Seems from their web site they are being made everywhere the parts I like their 3/8 impact driver and we use four of the construction radios in the greenhouses which is one of the few that have stayed running with all the moisture. I have two of their drills but honestly still go to my old 20volt craftsman for any big jobs. I just find it lighter and feels better in my hands and I can control the screw driving better. Might be just me also from using that style since they came outI been using dewalt power tools my entire career amongst others like milwaukee metabo makita bosch hilti etc and dewalt out performs and out lasts all of them if china is making the parts for them id say they are doing a fine job.
Lots of bosch here pretty much all my corded stuff and the cordless drill I may have out of the case twice again just didnot like the feel. Had a dewalt table saw and also didnot like it or how it handled plywood so sold it and back to my vintage craftsman there
Some history on the parts here
In December 2013, DeWalt issued a press release stating it would be bringing some assembly of a small selection of their products to the United States using globally manufactured parts from Brazil, China, the Czech Republic, Italy, Mexico, the United Kingdom, and the United States. The products assembled in the United States would be branded under the label, “Built in the USA with global materials.”
