With a 16° taper, the same as a standard crank-type pencil sharpener, this reaming bit lets you easily restore stripped screw holes.
Used in a hand drill, it reams the hole, which you then plug with a dowel (or scrap of wood) sharpened in your pencil sharpener. The plug matches the hole perfectly every time. It works equally well preparing holes for decorative plugging.
By adjusting the depth control on a drill press, you can ream to whatever size you want, letting you easily make holes for plugs of any size up to 3/8" diameter. Plugs are almost costless since they can be made quickly in a pencil sharpener from shop scraps.
For restoring screw holes, instead of drilling a pilot hole in the center of a dowel, use one of the included 10 pre-drilled dowels (leadless pencils).
