Abstract
A rotary tool includes a tool holder, a reversible bit, and an outer rotatable sleeve. The tool holder includes a socket and a shank. The socket includes an opening extending rearwardly from an end thereof. The shank is integral with and extends rearwardly from the socket and includes a non-circular cross-section. The reversible bit includes an inner sleeve, a first reversible bit driver, and a second reversible bit driver. The inner sleeve is disposed within the socket and rotates with the tool holder. One of the first and second bit drivers extends axially out of the socket opening. The outer rotatable sleeve is disposed over at least a portion of the socket and the bit driver extending axially out of the socket opening. The outer rotatable sleeve further includes a magnet in an end proximate the bit driver extending axially out of the socket opening.
