Electric Impact Wrench

[ba614]

Yesterday we had a disscussion on cordless impacts. What about the electric models? Seems you can get more power for less money. Dragging an extension cord isn't that hard to do unless you are somewhere that there isn't any power. The electric impact would be usefull for someone without a good air compressor and could be used places where no air compressor is availible.

What is your experience with these?

Who makes the best?

they have the 052-057 line which is a compact driver and wrench depending on the number. then they have the big boy 18v 059. they have a 36v Li right now but i dont know to much about them i didnt work on that project.

forget it for electric impact wrench if you plan use it more often because it will get more hot and can have it smoking out of motor if something stuck on while you keep impacting on.

electric impact wrench good for simple thing like tires rotate or something that basic.

I'll have to disagree. I assume the electric impacts of today are at least as good as the ones from 30 years ago. I have a 30+ year old Craftsman variable speed electric impact. It has preformed well and I have gotten alot of use out of it. When I have something the air impact won't get loose, I get the electric out. This is a very handy tool to have, since you can take it places you don't have air. I rate the electric impact as one of my more useful purchases over the years.

My dad has an old Rockwell 1/2" electric. Bought it at a garage sale for $2. Brought it home, cleaned the contacts on it and we've been using it ever since for taking rusted bolts and nuts off old mower decks.

i am use air tools and dont want use electric power to do impact as never know that you plan use it and have to use while rain then got electric self.

Cannot say that I've ever tried to use any electric power tool outside in the rain before, just doesn't seem normal.

I've just found too much use for one to simply say you shouldn't get one.

They are big and bulky compared to air models, and they certainly won't get into every place, but I've taken it up to a neighbor's place to work on her tractor, I've loaned it to the next door neighbor for removing blades from his 3 pt hitch mower, I've removed many a wheel/tire with it, I've used it for running lag bolts into a wooden swing set I was helping a neighbor put together for his grandchildren, at his son's house, 75 miles away, out in the backyard, its just a versitile tool.

i just dont want use electric impact wrench because i use air tools to fit where i need to go. i just try stay away electric impact wrench because i use it and push too hard. so i prefer air tools because i already have lot of air tools.

but for anyone who dont have air compressor then electric impact wrench would do good for simple work.....

I bought a Craftsman 120 volt electric impact wrench about 15 years ago to get my self out of a jam 800 miles from home. Since then, It has been quite useful. Sometimes when you are trying to loosen a frozen bolt on a rotating assembly, there is no substitute for the impact wrench. If you do not have access to air,this is the next best thing. I am using mine all the time now since I lost one underground leg of the power that feeds the sub panel in my garage (my compressor is 220 v)

I have noticed that using a heavy duty (12 ga.) extension cord makes a noticeable difference in power even for short runs.

An Alternator fan/pulley nut comes to mind, quickest way in the world to get a Ford alternator fan/pulley nut off is to wrap in in an rag and throw the impact on it.

After I built my shop, I ran a 100 ft 12 gauge extension cord from the back porch of the house out to the shop. It lay on the ground for a year till I finally got power on the shop. Used it to run all kinds of things. Cord is still in good shape even after a year of weathering. Now I have the original 100 footer, a second 100 footer, an 80 ft and a 50 ft, all 12 gauge. I get all kinds of use out of them around the house, shop and yard. Also have about 300 ft of 16 gauge cords I've acquired over the years.

I like them a lot. I have both an older BD and a newer DeWalt (DW292). They are essentially the same design (because it is a GOOD design).

Very handy for all of the reasons mentioned. They are also nice for those occasions I get "volunteered" to do some work for relatives that don't have air compressors.

I helped some relatives build a deck and patio cover...I showed up and they were cranking on lag bolts with Crescent wrenches, etc. I broke out the impacts and was a hero. I sat down and drank their beer and watched them work.

No need to run 12 gauge extension cord for the electric impact gun when most household wiring inside the wall on homes are done with 14 gauge where you plug it in. I would run 14 gauge extension cord instead since it's more flexiable and easier to coil back up than the 12 gauge since you don't notice the difference unless the wall outlet in the house is wired up with 12 gauge from the fuse box. The cord on the impact is probably 14 gauge to start with so it will just bottle neck into it. I've brought a Canadian Tire Mastercraft 120 volt 1/2" impact gun during the Christmas holiday on sale for 49.99 from a regular price of 149.99 with a 3 year guarrentee.

