A power drill accessory for use with a power drill for guiding a drill bit, comprises a body including a rack (2) which releasably holds drill bit guide members (5) in separate compartments, each guide member including an bore dimensioned to receive a drill bit of an appropriate diameter, the body having a head region (1, 4) which releasably holds a selected guide member in a position for guiding a drill bit held in a power drill, and a handle member (3) for gripping in one hand, which extends over the rack and which is joined at one end, at the head region, to the rack. The lower surface of the head region, partly defined by the lower surface of the selected guide member, provides an extended grip surface area for gripping against a work surface. The lower surface of the guide member has channels for exhausting drill waste material. |
