I hate to say this but return the Dewalt. IMO they have gone hugely down hill.
All the tools have gone down hill.
Dewalt went down hill, when Black and Decker bought them, decades ago.
Black and Decker's repair parts policy was instituted. Their policy is, to only offer parts for 10 years, after that tool, type number goes out of production.
At that point, they get rid of every part they have, and you can't get anything from them. Including basic things like, brushes, and switches.
That may be okay with some, if they are used commercially, and mostly used up inside of that period.
If I pay good money for an alleged, quality tool, I don't expect to have to throw it away, in 12 years, when the switch fails. I have had this happen to me, and I don't think it's right.
I have heard that the Home Depot versions are of poorer quality than one you get factory direct but I do not know that conclusively.
I have also heard this said about toilets. And, it's probably said about everything HD sells.
I believe it's nonsense. The local people will of course suggest these things, to get you to pay more, when you buy it from them.
I have installed many toilets from both HD, and the plumbing supply houses. The only difference I have seen, was the cost.
