I was kindly given a cheap Impact Wrench for Christmas: Hilka 24v 200Nm..... absolutely useless and couldn't even undo a wheel nut when fully charged.

So I sent it back and got my money back. Ended up getting one from Von Haus instead which has quite good customer reviews, also for £80 and so far it seems really good. Very powerful compared to the last one!! Goes up to 240Nm apparently and I believe it.

My mate Paul has a Snapon one which he calls the gun of fun. It needs servicing now but there was not much it would not undo. The only downside is the price.

I'm running a snap on one now, on full charge it can snap bolts if you're heavy handed when tightening. I previously had a Sealey 19.2 (battery went) and a Clarke (switch went).

Once mine gives up I'll go over to Milwalkee.

I have a ryobi one, it's good but won't spin a wheel nut off unless I've cracked it with a wrench first (130Nm on Porsche).  I'm only using 1.5mah battery and been doing a bit of research into weather a larger battery gives more power as of course P=VA according to science wondered if it translates to raw power at the wrench though?

no it does not give more power. it just can give the same power as a smaller one for longer. BUT the power needed can vary. A in your equation is not the same as Ah.

I bought one of these puppies from Machine Mart 
 

 

Really good value for money I reckon. Made a world of a difference for undoing bolts but I haven't tested it on things such as crank pulley bolts etc

Thank you, good explanation and it's what I'd origninally assumed before complicating things by my research!  The Ryobi impact wrench probably doesn't live up to it's 400Nm claim in that case then!  Still a very useful tool mind you.

Actually that Vonhaus one looks great for the price, its probably better at getting tough stuff off than the Clarke one I bought I bet.

I had a 240V VonHaus one. Unfortunately it was DOA. Well not dead, it just wouldn't engage the impact mechanism. They gave my money back without any quibble though. Didn't even have to send it back.

Got a Clarke one in the end. Seems pretty good. Struggles with wheel nuts that have been done up at a garage to crazy Lb/ft, but that's to be expected. Luckily I have power in my garage, so CBA with battery ones.

And an impact UJ and extensions are extremely useful!

The Clarke and Von Haus ones look pretty similar to be fair. Will see how I get on.

 

Do you need to use the special impact sockets? Someone told me you do.. but the actual thing doesn't say that anywhere.

you should do as standard ones can fracture.

It's also worth remembering that there are a couple of different Ryobi impact wrenches, one is 265nm the other is 400nm. The 400 is very capable but you kinda have to put one of the big batteries in it if for no other reason than you'll drain a small one in no time!
