Query: Awful design: pick another one

Up 'till now, I've always been impressed with DeWalt (price and quality), but this drill . . . is a different story. The chuck on this needs a major redesign; it's almost impossible to get it tight enough. If you're drilling metal, or using round shaft bits, DO NOT BUY THIS DRILL. It works fine as a screw driver (and with other hex shaped bits), however drilling 1/8" pilot holes in 14ga sheet metal: bad idea. The chuck just slips on the drill bit. I'd recommend any other DeWalt drill, as long as it's got a standard keyed chuck.
