I’ve a brand new Dewalt 14.4 impact driver. How well will it work for drilling 3/8″ holes in concrete? No rebar is in the way.

I'm guessing, Not very. The impact action is tangental to the shaft on an impact driver, whereas a hammerdrill (or rotary hammer?) the action is in line with the shaft, making it more effective on concrete (like comparing a wrench versus a hammer?) That's my guess, anyway. But hey, give it shot and let us know how it works. You might discover a whole new use for the little buggers.
It'll work great for driving screws but I doubt it'll drill concrete worth a dang. You should probably have bought the version that holds the drive tips directly rather than the version with a chuck... just my opinion. Anyway, once you drive a few screws with it you'll never use anything else.
