A portable drill support having a force transfer assembly that comprises a pair of parallel linear segments joined in a hinged manner that allows the relative position of the segments to be varied while still maintaining their parallel relationship. The segments are joined by a pivoting swing hinge member and a pivoting handle member, the handle member being the leveraging arm used to apply force to the drill. The force assembly is joined to either an extension assembly, preferably composed of detachable extension segments, or a forward bracing assembly that comprises a hook member. Preferably the drill mount, the extension assembly and the forward bracing assembly are connected by mechanical interlocking means that allow the apparatus to be disassembled.
