  • Blue collar, but bleed yellow! Unrivaled Power and Precision DEWALT Pneumatic Impact Wrench
Color: Multi Size: 3/8-Inch
I recently added the DEWALT 3/8" Pneumatic Impact Wrench to my toolbox, and I must say, it has quickly become an incredible asset for any project requiring substantial torque and precision. As a seasoned DIY handyman and amateur automotive mechanic, I've had my fair share of experiences with various impacts, and this DEWALT model stands out in several key aspects. The performance of the DEWALT 3/8" Pneumatic Impact Wrench is nothing short of Beast mode. Whether loosening stubborn lugs or tightening small nuts, the tool consistently delivers the right amount of torque for the job. The pure air power is nothing like my cordless impact! You may be red or blue blooded, but I believe DEWALT's mellow yellow reputation for producing durable tools holds especially true with this impact wrench. The tough construction and high-quality materials inspire confidence in its longevity. The ergonomic design ensures a comfortable grip during extended use, and the overall build quality reflects the brand's producing of reliable tools. The only minor issue is the heavy weight, which might feel slightly heavy during prolonged use, but I'm sure you're a big tough blue collar worker that is used to industrial machinery. FYI, be sure to get a tight seal on the quick connect fitting! The DEWALT Pneumatic Impact Wrench is soooo user-friendly. The air inlet is conveniently located at the bottom for quick and hassle-free connections, and doesn't need unnecessary buttons or settings. It's a tool that gets the job done quickly and efficiently without unnecessary complications. Considering its performance, tough durability, and ease of use, the DEWALT Pneumatic Impact Wrench offers exceptional value for your dollars. It's an investment that pays off with each use, especially for individuals who require powerful air tool for their projects. The proven longevity of the black and yellow tools adds an extra layer of value to the overall purchase. Overall, the DEWALT 3/8" Pneumatic Impact is a "must have" tool that lives up to the brand's reputation for excellence. Its combination of raw power, accuracy, and toughness make it a essential choice for both professional tradespersons and DIYers alike. If you're in the market for a reliable and versatile pneumatic impact wrench, the DEWALT 3/8" model is a solid investment that won't disappoint! ... show more

  • Excellent tool (works with smaller compressor)
Color: Yellow/Black Size: 1/2-Inch
1/2" drive... I was concerned that my compressor wouldn't run this tool as I needed it to do. I bought this basically to remove a wheel from my car from time to time. My compressor is a 10-gallon, 135 PSI that puts out 4 SCFM at 90psi... I ran the compressor until it shut off at 135psi. Hooked up the impact gun to my 3/8" air hose and it had no problem putting out the needed air to remove 5 lug nuts on my car. In fact, the compressor never kicked on while I removed the lug nuts. This impact gun zipped off the lug nuts with no trouble at all. This gun is quality and power in one unit. I wanted to post info about my compressor size because I didn't see many reviews that talked about compressors used with this tool. If you have a smaller sized compressor similar to mine and you're wondering if it'll work, it will definitely run this tool on lug nuts. Another note is that this came with a 1/4 in NPT male fitting to use with the air gun, however, I always like to use Milton fittings on my air tools. They are high quality, and I never had a problem with any Milton fittings. So instead of using the fitting that came with this gun, I installed a Milton (V-style) fitting. The V-styles are considered 'high flow' fittings. I don't know if this made a difference in how the tool worked for me because I didn't try it with the standard flow fitting that came with it but I think it would be fine. If not you can always pick up a V-style Milton fitting for a few bucks if needed.... I hope this review helps. I recommend this impact wrench for anyone looking for a well built and highly capable impact wrench. ... show more

  • The owner's manual needs an important update ASAP
Color: Yellow, Black Size: 1/2-Inch
To begin, you can't go wrong buying most DeWalt tools - because it (and 3 other companies) make the "best of the best" when it comes to tools. They stand behind their products too. My only complaint with this impact wrench (and similar air tools) is this: A small plastic "thread-protecting" plug is inserted in the air inlet port at the factory...which must be removed before you can screw the included air hose fitting into that port...but this point is NOT ADDRESSED at all in the owner's manual...and some people might not be able to figure that out. As such, the owner's manual should be updated ASAP IMO. Otherwise, great product - fair price - works great for most jobs. ... show more

  • Very nice impact
Color: Factory Size: 1/2-Inch
This impact works great. It’s lightweight and has a quality build, very comfortable and not too big, it’s just right. I bought it for lug nuts. I use it with a Dewalt 6 gallon pancake compressor that is for my air nailer and it works, in case you were wondering if it would. It’s probably not ideal but it works great for small jobs. I used the air fitting that came with it, put a few drops of oil in the fitting and I was up and running. I use it on its lowest setting and it zips the lug nuts off in about 1 second, no hesitations at all. A bigger compressor would be better but for doing all 4 tires on a truck or car this thing works great with my little Dewalt. It’s good to go, great product. ... show more
