An electric impact driver is not the same as an impact wrench is it? I have a Craftsman impact (don't know why I call it a wrench, it is not really a wrench in the common sense). Thinking of Christmas gifts. thanks

There are electric impact wrenches.Even battery operated impact wrenches.

They can mean the same thing.

There are small electric impacts, usually cordless, for driving screws. There are also the larger 1/2" drive electric corded and cordless impact drivers. Don't forget the pneumatic impacts as well.

Based on what you are stateing.
Impact driver= Tool used with special drill bits to drill holes into brick,morter and other concrete material,may be powered by battery,household electric or pressurized air.

Impact wrench=Tool used with specialy hardened sockets to install/remove bolts and nuts. May be powered by household electric,battery or pressurized air.

Thanks much, that is what I hoped to be the case. Assume special drill bits needed for mortar? thanks again to all.

You assume correctly that bits need to be not only "masonary" but Impact rated as well. The time required with impact is about 20% of rotare drill.

Well now in looking at the wish book further, Craftsman also offers a "hammer drill", can you educate me further?

I have an 18V Dewalt Impact Driver. It takes 1/4 inch hex shaft bits and drives screws and small bolts. It's a great tool. Once you use one of these you'll never go back to using a cordless drill for driving screws. I use my impact driver more than any of the rest of my Dewalt tools. Such a driver would make a great Christmas gift.

I also have a Dewalt 18 volt Hammer drill. It's basically a regular cordless drill with an impact mode for masonry bits. Then I have two sizes of corded impact drivers. The impact mode is optional -- they'll do straight twist drilling as well. All are useful for drilling concrete or masonry but I use them a lot less than driving basic wood or sheet metal screws with the impact driver.

Then there are impact wrenches. Mine are pneumatic, 3/8, 1/2, 3/4, and 1 inch drive. They take impact sockets and fasten/unfasten nuts and bolts. You can now buy excellent battery operated impact wrenches for "around the farm" work, but I've not yet taken the plunge.

I would say you need to read the ad carefully to make sure it's simply not mis--stated, or poorly written

What most of us call a "hammer drill" is for masonary drilling, and most can be switched from "hammer" to "conventional drill." A "hammer drill" rotates the bit as well as applying a fast cycling "hammer" action vertically to the bit

What most of us know as an "impact driver" could also be called an "impact wrench" meaning a device which applies a high cycle rate impact ROTATIONALLY to a nut, bolt, etc.

Last would be stuff like a "pneumatic hammer" (air hammer), "needle scaler" or similar. These tools apply ONLY a hammer action to vertically to the tool, no rotational action at all. One popular application would be such as "air chisel" used a lot in muffler shops, body shops, etc, to split metal with a cutter bit.

RS:

I've had a 1/2" drive Craftsman AC impact wrench for over 20 years and love it.
