You've got them mixed up. DeWalt is Stanley Black & Decker, which also makes modern, non-Sears Craftsman tools, along with a bunch of others--Bostitch nailers, Irwin, whatever's left of the Porter-Cable line, and upscale stuff like MAC (uses DeWalt batteries, as it happens) or Proto. Milwaukee is TTI, which owns Home Depot's exclusive Ryobi and Ridgid brands, along with Empire (measuring devices), Hart (Ryobi but for…
Pretty well summed up. It's an even hairier mess when you look at the details. For example, TTI licenses the Ryobi name from the Japanese Ryobi, and produces tools for Ridgid while not actually owning the brand. The odd one out usually forgotten is Positec. They have a rather interesting history, and today make the Worx stuff...which honestly aren't bad tools.
I have since switched to all Milwaukee however. The battery tech smokes everyone else and the high prices are easily justified by quality and productivity.
The productivity, and subsequent quality of work, from the Fuel line are worth upgrading from down market stuff. If you do your own work (remodelling etc) there is no comparing to the bbq dad tools (or harbor freight).
The weed eater is stellar. The blower can be operated with two fingers (you can hold it with one finger). Damn thing tries to leave your hand though...lol
Smallest hammer drill, short work of any masonry (with decent bits). Done. Move on.
Circular saw lasts all day under heavy use (6 xc battery).
Impact driver...it is always out and ready. Used constantly. Driving tapcons, building decks, working on the truck, drywall. All effortless. Every screw and bolt driven perfectly without issue.
Literally an investment.
