US 9,314,852 B2 · Right angle attachment for power tools

Abstract

A right angle attachment for use with a power tool that includes a housing having a handle portion and a gear case attached to the handle portion and supporting first and second right angle gears wherein the first right angle gear is driven by an input shaft that is connected to the drill and the second right angle gear has an opening therein for receiving a hex bit directly therein. A floating magnet head can surround the hex bit to aid in fastener retention and can be movable out of proximity of the hex bit to facilitate easy removal of the hex bit for replacement. An additional magnet can be disposed within the gear case at the base of the hex bit in order to magnetize the hex bit and further enhance the retention of the fastener therein.
