Cordless Impact Wrench

Hi All,

I'm looking to purchase a quality, dependable cordless impact wrench. I've done quite a lot of research including reading through forums such as this one and of course, there's no simple answer to which one is 'best' ('best' can mean different things to different people) so I'm just trying to gather peoples' experiences and thoughts before I plump for one or other.


My short list currently stands (in no particular order) at (clicky links...):

Ingersoll Rand W7150

Hilt SIW 22T-A

Milwaukee HD18HIW402C


I've put the Snap-On options (and a number of others) to one side, at least for now.

My priorities may be different to others but, roughly in order, they are:

1) Must perform to my requirement as close as possible to 100% of the time I need it. In other words, if I find it can't shift the last bolt I need undoing, I won't be happy consoling myself with the the fact that it was cheaper than a better wrench that would have undone that same bolt!

2) I don't need super-extended battery run times because I won't be using this hours on end, days on end. This is hobby/DIY/vehicle enthusiast use and I'll rarely find myself in the position of not being able to wait for it to take some extra charge.

3) I do need excellent battery charge retention and long term health. Partly because of the above, the tool/battery may spend weeks on the shelf without being used/charged and I don't want to find that after a few months, the charge capacity has dropped to an unhealthy level.

4) Because it isn't going to get regular usage, it will probably be years before the usage level takes me into 'warranty repair' territory but by then, almost certainly the warranty will have expired. So good warranty terms and customer friendly manufacturers would be a bonus :)


On paper, looking at the 'brute force' performance figures, it looks like the order would be:

1) IR W7150 (see below)


  • Working torque in forward 68-746 Nm
    [*]Maximum torque in forward 813 Nm
    [*]Working torque in reverse 880 Nm
    [*]Maximum torque in reverse 1057 Nm
    [*]Nut busting torque in reverse 1486 Nm​

2) Miwaukee HD18 (610NM)

3) Hilti SWI 22T-A (450NM)


I do wish to cut through the marketing hype wherever possible (what on earth is 'nut-busting torque?! :shocking: And how is it different from normal 'max torque'?!) and I totally understand that numbers on paper don't always translate to the tool at work but, the IR figures do look quite compelling.


In terms of opinions I've read, there's been a huge variation.

Some appear to have suffered significant supply issues withe IR and I even saw a couple of thread posts which commented on it being cr@p, which I find a little hard to believe. But there's plenty of other indication that it's a super impact wrench.

There's a lot of positive comment about Hilti (to the point of it being a brand of super-mythical proportions!) but equally, I've read comments from people saying that whilst some Hilti stuff is brilliant, the cordless stuff is merely average. Also, that spares are difficult to come by and the 'capped repair cost' programme can still be very expensive, with Hilti frequently opting to replace the tool and making a significant charge.

On the other hand, I can't seem to find anything bad about Milwaukee as a company, or the HD18 and it also seems to be the best value for money too; in fact the cheapest of the three!


In terms of budget, whilst I don't have limitless cash, my philosophy is that the only thing worse than spending too much, is not spending enough :)

I'd be very interested to hear the views of those that either own one of these impact wrenches or especially, from anyone that has used more than one of them, perhaps even swapped from on to another.

Many thanks for the help and advice that might come my way.

Cheers! :beer:

I had the figure of approximately £500 in my head to get what I'm looking for, but I'm prepared to go higher if there is compelling reason to, for a more capable wrench. This is a long term relationship, I hope, so can justify it over a number of years!

Also, what I'm saying is that, to me, spending £500 on a wrench that is effective only 90% of the time is worse than spending £600 on a wrench that is effective 100% of the time.

I'd rather 'waste' £100 on a wrench that was over-spec rather than 'waste' £500 on a wrench that was under spec and would forever annoy me. Worst case I might end up having to buy another wrench (perhaps the one I should have bought in the first place!) and that's a whole lot more expensive in the long run! Hope I've explained myself.

Country is UK.

Thanks.

How much willing to spend??

What country??

Since he mentioned three models I would be willing to venture he is willing to spend whatever those three models cost at his location.

