About This Product

The Milwaukee M18 FUEL 21 degree Framing Nailer Kit sets the new standard for cordless framing nailers. By leveraging a nitrogen spring mechanism, POWERSTATE brushless motor and REDLINK Intelligence, this nailer provides users with pneumatic performance and the convenience and freedom of cordless power. Delivering the power to sink full round head nails into dense engineered lumbers, this framing nailer enables users to tackle even the most demanding framing applications. To keep users productive and efficient throughout the day, the framing gun fires 3 nails per second with zero ramp-up time, meaning a nail is fired as soon as the user pulls the trigger. Additionally, the cordless framing nailer operates using only Milwaukee's REDLITHIUM Batteries and sealed compressed nitrogen to drive each nail, completely eliminating the cost of gas cartridges and maintenance associated with competitors' nailers. The M18 FUEL 21 degree Framing Nailer delivers the pneumatic performance and durability that professional carpenters and remodelers expect, without the hassle of a compressor and hose or gas cartridge. In addition to the framing nailer, this kit includes one M18 REDLITHIUM XC5.0 battery pack, an M18 and M12 Multi-Voltage Charger, a rafter hook, non-marring tip and a contractor bag.

          Yes I would buy it again
          Great toe nailing, a little heavy, works exactly like an air gun, battery last a while, excellent tool for all kinds of wood framing or carpentry
            I really recommend it
            It's the best cordless nailgun I've seen so far, its a little heavy but works really nice, fast reload, toenails way better than i expected and most important batteries last for a long time it's perfect for all kinds of carpentry I just bought the tool wish I had the bag, I really recommend milwaukee tools all day everyday 👌
              Great tools!
              Throughout the years all the different brand tools I have purchased and used, without a doubt Milwaukee's Quality and styles always on point.

              horrible delivery
              They dropped this product off at my front door completely destroyed. The packaging was so soaked. It fell apart when I picked it up and it didn’t sit out there. I actually waited for him to drop it off and then I walked out there one minute after it was at my front door this is what i received

                    Don't like compressors
                    I use this once in a while so I don't need the compressor version which is WAY lighter than this. This can get old real quickly, especially if working on a ladder but if you need it for a quick job, it's way better than setting up a compressor and hose.
