Link hidden: Login to view has Dewalt and a couple other brands but they have a $60 a month membership fee. The tools are priced too high also.
I see Dewalt and Milwaukee tools on Link hidden: Login to view a good bit.
You probably can't find a dropshipper for low enough prices. Most dropshippers buy from distributors that buy from manufacturers. Try to find a destributor who will dropship for you. It won't be easy.
A manufacturer would be better but almost impossible. You may get a manufacturer to send you to one of their distributors.
