Hi Chaps
I have briefly discussed impact wrenches on here before and I know others have also.

I would just like to share my experience with others and seek advice as to whether maybe I am asking to much.

Yesterday I purchased a Clarke Brushless 18V 4Ah 1/2 Impact Wrench with a max torque of 450Nm. It comes with 2 batteries and I charged both fully once I arrived home. It cost £180.

I just popped out to the garage and slackened a 17mm wheel nut and then re-tightened it using a 3/8 torque wrench to 103 Nm.

The Clarke wrench would not un-do it! It just tried and tried and I gave up after it impacting for about 5-10 seconds.

I plan on returning it for a refund.

Am I expecting to much from it??

Would I be best of looking for a second hand Milwaukee unit? If so, would one of these remove wheel bolts etc with no effort at all?

I do not see the point in having one if you first need to loosen. the nut with a bar.

Cheers

Condi

Which torque setting did you have it in?

The highest setting out of 3

I think it's fairly common to find that the lesser brands (Clarke for example) over-egg their torque claims. It's measured over a period of time, so I assume if it takes X number of minutes to remove a bolt/nut then it's still considered fair game to list the torque potential as Y?

I would return it.

As far as alternatives, I use a Milwaukee stubby 12v (3/8) that's insanely good for the size (340nm) and can and has done crank bolts and hub nuts, as well as wheels, obviously. Expensive for home use probably - I use it at work.

A colleague has one of the big Milwaukees (18v - 600nm+) and that is a monster. Overkill for cars possibly. I received a car with wheels lugs on hard enough to warrant 2m cheater bar on one side, and the Milwaukee buzzed them off in seconds.

I also use (at home) a Kielder 700nm/1/2", 18v gun that is very strong (although whether it can muster 700nm, who knows?) and is quite good value although doesn't have the build quality of Milwaukee.

Also have a £50 Silverline corded one that's ok for occasional use and will do wheels.

Milwaukee warranty is solid and 3 years.

Keilder is 2 or 3 years (I forget), and I've used it for a battery failure and been very impressed by the turn-around.

Silverline who knows?

I have had a M18 CHIWF12 for the last 3 years.
It is a great bit of kit, and hasn't been beaten by anything I have thrown at it.
Discovery 3 hub nuts and suspension bolts.
Crank bolts, sub frames.

Good price too.

That Milwaukee is going to undo anything, but probably a bit bigger and heavier than necessary for cars.

I've just bought a Dewalt DCF899HN. Claims 950nm. This seller is selling them for £110 bare regularly - https://www.ebay.co.uk/usr/kaminc-13

I've only got to use it on a couple of wheel bolts so far, and it undid them without any effort whatsoever - two impacts and they buzz off.

I only really wanted something more powerful than my 160nm impact driver (that can't loosen a wheel nut) but figured if I saved £50 I'd regret it when I came to something really, really stuck.

I'm surprised by this - I have a cheap (£30?) Parkside (Lidl) mains impact wrench rated at 300-ish nm. It gets the hub nuts (280nm) off my Megane without *too* much fuss.

The problem for me though is twofold - mains is a pain, despite having power on the driveway it's never long enough and I never have an extension handy - and also it's very big which precludes it being used in a lot of situations.

I used my friends mains powered impact wrench and I thought it was great! It is the only one I have used but it’s miles better than a breaker bar. Combine with plus gas for optimum results.

I recently bought a Makita 18v brushless impact wrench. Must admit I wish I'd bought one of these years ago. They do seem to make removal of rusty old bolts a breeze compared to a breaker bar and spanner. I guess the impact and vibrations must just clear so much more crap from the threads as once it's loosened the nut they just whizz off, also haven't had a nut or bolt either jam or snap yet.

The Makita I bought won't do wheel nuts that have been tightened with my 3 foot breaker bar biggrin, but has been a godsend for loosening suspension odds and sods and makes life so much easier if I can get it in to use it.

I am looking for one powerful enough to do the same plus wheel bolts smile
