Is it possible to attach a buffing pad to this tool?
I'd like to double the use of this to include buffing for furniture finishing and auto polishing. Anyone have experience with this?

Great tool
I don't know what I did before I got this- I'm using it all the time. I'm glad I got the longer handle. Adds stability and easy grip. I can still lock the trigger for the rare one handed operation. Wire brushes are hazards- get a face shield.
ProsPower Long handle Versatility
ConsWish it came with a thin wrench for attaching self hubbed items like wire brushes.
