Not as powerful as air but they certainly have their place as long as they are not labelled Made in China.

Thanks...

I'm also looking at a Milwaukee 9072-22 variable speed 1/2" which does 100/300 ft-lbs.

They are good for running lag bolts. I prefer air for automotive.

I have owned and used electric impact wrenches for thirty plus years. My current one is a Makita that I have had for about twenty years. All I have done to it in that time is to shorten the power cord twice due to the wires failing right at the strain relief. NO BIG DEAL. That's my fault because I wrap the cord around the tool when I am finished with it.

I have also owned and used a variety of air powered impact guns over the past forty plus years so I have had the opportunity to compare the two types.

An electric impact will go anywhere providing you have electricity to run it. It is slightly bulkier than an air gun and perhaps not quite as strong but it certainly does the job. My unit is double-insulated for safety in wet conditions. It does not need a three-prong plug.

Air tools are great but you always need that compressor. Small pancake or hot-dog tanked units run out of air quickly when using an impact so you need a much larger portable if you intend to use the impact constantly. An electric doesn't have to wait for the air to build to 90 psi in order to give you the rated torque. With the electric, you don't have to drag an air compressor to the job.

I own DeWalt and Milwaukee tools and both brands have good reputations. However, my first choice would be Makita.

I ended up buying the Milwaukee 9072-22 kit, which is variable speed wrench. It is adjustable from 100-300 ft/lbs.

I tried it out today and it's a great tool with a detachable power cord, which will help reduce the strain relief issue you describe.

I got a reconditioned wrench with full factory warranty for $170 shipped. It's gonna work out great.

Congrats.. That's an excellent deal. As I said... I have several Milwaukee products such as SawzAlls and drills, both battery type and line voltage. For the most part, they have served me well.

That model is selling new for just over $200 - and can be shipped w/o charge from the amazon.com website. I personally like the looks (and power ratings) of that 0779-22 model - cordless, 28 volt lithium ion. Now if I only had a spare $470.00. But even Milwaukee's 18 volt cordless impact drivers aren't too far out of bounds - running at just over $300.00.
