Can this be used in a drill or is an air tool mandatory??

 

I am gonna try a drill, but I know little about this as I have never done it before. I think the 18v dewalts can be turned down pretty slow, if not I guess I will go to the shop where the compressor is but I planned on doin this on in the yard.

 

I used a regular 110v Dewalt 1/2" drill. Works great. Just be careful and let it cool off periodically because the eraser will get HOT when you start bearing down on it for awhile. I was worried about bubbling the paint.
