Abstract
A simple and inexpensive hand-held drill bit guide that can be conveniently used with electrically powered hand-held drills to provide a precisely perpendicular orientation angle with respect to the surface of an article to be drilled, wherein the surface may be flat, cornered or otherwise generally non-planar, e.g. convex, concave, cylindrical, etc. The drill bit guide has first and second guidance members, wherein a guidance hole communicates therewith in perpendicular relation thereto for guiding a bit inserted thereinto with respect to a surface of an article interfaced with one of the first and second guidance members such that always the guidance hole will be oriented perpendicularly with respect to the surface.
