Homebrew PCBs

I don't have a dremel, just the minicraft drill
surprisingly it is now over 10 years old, and as well as drilling 
100s of thousands of pcb holes, it has drilled over 80 thousand 4mm 
holes in steel and plastic about 2.5 mm thick as i used it as part 
of a production tool in my previous business.

It seems to be incredibly robust.

I have mentioned before that the proxxon collet chucks are 500% 
better than the dremmel ones, i don't know about the motors though.

I have heard it said that the best motors for this application are 
the brushless motors used for model aircraft.
However, you need an appropriate motor speed controller to run them.
So for me the price outweighs the noise from the current setup.
