Making a PVC Drill Bit

How to Make a Drill Bit from PVC Pipe

You can make a perfectly good drill bit from a piece of PVC with teeth or serrations cut into the end.  These teeth dig into the dirt (or clay or sand) and grind it up into small cuttings that can be washed to the surface.  The bit can be cut with a hacksaw or a file.  I like to do it with a bench grinder as it is quick and easy.  Below is a picture of one cut from a two inch piece of PVC with a bench grinder.  Click on the video to play it.

Here is an example of a bit cut with a hacksaw. Don't worry about the burrs. You can clean them up easily or they will come off very quickly as soon as you start drilling.
