Questions & Answers

Q:I know it states tool only but I thought it would at least come with a battery so it can be used.
by|Jun 8, 2024
1 Answer
Answer This Question

A:  Tool Only means the battery and charger are sold separately. Some users may already have compatible batteries and chargers from previous DeWalt tools. By selling tools without these components, DeWalt allows users to customize their collection based on their existing equipment.

          The nailer performed flawlessly for facing a set of cabinets and Murphy bed I was building. It was especially nice to not having to listen to a loud compressor.

          Very useful
          Very useful, I just left on the side the air hose and use the battery finish gun , fast , and good precision .

          Installing baseboards, I thought about saving money with a hammer and punch to sink nails manually. Glad my wife convinced me to get this. $300 is worth the time you save and the battery power was very convenient. In Q&A some complained on not finding Dewalt nails in the store and how the only ones on shelf got jammed. This was not the case for me. The 16ga Paslode 2” angled nails worked great and I did not have one issue. Maybe they just loaded them incorrectly?

            Can’t shoot nails in oak trim
            I have had this tool for a while. It Jams every project. Oak trim? Forget about it. Pine yeah sure but it’s soft wood.

              One nail in and the firing pin won't retract
              I bought this thinking that it would be a great time saver. Unfortunately, if other nail guns are semi-automatic, this DeWalt nail gun is like a bolt action weapon from the 1800s. One nail went in the trim, then I tried to fire another. The nail gun fired up, lights came on, and poof a small indentation in the trim. The firing pin is stuck in the forward position, and must manually be reset each time. Returning this tomorrow.

                Beyond impressed
                This is my first go at a cordless nail gun, And holly cow is it life changing. The power is on par with air powered and just slightly heavier. Not having to deal with a hose and compressor priceless. Must have dewalt tool.

                  First nail failure!!!
                  As the title described, I had a nail shoot out of the bottom of the plastic magazine on the very first nail. The nail came out an inch away from where it should have. I used a full battery. Read the destructions and everything. I'm buying a ryobe. They don't have the annoying fan

                    Love this battery. Its lightweight, powerful and it will hold its charge. The on board battery charge light is a plus. It will help you get the job done with power to spare. This battery makes your tools easier to carry. Its a power house at a more economical size in both weight and size with plenty of power to for your dewalt tools. I would rate this batteries 6 stars if I could.

                    Not as good as the old version
                    Had the original version of this when they first came out. It was awesome, had it for about 10yrs and it was stolen. Been using this new version for. I've fired maybe 10 clips of nails. Not as powerful, does not sink nails consistently. It's also misfires a few times already. I don't use the maniac feature or bump feature as most people call it so that isn't the reason. They changed some features from the old one and this just dosent stack up. If it's not broken don't fix it.....
