If you want to get the best match with crossgrained plugs over counter-bored screw heads, cut the plugs from the same wood as the work piece. This usually means they are best cut on site, but it’s difficult to use a plug cutter in an electric drill held freehand, and most sites don’t have the luxury of a resident drill press.
You can, however, use a plug cutter in a hand-held drill in conjunction with the guide strip shown in the drawing. The hole in the guide corresponds to the outside dimension of the plug cutter. When clamped to the workpiece, the guide will keep the plug cutter from wandering or entering the work at an angle that is out of square with the work.
