Is it possible to attach a buffing pad to this tool?
By Mike from CT on March 14, 2014
I'd like to double the use of this to include buffing for furniture finishing and auto polishing. Anyone have experience with this?

I would recommend this item to a friend.

Great tool
By M Albert from FL on April 29, 2013
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.

Long handle
Wish it came with a thin wrench for attaching self hubbed items like wire brushes.

I would recommend this item to a friend.
