A universal drill stand for supporting a hand-held drill in an elevated and inverted position for drilling holes or inserting fasteners into a concrete ceiling or other overhead surface. The universal drill stand is extendable for use with varying ceiling heights. It eliminates the need for a worker to construct scaffolding or ascend a ladder or other elevating device to drill each hole, allowing the worker to remain safely on the floor and away from dust and debris associated with the drilling.
