Cordless impact wrench question

No chance my gun would do that! How do you generally find it in use?
Spot on. Batterys seem to last a good length too. Came with two and always charges up before the next one runs out.Only problem we have had is it stripping a (non impact) allen socket, with it driving away and rounding off the key.
Does sounds like yours might be a bit faulty.
Never had an impact gun before, so I was not sure what to expect. I bought it on the back of a review done in practical classics last year where they rated a 19.2V one well. I have a number of Sealey tools and find them OK. Not in the same league as Britool or snap on, but more than OK for my weekend spannering.
I've got one of these (except I got mine from Maplin)...

Cheap as chips and, amazingly, I haven't yet found something it won't undo (that includes wheel nuts, crank pulley bolts, brake caliper bracket bolts, etc).

On what, an RC car? I find it hard to beleive that would undo a crank pulley bolt, certainley not on my car.http://cgi.ebay.co.uk/12V-DC-ELECTRIC-AUTO-IMPACT-...

I don't know how the battery ones work, but I've got a 12V one and it sort of winds itself up and hammers bolt undone with a blow every few seconds - it undid some wheel bolts that were absolutely solid and I was convinced would snap (I have had them snap in the past).Deva Link said:

Yep, that's the one... nowhere near as fast as a 'proper' impact wrench, but surprisingly effective and v.useful to have around for those once in a blue moon scenarios where you need one (obviously I'm talking about DIY here, not a professional garage environment!)rickyw said:
I treated myself to one of these a few weeks back as I have a few on going jobs and I thought it would make life easier. The one I went for is the Sealey CP2450 as on paper it looked good.
Anyway, I went to use it in anger yesterday & I found it struggled to remove wheel nuts & would not even look at the crankshaft pulley bolt I was trying to undo.
Anyone got experience of these?
I've got the older version of that model (18V and 285lbft) and that won't touch crank bolts either, but to be honest, I didn't expect it to Anyway, I went to use it in anger yesterday & I found it struggled to remove wheel nuts & would not even look at the crankshaft pulley bolt I was trying to undo.

It will undo wheel bolts with a freshly charged battery, but not as quickly as you might expect. Certainly not as fast as an airgun.I only really use mine to put wheelbolts back in quickly now, then hand torque them.

Got something similar from Aldi a while ago ,it's gathering dust under the bench fin usless ,buy a 24 " power bar and then scrounge 3ft of ally scaffold pole your troubles will be over
Lol, the tried and tested methods usually save the day I was hoping my trusty Sealey would remove the crank bolt on my Rover(torqued to 205nm), thereby avoiding having to buy a flywheel locking tool and breaking yet another 1/2" breaker bar, but nope.
It's the kind of thing a snap-on gun would wind off in a second...

My experience comes from strip/rebuilding a large number of Duetz engines in materials handling machines , the largest being 10 ltr v12, another trick on a crank pully bolt is a sharp crack with a 12lb hammer and a suitable drift loosens most things!I have two 24v Cordless Impact guns and they have worked well for years. They will not cope with an overtightened wheel nut let alone the 22mm Crankshaft Pulley Bolt on a Rover K-Series or the 19mm version on the Rover O and T Series. Stubborn ones of the latter need to be loosened a tad manually first.
Needing to renew the Timing Belt on my son's Rover 25, with one hugely overtightened Crankshaft Pulley Bolt in previous ownership, because they are never that tight from the factory. Even my 240 Volt Impact Gun would not cope. No other Nut or Bolt has proved a problem. Even holding it firmly against that 22 Bolt Head and having the numerous Impact Pulses try to shift it for about 20 seconds, that usually works but not this time. This is the 240v Impact Wrench. :~
Anyway, not going to be beaten by it, I deployed the following ... manually. This is the arrangement I use with very stubborn Bolts, Nuts and Plugs. Using an Axle stand to support the 3/4" Breaker Bar allows you you use all your weight, in my case 16 stone, effectively on the Breaker Bar. Even that did not work for my son's Pulley Bolt. With his foot firmly on the brake pedal and in fifth gear, I used a six foot length of scaffold pole over the sturdy breaker bar and that at last worked :~
For the amateur DIYer, a few minutes thought and preparation can overcome most things.
One repetitive job I use the 24volt cordless jobbies frequently for is with say the numerous 8mm bolts which secure some Camshaft covers on engines. About two dozen plus with some Rover and MG engines. As they are threaded into soft alloy, I always undo them a turn or two by hand first. Then use the imapct wrench. saves much time and less wear and tear on the wrist muscles. For that reason alone they are worth the money over the years.
