We found a very interesting tool called the CNC Router which has the ability to cut and drill metal. It's not just for hobbyists as you can use it to make your own custom twist drills and can also make your own custom milling machine spindle for turning metal blanks into parts for your car, truck or motorcycle
Here is a video of how it works
The CNC Router is basically a small machine that uses a parallel axis system to move the cutting tool along with it. The main difference between this and an old fashioned table saw is that this one has an electronic control system that allows you to adjust the speed of the cutter head and make it move up or down depending on what part you are cutting.
