One of the most unusual things you can do on a CNC router is engraving. Most CNC'ers don't realize they can engrave. Glass, soft metals, acrylic, and other materials. Not hard metals. though.

My favorite is glass engraving. The type of tool you use to engrave is called a drag bit. Because it drags. The router motor or spindle is not turned on but the CNC part still does its job, moving around the project as you programmed.

This YouTube video shows it in action with amazing backlighting on glass

I did I remember to mention the tool I use is also used by NASA. The Widgetworks diamond engraver. NASA and Widgetworks...an interesting combination of names. The diamond engraver is found here if you want to look at it. The full list of links are in the YouTube video description.

The router bit starter set I spoke of for CNC router beginners can be seen here.

Happy CNC'ing!
