A rotatable tool handle device includes a handle having a chamber for receiving a spring biased latch, a shank having one end rotatably secured to the handle with a pivot shaft and having a number of cavities. A latch is slidably engaged in the chamber of the handle, and guided to move relative to the handle, and has a tongue for solidly engaging into the either of the cavities of the shank and for securing the shank to the handle at a selected angular position. A spring may bias the tongue of the latch to solidly engage with either of the cavities of the shank.
