HAND HELD DRILL GUIDE Abstract A guide for drilling dowel receiving bores in workpiece to be joined. The guide includes a main body having flat surfaces provided with pieces of frictional material such as aluminum oxide #40 grit, cloth back facilitating retention of the guide in place on a workpiece during drilling without clamping. An opening in the main body permits alignment of a drill receiving opening with a marking on the workpiece. The guide, in conjunction with a center punch, is locatable over a drilling sight in a workpiece without reference to a workpiece edge with additional frictional material contributing toward retention of the guide in place on a workpiece remote from a workpiece edge.
