hello all
I am contemplating buying a cordless impact wrench , but am I correct in saying its on or its off with no torque adjustment , what are the chances of stripping threads and the like if you cannot adjust the torques setting .

They are great for rattling fasteners off, but I wouldn't use it for tightening them up. That's where you use your torque wrench so you can get an accurate measure of tightness. There is a useful article on torqueing fasteners in this months Practical Sportsbikes I bought an impact gun from Lidl last year. It's for small fasteners really but it's brilliant on screws and bolts under the clutch case, where they get really tight with use and can chew up their heads quite easily. Great tool to have on the shelf Dusty

I’ve got an 1/2 drive Sealey and as said it’s brilliant for stripping down
Especially front sprockets ,clutches,flywheels and primaries but I use a torque wrench for building
A must have in my opinion

As per the other replies, I don't know how I managed without mine, helps so many jobs on strips downs!

I will get a bigger one in the future as mine cant take sockets big enough for clutch nuts etc, but it's proved it's worth having one. In the meantime I have to rely on a long bar and 15 stone on the end of it (me !) to get tight clutch nuts undone, and it's a real faff to do safely. A good rattle gun would spin them off easily Dusty

I have a 18v 1/2 inch dewalt that we use at work for steel fixing it can undo pretty much any thing ,wheel nuts on the trucks etc got the flywheel off my air cooled with it when nothing else would budge it, but I wouldn't use it for tightening ,also have a little 10.8v dewalt impacter and a standard 18v dewalt they are great with a 1/4 and 3/8 adapter respectively get things off or nearly tight then finish off with a torque wrench.

i run one of these 3/8" drive units, its a great small unit for many things car and bike. Goes to 105NM / 77lbsft so good for many things car and bike, but mostly undoing things. What i love most is its small size really, Ive had the large ones before but this does all the tough nuts on our bikes including the sprocket, primaries, clutch and flywheel with ease. Ive pretty much retired my air unit now.

ive got a couple, an air impact for nuts that simply will not give way and a Ryobi one+ for smaller jobs. as stated by everyone above, a must for stripping down.

The force generated by an impact gun is totally different that trying to shift something with one shove, the more you use an impact the more you appreciate how well it works. Leaving the 'rattle' on for a bit, using forward as well as reverse etc works wonders on stuck items.
This type of tool also allows you to hold something like a primary nut or clutch basket nut with just your hand instead of locking it against something and then simply rattle a nut on or off the shaft and lock it up tight as needed. I'd be lost without one now. I actually used my DIY unit that came in a two piece set with my drill to get the 500's case screws out as those units have hex bits. Impact is amazing for difficult fixings.

Yep, I've got an 18v 1/2 Dewalt too. Only those and the Milwalkie ones seem to have enough power to cope with everything. It's yet to be defeated, including wheel nuts on a van that had been done up with a big ass windy gun. I only use it to undo stuck fasteners. Clutch basket bolt, front sprocket etc come right off with no holder / faffing around. Great tool.

Steven, thats what I used to do but I put them in one of my DIY tools, an impact driver that looks like this: It worked quite well as the hex on the shaft fits the hex in the tool, so locks it in tight. This is the same tool I used for the case screws on the 500 as they are allen headed socket screws. What It wasnt much good for was anything with real torque needed, then you need the real thing.
