On topic, seems the small die grinders run at a much higher RPM, while they're for lighter projects (i.e., polishing a steering wheel), sound right? Turns out I have an unused Campbell that came with the compressor say 25 years ago........Go figure.
Edit: Solved the problem of removing the screws from the bed. $20 air drill from Harbor Freight and a single cheap Titanium bit. Apparently my electric drill is a bit tired. That and I saw where you should keep your bits cool with water. Okay, I'm 55, and for the life of me don't know why I've done without a $20 air drill
