corresponding pair of retainers of the plurality of retainers. The modular tool bit holder is pivotable relative to the first housing member between a storage position and an upright position. When the modular tool bit holder is in the storage position, the modular tool bit holder blocks access to at least one retainer adjacent the corresponding pair of retainers, and when the modular tool bit holder is in the upright position, the at least one retainer is accessible.
