Drilling Square Holes

[Larry Frank]

I found this faciniating that you could "drill" a square hole. The cutting tool goes around like a drill bit and the tool moves as it cuts. I think that it might be too expensive for wood working.

The process is called wobble broaching and has been around for a little while now. Can drill blind holes with as many facets as you like: http://youtu.be/zZpWcl1BKVk

Might not work too well in wood. It scrapes a bit coming out of the corner.
