Cordless impact wrench recommendations…

[True-Blue]

Evening all, have a birthday coming up and getting a bit tool old for pi55ing around with breaker bars these days…. So considering a battery powered impact wrench.

Needs to have enough power to cope with wheels nuts, knuckle joint bolts, rear lower shock bolts etc.

And recommendations?

Just for wheel nuts..

It’s a bit brutal for most jobs on a Z4

At my point in life I take my time and use hand powered sockets on most jobs..way too easy to cross thread with these boys..

I’m only really thinking about un-doing tough bolts, I’d be doing everything back up with a manual torque wrench

I got one of these. A bit pricey, but powerful and can get in some tight spaces.

Look on machine mart. They do a full range of impact drivers at sensible prices.

The cordless drill type of impact driver are designed for woodscrews, really.

I went for a 650nm mains one, but you do have to hang on tight otherwise it will break your wrist, or do a 'Grommit' and the drill stays still and you spin round! It's a beastie but will undo anything!

Impact designed sockets are sensible too, as normal vanadium ones can shatter with the 'percussion' effect.

£209 including 2 batteries a charger and a case, doesn’t seem too bad.

Powerful enough to undo knuckle bolts to replace front struts etc?

I’d also recommend Milwaukee but the 18v compact impact driver, maybe a bit OTT for DIY but I don’t think you’d want for anything with this.

I definitely want a battery powered one, but good tip re the impact sockets

That looks good too, possibly not as versatile for small spaces as the one Zedebee recommended, but a bit more powerful.

I use both as the smaller one (got the biggest output they sold for that) was great for the abs sensor. The bigger one I use for the wheels

 

[Zedebee]

It’s chunky (shown here with 1/2” torque wrench for comparison), but the right angled format does allow you to get into spaces that many other battery powered impact wrenches can’t reach. 300 nm = 221 lb ft, enough to shake all the rust off your king pins, and changing wheels is a doddle. There are some stuck bolts that nothing will shift, but this beast certainly helps.

 

[pvr]

Yep, that 300 nm is the very useful one. It made small work of my Mc Zed rusted bolts :lol:

 

[True-Blue]

Thanks all, some really helpful replies

I’m just toying with getting a bare dewalt impact wrench mainly because I already have their drill with 2 x 5ah 18v batteries.
I think I should get a hog ring version rather than detent pin, is that correct?
Looks like they do a 400, 800, 950 and nearly 2000nm!
For wheels but also future rear subframe removal and tough old bolts.

I went for the Dewalt DCF900N-XJ - the biggest I could get. It's a beast, but trying to hold it/aim it with a length of extensions when you're lying on the ground under the car can be a pain, due to its weight.

It undid the subframe bolts, and everything attached it to like it was nothing. It undid the hub nuts in a couple of seconds too without even needing to counter the driveshaft (one it was removed from the car).

I paired mine with a 9AH(?) FlexVolt battery (~£90), as my 4AH batteries don't have a high enough discharge rate to delivery the full power (I absolutely hate battery tools. Just give me a cable - now we have to buy different batteries for different tools, and they'll just fail in a few years!). It will work with the 4AH batteries, but not at it's best. Check out this video - it's a different model, but shows the impact of batteries:



Defo go for hogring.
