The clerk at HD didn't know what it was. He got the expert who said it was a drill without the chuck and with extra torque.
That doesn't sound right; what does the "impact" refer to?

Jackhammer-like action.

It could be something you smack with a mallet or hammer, that tranfers the energy into a "righty-tighty/lefty-loosey" direction. There are pneumatic impact drivers, too, that you might see at the tire changing places. Tom Someday, it'll all be over....
An Impact Drill is a drill that is used for drilling in to concrete or other masonary stuff. You can get a good explanation of how it works at

An impact driver is a tool for loosening stuck nuts or screws. It is sort of a heavy duty Yankee screwdriver, usually with a socket attachment on one end and a steel plate on the other. You put it over the nut or against the screw head, then bash the impact driver with a 2 lb. hammer. It provides a sudden torque that will break the nut or screw loose, or maybe just break it.
An impact driver is a "driver" in the same sense that a screw driver is a screw "driver". Screw drivers are for pulling screws, a hammer is for driving screws.
Okay, thanks; but how does it differ from a hammer-drill?
the guy at home depot is correct. here is a link from makita.
Sounds pretty impressive. The one at HD didn't do anything but spin (Dewalt
12v), but maybe you have to put some pressure on it?Thanks for the link.
No he wasn't. The drill has a chuck...look at the diagram again.
It looks like a eight inch metal tube with a screwdriver sticking out of it. What it does is set or remove stout machine screws. The stubby ones that usually are about 3/8" in diameter, and short. The type of machine screws you take your biggest screwdriver to and can't get it to budge.
What it does is turn, but it uses the energy provided from a blow to its end, and transfers that to the screwdriver bit. They are reversible, so you can use them to tighten or loosen. You position the bit in the screw, and then smack it on the end with a hammer.

Actually, the hammer impact also applies force down on the screw at the same time it turns it. This downward force helps avoid stripping out the slot in the head, and additionally, "unloads" the threads a bit, making the screw turn easier. I used to use it on motorcycles to get loose "frozen" screws.

The Makita and DeWalt use a similar 1/4" hex drive "chuck." The HD expert must think "chuck" only means the Jacobs version. The extra "torque" comes from the impacting portion. Sort of like beating on the end of a wrench.
But, since he said it was a 12v DeWalt, look at this:
Looks like they are all limited to 1/4" hex drive bits.

An impact screw driver is a heavy metal device in which different screwdriver bits can be inserted (they come with the impact driver).
They are used to break loose very tight screws without buggering them up.
Hold the impact screwdriver bit tight in the screw head and hit the end with a hammer (not low impact hammer). This causes the screw to turn a little and and when it is loose, a regular screwdriver can be used to finish the job.
They are most frequently used by mortorcycle owners and mechanics.
You want one? Gpt one I never use anymore.

You are talking about impact drills, more frequently referred to as "Hammer drills". An impact screwdriver is completely different.

I got one that is at least fifteen years old. I use it about every three years. Looks brand new, and is still in its box. But when I need it, I need it, and nothing else will get out that stubborn screw.
If you get rid of yours, I predict you will need one within one week. It happens to me every time.

I bought an Ingersol-Rand for use with my air compressor. Boy, could I tell you stories about rusted in bolts and screws. That impact driver gets them out, pronto. I don't use it normally, but when one of those stubborn bolts turns up, the ol' impact driver comes out and really does a number on it. It sure beats busting a knuckle, or breaking the head off a bolt, or rounding one out.
