How can I use a plug cutter to fix a hole in a cabinet door?

A plug cutter is a circular drill bit that cuts clean holes into any wooden object. The holes a plug cutter makes are tapered, which allows you to create a perfectly fit plug for your cabinet door. The way you fix a door with a plug cutter is to cut a hole in the door using your plug cutter. Then use the same plug cutter in a different piece of wood to create the plug for the cabinet door hole. Line the inside of the cabinet door hole with glue and then insert the plug into the hole. Allow it to dry, sand it smooth and then paint or stain the door to finish.
