Abstract
An insulating hand tool has an elongated shank injection molded of a high-strength, electrically insulating material, such as glass-reinforced nylon, and a handle formed of an electrically insulating material. The handle and the shank may be molded together in a unitary, one-piece construction, or the handle end of the shank may be press-fitted in an axial bore in one end of the handle or the shank may be insert molded into the handle. The working end of the shank is adapted to carry a working tip or a socket, either of which may be insert molded in the working end of the shank or may be press-fitted in an axial bore therein. The socket may form a nut driver or define a receptacle to removably receive a working tip. The working tip may be a commercially-available, double-ended bit, with a Phillips tip at one end embedded in the shank.
