Hey guys thanks for the feedback. After reading and posting in a few sites almost everyone has told me that my compressor isn't going to have enough juice to run a grinder. It might but it would be on non-stop and craftman says to not have it on for more then 15 min.
So I may opt now for a high speed drill. Figure I can reuse a drill down the road.
I'm looking in this: Dewalt217 (0-4000 RPM)

I have had some serious issues trying to find a high speed drill. I figure at 4000RPM I can slap a 4" buff on this and be fine. All the other drills I have found run at 3000 or 3500 kind of odd I thought.
Anyone have any feedback about the drill situation? I have read up in the forums but not much data turned up.
