摘要： An improved cordless motor-driven electric hand tool that has an elongated body portion with a tool bit-receiving chamber at one end and a housing at the other end having a battery-receiving chamber therein. An elongated tool bit storage chamber is formed in the housing above and/or below the battery-receiving chamber and has a cover that is pivotally mounted for open and closed positions. The housing is oval shaped to create a space above and/or below the battery-receiving chamber in which the tool bit storage chamber is formed.
