Title: chuck loosens with any vibration
Review: I found that it was necessary to keep retightening the chuck if the operation involved any amount of vibration, like using a hole saw in plywood. I have a DeWalt drill with a keyless chuck and it stays tight in the same circumstances.For some reason DeWalt includes a cheap plastic storage case with some drills but not with others. The cases are made of very flimsy material with crude fasteners. Buying one for a drill that comes only with its cardboard box involves spending nearly $40. Milwaukee and Makita provide sturdy plastic cases with their drills so I don't know why DeWalt does not do the same.
