摘要： A drill assembly including a drill and depth stop assembly is disclosed. The drill includes a housing, an electric motor and a chuck operatively driven by the electric motor about a drill axis. The depth stop assembly includes a depth stop rod, a mounting block, a fastener and a rotatable handle. The mounting block has a mounting surface adapted to cooperate with the housing, a first aperture spaced from the mounting surface for supporting the depth stop rod generally parallel to the drill axis, and a second aperture extending about a fastener axis generally normal the mounting surface. The fastener extends through the mounting block second aperture about the fastener axis and has two ends respectively cooperative with the housing and the handle to releasably entrap the mounting block therebetween to enable a user to adjustably position the depth stop rod relative to the housing. Preferably the fastener threadedly attaches to a threaded aperture in the drill housing. Ideally, the mounting block includes first and second mounting block halves which releasably clamp about the depth stop rod.
