It's been quite a saga. I use the drill the most so when it started wobbling within a few months I bought another so I could still work while I sent it in. The new one developed the wobble within a week. I sent it in immediately upon getting the first back, and just swapped them in and out a couple times. I called Dewalt, and they don't care at all, just referred back to the service center.
Finally got one of them back with a new chuck. No change so it must be the spindle, inner case or some such thing. Next swap-out I get a brand new drill back. Date code on it is TWO YEARS older than the one I sent, essentially stealing my warranty time. Same problem on this one too, and Dewalt doesn't give a damn.
For reference, this is the DCD995, premium brushless hammer drill. I rarely use the hammer function. I've taken brand new half inch bits, clamped a piece of scrap onto my bench and drilled. It shakes the bench hard enough to open a drawer and start my **** can wobbling.
I figure I can sell it all for around $600, and between the current HD promotion and Amazon replace it all for around $850.
