Twin Turbine Rotary Grinder Tool Powered by Vacuum Cleaner

This is actually a revision of this https://goo.gl/mHP2Ff but the major difference now is that it's precisely machined, It's more durable, reliable and more efficient. Nothing can beat hobbyist's rotary tools, but it's a prototype that I wanted to try out now that I own the PocketNC (5 axis desktop milling machine).
