Impact wrench as a screwdriver?

    Lidl will have a 20v Parkside Impact Wrench next week for 69eu, which is a great deal. I don't do any mechanical work so I just need an Impact driver for my projects, will this impact wrench work for screwing screws, or is it too powerful? It uses a 1/2in drive so I would need one of those 1/2 to 1/4 inch adapters to use the screwdriver bits. Other impact drivers are too expensive, so would this work? Thanks so much

    bad idea in my opinion, for DIY you will rather need combi drill than impact (too heavy, makes too much noise, too powerful), personally I have quiet few cordless drills and one impact which I have used possibly 3 times over 5 years :)

    Yes, amongst ever so many drills and impact drivers, I have Ridgid (AEG) 1/2" driver, that is a tad too big (powerful) for anything less than 4" screws and have had it tested - measured with professional torque wrench instead of advertised 380, it produced actual 250 nM . As a reference car bolts normally done up -120nM, old makhyta advertised as 250nM, only just managed to undo 150nM bolts.
    Also, (unlikely) it is in them figures being advertised as 250, but having ~150nM, you need quality adapter and Wera Diamond impact bits (~£6 each), as they will break every single time you even unintentionally apply any force on them.

    I have a cordless drill from parkside aswell, it works wonders, however I think it would be easier to have an impact wrench/driver along with it, to make jobs go faster instead of having to switch out the bits. This one has 5 torque levels, from 100nM to 500nM, but since I'd just be screwing screws I'd keep it at the first level.
    Thanks for the replies guys:)

    Impact will drive screws in that a normal cordless screwdriver/drill won't, BUT, as mentioned, you need to use bits that are suitable for use in the impact driver.
    Would be without mine tbh.

    I use my DeWalt impact gun for putting in small and very large screws. At low speeds and torque the impact function doesn't kick in and it works like a drill with a screw driver bit.

    Most people end up trashing the screwdriver bits with impact guns through poor technique - not lining up the bit and screw properly and pulling the trigger too hard so it uses full power when it isn't needed.

    Wouldn't argue in relation to 1/4 drivers, where's mine quotes 2200lbs ~250nM, but in reality has no more than ~150-160nM and has all the speed adjustments etc...
    1/2" one, just way bigger, so much so, that it uses different mechanical impact mechanism and no 6 100mm screws simply snap, if not the driver bit etc...
    Sure would make sense pre'drill, be careful with trigger, but where's the fun in that? ;)
