One of the best places I like to use this tool is whenever I need to put tap con screws into either strapping on concrete floors or wall partitions in basements. The mere use of connecting sockets to this tool is a very simple and fast way to drive in the screws with the hex heads. I find a standard Common or Philips screw head can quickly strip when trying to screw them down through the wood studding used for sill plates or strapping in the case of a sub-floor into the concrete. The older the concrete floor, the harder it can also be as concrete will harden up through the years when poured. Screwing in the hex heads usually always works best in this case for tap con screws.


Another time I find that the dewalt cordless impact wrench works well is when you need to drive in lag bolts for getting your rim joist in place against the house. In fact, anywhere you need to drive in lag bolts this type of tool will make easy work of it. It works out that any place you can think of using a socket set you can use this tool instead. One key caution is if you require a preset torque wrench then this impact wrench is not the proper tool for the job as a torque wrench requires perfect precision for a targeted amount of tightening such as a particular measurement in inch lbs. An example would be the torque needed to fasten the head, gasket, and engine block together or something as simple as the torque used for your engine spark plugs.


So any place where you do not require a precision torque value then the cordless impact wrench will do the job a lot faster than using wrenches or ratchets from your socket sets.

Now depending on how much work you do with regards to using socket sets, you can just get an impact drill that can do everything the impact wrench does by simply inserting a socket
adapter into the chuck. The reason some people prefer the impact drill is you can also use it with all your standard bits for driving in screws from your regular drill. You see a lot of people like using the lighter impact drill rather than, the heavier drills. So if you do have the impact wrench, you can still drive screws in by using the socket version of the screwdriver bit sizes from your socket sets. Which tool you’ll use the most comes down to what you do the most, do you need to add a socket adapter or screwdriver bits the most. People will tend to buy the tool they’ll get the most use out of that also saves them the most time.


I already have a hammer drill that replaces my screwdriver so the impact wrench works best for me so I can forego the ratchets from my socket sets and use just my impact sockets. I use the impact sockets mainly for the extra strength compared to just the regular sockets that most people have. So you know, a lot of contractors do use just the regular sockets on their impact wrenches.


So whether you’re working on parts of your vehicle, around the house or installing a new deck. You will find that the Dewalt Cordless Impact Wrench will have plenty of power to do the job at hand and for the durability, let’s just say mine is just over ten years old now from my combo kit and works like the day I first got it.


So treat yourself to a power tool that replaces your hand operated ratchets if you do not presently own one and try out this cordless impact wrench.

  1. Hi there,
    I completely agree about hex headed screws over Philips. Phillips are fine to putter about with, but as you pointed out, concrete and steady use is a whole different matter.
    Seems like they’ve made a pretty versatile tool on this one. I’ve always liked Dewalt cordless tools. They’ve always served me well. Well done with this review.

    • Thanks Brian for the comment and like you mentioned and I had said in my post the hex heads over philips screws definitely have there advantages and just as dewalt has served you well I know a lot of other people will agree with both of us on how good they really are.

  2. I’ve owned a similar dewalt tool to this for about 6 or so years now and I must say the performance of these things are simply amazing.

    On the job, charging up a battery takes and hour or less, battery life isn’t too bad as I can use the thing all day and then some. My only thing is I’d like to go with the lithium battery later on, I’ve seen great reviews on them.

    • Well the great thing about the tools today is you can get the lithium batteries for your regular cordless tools when dealing with the better brands. The tools themselves just need the required voltage and amperage to draw on so if the company’s tools you use have lithium battery packs designed to fit your tool you can change over from the nicad battery to the lithium without having to repurchase the tools over again.

  3. Hello,

    First off all I really like the overall look off your website, it looks really professional!

    About the post, I have to say I was confused at first. Maybe it’s because I’m Dutch speaking and I don’t know every word for working tools. But when I think about a wrench it looks totally different, this tool looks more like a drill to me. Is it my language?

    Go on!

    • Hi Rian and you’re fine for understanding that this is a tool to replace using a hand wrench. This tool was designed to use sockets straight out of your socket set for work. Most people see these tools at a garage station when they take the nuts off to change or rotate your car tires. They use an air compressor instead of batteries and electricity from a cord, but they are still impact wrenches.

  4. Hi Travis,
    I often have trouble with the Phillips screw heads when I’m screwing into concrete, next time I’ll take your advice and try hex heads, sound like a great idea. Using a cordless wrench would certainly make this task so much easier.
    At the moment I haven’t an impact wrench but I would probably go for an impact drill as I can use all the standard bits. Thanks for the great info on your blog.

    • Hi Peter and the good part of having a impact drill is you can still do everything the impact wrench can do plus you’ll be able to drill with all your standard drills as well.
