  1. Nathan Grafia

    As the leading Emergency Roadside Service Provider in the U.S., we have countless flat tire service calls, and this Impact Gun hands down is the best for the price. On a fully charged pack, I can easily replace 6-7 flat tires (4-5 bolts), and this comes with 2 battery packs. Even on our own trucks (8 bolts) F350-450, I can easily do 4-5 without losing torque. Gun, 2 batts, charger and bag…..I HIGHLY RECOMMEND to all my drivers and anyone in this field

    It comes with 4 amp/hr batts, and a scaled up charger from my 2 amp/hr DeWalt drill. The bag included is strong, though I don’t use it. The tool itself hasn’t given me any trouble removing/replacing fasteners. Battery life (I Know 4 amp/hr isn’t the top dog) has been fine for me. Moreover, I let a buddy, who is a mechanic borrow when his compressor went down. He used it for a few days and no problems with the batt life. Led light is always handy. It doesn’t have the 3 speed transmission like the newer model, but the trigger is sensitive enough, I don’t think it needs it. I’ve used it to yank lugs crossmember bolts, and body mount bolt on a 2004 Tahoe I bought for a winter beater (rust protecting it currently). The tool has not struggle with any of it. Also a nice tool to carry around with you for long trips. Make quick work out of changing a tire. If you’re working on semi-trucks, heh, or battle tanks everyday, this might not be the tool for you. But for common work, it is more than adequate.

    needed MORE POWER this has the power to meet my needs and more the battery life is great and the value makes it worth the money so it doesnt hurt so much when you pay since you get what you pay for 👍👍👍👍👍

    I recently started doing roadside assistance work. Initially I was going to just roll with a breaker bar for changing flats, but I quickly realized this would wear me down fairly rapidly. Harbor Freight has an impact wrench for the same price with about 3x the power (approx. 1200 ft./lbs. torque), and I am sure it is a fine quality tool there, but I have always preferred DeWalt. Anyway, I was initially concerned that 400 ft./lbs. would not be enough for certain stubborn lug nuts, but so far not even remotely an issue! It may also be a blessing in disguise having less torque, as this may prevent over-torquing of the nuts (I’m NOT a mechanic, so take this opinion accordingly lol). Battery life has been simply amazing….I have yet to see loss of power, and I am going into my 3rd full week of use. This kit comes with an extra battery also, by the way. SUPER PLEASED with my new tool for making tire changing a BREEZE!!

    I first purchased a 20v 1/2 impact that had great reviews. When it arrived I tried it on a crankshaft bolt and after 2 minutes the bolt did not budge. I was extremely disappointed and so I returned the impact gun. I did some research and all fingers pointed to the 20v Dewalt brushless 1/2 impact. I was skeptical when it arrived. I charged the battery and attempted to remove the bolt. All I can say is WOW! It broke lose in a split of a second. I was very pleased. I was so excited that I wanted to find more bolts to test it on, but no luck at the moment. I will update more as time passes.

    I have been using this tool for about 3 years to change tires on the race car. It travels with us in the race car for the Baja 250, 500 &1000. It is durable and the battery last all day long with hard use. I love the light that shines when you pull the trigger and the test button that shows ho much battery is left. Keep a punch or small screw driver in the bag to help release the sockets and use only impact sockets.

    I priced this at Home Depot 1st and thought $299 was a little high so, I checked here. It’s $10 cheaper here AND I didn’t realize until it arrived, but, this package comes with 2 batteries, whereas, the HD set only came with one. It was a win/win. Buy with confidence

  8. Amazon Customer

    I have recently purchased this item and it TRULY KICKS BUTT. …. I am a automotive technician and work for a dealership and use this tool daily, I work on jeeps , dodge 1500, 2500 trucks and this tool pulls the lug nuts off the wheels with ease. This is a great tool and will always make sure I have one in my tool box and family vehicle in case we ever get a flat tire. EXCELLENT JOB DEWALT ,,,,,,KEEP THIS QUALITY COMING ,,,,NEXT WE NEED A 3/8 CORDLESS RATCHET ON THE MARKET TO GO WITH THE DRIVER AND 1/2 IMOPACT TOOL, AND 3/8 GUN ….

    Well i just got it yesterday and saw all the reviews and even though i was a little off put by some of the ones claiming it didnt have torque ( i doubted it, i have a few dewalt tools in the past) but this one did the job fast, easily and quietly.Im coming over from pneumatic tools so i was pleasantly surprised to see how easily this thing slapped the nuts off my old chevy, making the job ridiculously easy and clinical feeling.ASE certified mechanic for over 20 years using only pneumatic tools, and this one didn’t disappoint me one bit, as a matter of fact im prob gonna transition over to all dewalt by the time its all over with. Thx Amazon for fast delivery and everything got here in perfect undamaged condition.Its the feel and weight and quality of the sold rubber, the sound of the tool, the quality of the craftsmanship that just lets you know its a top of the line tool. Gonna love being able to whip this out without dragging a 20 pound compressor behind me.Once again a happy customer.

    Lots of power and batteries with “long legs”. I don’t often “need” a tool like this but am happy to know that it is there when I do. I bought it primarily to remove the blade bolts on my tractor’s belly mower. This has the high capacity batteries. The charger renews the batteries from empty to full charge in a bit over an hour. I use these batteries in my Dewalt 20V Max Hedge Trimmers. I can cut all my hedges (about 75 feet) on less than one charge.
