I did some "Black Friday" shopping and bought several new tools online, one of which was a $199 deal for the DCD780 compact drill and the DCF885 1/4" impact driver, plus two 1.5Ah batteries. Great deal I thought!
The drill came just in time for me to need to put a hole in my kitchen cabinet for some new under-cabinet lighting. When I used it, though, I can see sparks / electrical arcing inside the drill, visible through the vents that cool the motor. There was also a slight burning smell, but I assumed that was a "break-in smell," and it went away quickly. Is this normal?
I did finish drilling the hole in the cabinet and the tool didn't get hot or catch fire or anything.
I am sure if I call DEWALT they will just tell me to return it to Home Depot and get another one, but I really would rather not do that if it's just got some debris inside or wasn't manufactured perfectly but will work itself out, or if this is perfectly normal for this tool.
Haven't noticed the same thing on some other 20V tools which I just got today also. Incidentally, the grips on these tools are amazingly comfortable and they are surprisingly light-weight, plus the LED lights are pretty great. I'm sold on the new 20V series already.
