So I'm in the market for a couple of impact wrenches for occasional car and bike type use

Something I can use to remove car wheels, tighten up nuts, bolts, undetray screws etc... 

Not looking to spend £££££ but want something that will last and have good power/torque and want to spend around £100 per tool

I've always used my compressor for these type jobs but its a pain to get it out set it up when only being used occasionally so want something I can grab and go

As this is my first foray into cordless tools I'm not currently tied into one brand due to battery compatibility but after I purchase one I'm know I'm going to be stuck with that brand unless I want to keep buying batteries for each different brand I buy so want to get right first time

I recently got a 3rd gen Milwaukee M12 1/2" impact driver for just a tad over £100 (bare) and it is crazy powerful for a 12V system (over 700Nm) and very compact. It made short work of an extremely stuck bottom bracket, but other than that it is too much for bikes where the 1/4" hex impact or drill driver are more appropriate.

I like the M12 system, it is powerful for a 12V system and mostly fits my needs although the drill/ 1/4" impact is still a bit short of an 18V system. I think it is the only cordless system with a file sander, which I also recently got to save on faff getting out my plug in one.

For more flexibility in a single tool the Bosch GDX fits both 1/2" and 1/4". I bought one of those on sale for £65 from Screwfix for my dad as he uses that 18V toolsystem.

Makita LXT here and every tool does it's job well. Don't buy non-Makita batteries though, they're bobbins.

Having said that everyone at work swears by the Milwaukee M18 stuff we use for humongous industrial process kit. Nuts that are 5" across, that kind of thing. Might be overkill for car wheels though.

Cheers for the replies

So after doing some research I've kind of settled on the items in the link below, had to up my budget by an extra £100 to cover batteries and a charger

I don't get anything on the link.

Impacts vary quite a lot, I have the basic Makita LXT one and it's a workhorse, subtle enough to do fairly small stuff but it'll still do most bolts on cars. I very rarely use it on a bike though, in fact maybe I've only ever used it for DT240 hub rings where it is a godsend.

But it's not mighty, it definitely has a limit. At the other end my mate has the big brother one and if you bolted it to the north pole it could reverse the world- but it's heavy, really pretty clumsy- you don't ever use it for little stuff- and tbh most people will rarely if ever have a use for it (it's completely awesome for, frinstance, scrapping rusty-as-hell Subarus that are basically fused into one block but that's not normal person work) So he ALSO has the same one I have and uses that like 95% of the time.

Mostly when the little gun can't handle a job a big breaker will do it though so I've never really been tempted to spend the ton of money to get a big hitter.

Oh yeah be aware they can be battery intensive- I mostly use the 3ah batteries as a compromise size but they won't drive even the little impact at full power, 5ah seems to be the minimum for that, you lose quite a lot of capability at hte top end. Yes I am aware that ah is amp hour not a maximum current rating but the bigger batteries usually also have more ability to deliver current.

Borrowed my son's Milwaukee M12 one when undoing the bolts on the rear shocks on the mighty Octavia. Got a bit warm but did the job, which was impressive for a fairly small and lightweight tool. His friends run a garage and they have it's big brother, apparently it's a bit of a monster.

Don't think I'd fancy using one on a bike though.

There may be some good deals here....

Your basket link is tied to your own browser - everyone has their own basket. So we don't see what's in your basket.

The only thing I'd imagine using a power tool for on a bike is spinning in rotor bolts, prior to torquing by hand.

If you're looking for a "couple", rather than get impact wrenches (i.e. male square drive), consider getting one of those plus an impact driver (female hex drive) and/or a power screwdriver.

Perhaps I'm missing something, but when would you use an impact wrench on a bike?

stuck bottom brackets, the wrench is mainly for cars, the driver is for bike and car use

I bought a Milwaukee drill and driver combo a few years back, wish i’d done it years before instead of messing round with cheap crappy drills.