I must confess, it's not entirely true. Once the impacts came out, they were fighting over them, but I did assist with some predrilling and layout.

There were also some operations I could assist with while staying near the refrigerator, i.e., holding the end of the tape, chalkline, or level.

If I had three electric impacts instead of two, I would have been home free.

And honestly, I normally have a problem watching other people work (I want to jump in)...but in this case, it was well-deserved.

But still, you drank their beer.

Thank's for the replys.


I am looking at the Milwaukee 9072-22 kit. It is varible speed 600 - 1800 rpm and 1000 - 2600 beats per minute with a 7 amp motor. It's rated at 300 ft lbs of torque and weighs 6 lbs.

The other one I am considering is the DeWalt DW292K. It is not varible speed. It's no load speed is 2100 rpm and 2700 beats per minute with a 7.5 amp motor. It's rated at 345 ft lbs of torque and weighs 7 lbs.

I am leaning toward the Milwaukee due to it having varible speed and being 1 lb lighter. It does cost $40.00 more than the DeWalt but I think the advantages of the Milwaukee's varible speed and lighter weight justify the extra cost.

What do you guy's think?

 

[wilbilt]

It depends what you are working on. If you really need to be able to limit the impacts and rpm, the Milwaukee sounds good.

If you need to get the job done in a heavy-duty fashion, I can personally vouch for the BD/DeWalt.

 

[RPH]

Being a field service engineer it's nice being able to use my electric impact as 110 vac is alway's available but air isn't alway's available.

 

[Sundowner]

I have a bosch 1" electric impact (yes, 1" drive) it's a heavy mother, but I'm 99% certain it's rated to 1000 ft-lbs of torque. That gun has broken bolts free like no air gun i have ever used. It was not a cheap gun, I paid something like $300 for it used, but it makes the DeWalts and Milwaulkee guns look like toys.

please explain how you would burn up the motor. its designed to have no reactionay torque. meaning all the load is in the impact mechinism. the motor spins at the same speed no matter what (unless you move the trigger) so basicly if its stuck on a bolt its just gunna free spin and beat on it till you give up or the battery dies. not like a normal drill that bogs down when you get a tight spot

The other advantage to Milwaukee is the warranty. 5 years vs. 3 year limited for DeWalt.

To me, it doesn't make sense to buy a tool that doesn't have all of the features you want or may want on it. You may never use the variable speed, but you'll have it. Lower weight is almost always a plus in a power tool unless the OEM is using plastic or composite when it should be metal - don't think this is so in this instance.

If it was my money, I'd go with the Milwaukee in a heartbeat.

I have a 40 year old Ingersoll 1/2" inch drive impact. I love it. Before I had air tools, this was my only power wrench and it did its share of mechanical work. It only needs minor maintenance (repack the hammer drive with high temp grease every 5 years).

I recently used it to build my deck -- tightening up a 100 lag bolts was very easy with this old gal. Don't know how the HF Chinese models hold up -- but they are selling them cheap.

esrever engineering makes it easy...most of the china knock offs are copys of the the 40 year old dw290

By all means get the variable speed. Having a variable speed electric is no different than a variable speed air tool, you will encounter cases where you just want to tap stuff tight (such as lugnuts) and then finish the job with a four way hand tool.

ROFLMAO....


Too bad it's the truth though, and the US gov't won't do anything about it.

Well guy's I ordered the Milaukee last night from CPO Milaukee for $219.95 plus 7.95 shipping. It comes with a box and 6 impact scokets. I'll let you know what size's the sockets are when it arives.

I just downloaded the 2006-2007 Milwaukee catalog. Your kit is on the bottom of page 80.

Sockets are 1/2", 9/16", 5/8", 11/16", 3/4", and 13/16"

I put a copy of that item in this post so you don't have to sit through a 34 mb download.

Do you have the website for CPO Milwaukee? I have a few tool purchases to make in the coming weeks / months and its always good to have another site to check prices on.
