Most consumer tools are made by like 2 or 3 companies, they all have different colors but are largely the same guts within a parent company’s holdings.
Direct tools factory outlet is run by TTI. Milwaukee, Rigid, Ryobi are all made by TTI. Stanley Black and Decker owns Dewalt, Black and Decker (duh), Craftsman, MAC Tools and Porter cable.
Bauer and Hercules are doin their own thing but the batteries are pretty decent.