This should be an interesting thread. I have been debating between the Milwaukee and the ingersoll for a while now.

The one thing to keep in mind that the "best' and "most powerful" is an ever-evolving term in terms of battery operated power tools any more.

What in what year is the best can be usurped or completely outgunned the next (Milwaukee and Bosch with the new brushless motor systems for example.) Same for battery design and type. Always growing in power and updating charge holding system.

As for cordless impacts, if you were in the USA, I say Snap-On. Period.
High price but dealer and factory warranty/repair service is very easy and the batteries will be aviliable for many many years to come.

Almost all of the local AAA/roadside assistance trucks here (similar to AA-Automobile Assisiation in the UK) use the Snap-Ons with a smattering of Milwaukee's and IR's. And that's a service that needs high power dependable tools everyday for roadeside fixes and flat tyre changes.

In fact you might want ask a few of the AA drivers and see what they use. :)

I do not know if Milwaukee tools are heavily supported in the UK? If so they are very good, but IR may be the best choice due to availablity and long term warranty work if needed and battery choices well into the future.

I see Snap-On's Milwaukee's and DeWalts used in a professioanl mfg. setting every day and aside some from issues with DeWalt battery failure over time at a much higher rate than the other two brands, all three have been dependable and reliable day in and day out.

I have not used an IR cordless impact mainly due to availablity and such a small support system outside of the internet and the hit or miss industrial suppliers locally. IR air tools and service is everywhere, the IR cordless system is a little more difficult where I am.

I'm not familiar with the Hilti corldess impact line so I cannot comment but the Hilti corded power tools I have used or rented in the past have worked spectacurlarly.

Good luck.

Maybe the older IR and Matco, but not the new ones. They're all powerful guns though.

Ingersol Rand W7150 puts the Snap On to shame.My Matco tool dealer stops at a county road commission garage.Tightened down a lug nut down on one of their trucks.The IR W7150 took that lug nut off with no problem.Then an employee that is nothing but Snap On came out with his Snap On cordless impact,would not remove that lug nut off after tightening it again.The IR has the better warranty too.

The IR is a beast I have been beating on it for months on end I have only had a handful of bolts it would not undo but my IR TI couldn't and neither could my mg725 had to loosen with long snap on 1/2 ratchet then put the impact on them.

I remember a youtube video of a guy that has a ? tourqe dyno? not sure what else you'd call it. Computerized dynomometer with a 1/2 square drive input. Anyway, they ran the IR/matco gun against the Snap-on, It was pretty impressive. The IR put out almost 100 ft lbs. more.
As to the OP though. As far as I've ever seen, Nut busting torque is just a BS number the manufacturer throws out to sell their product. I always look for "working torque" and compare the numbers. They seem to workout in reality alot better that way. All in all I think milwaukee makes an excellent product but, if the IR is in your price range definately go with that.

Huh? It's supposed to be IR cheaper than SO

I dono about IR pricing but the matco model is more expensive than SO, and you only get one battery in their package. But powerwise, you definately get what you pay for. I think the matco setup was like $750 last time i remember. Absolute insanity! I'd never buy one, would love to have one though

How are the Dewalt 18v?

They worth buying I am considering one.


I have the dewalt 18v if you don't mind hammering on lug nuts for a while it works but it is very weak I would try to kobalt before buying the dewalt but at the point the craftsman c3 sounds like it gets more positive reviews. And if you got money to spend the IR is only 3 something with 1 battery and it is a powerhouse.

I think the dewalt is more aimed towards putting giant lag bolts in wood beams or something

The Matco impact is not made by IR. There are no rebranded versions of the W7150.

I have the Milwaukee M18 and I couldn't be happier with the way it's held up. I really haven't run into anything it wouldn't handle and the battery holds it's charge forever. I hardly ever use my air impact anymore it's just easier to grab the electric. I can let it sit for weeks, pick it up to use and the battery will be like I had just put it down. I have several Milwaukee tools and think highly of them.

I don't have one, but maybe 2 yrs ago there was a review in either "Family Handiman" or "Car and Driver" on cordless impact wrenches. I believe a Makita got top nod. You can see if that review covered any of your choices.
