    A:  There is not an adapter that has been tested and recommended for use with this saw by the manufacturer DEWALT. Blades that do not match the mounting hardware of the saw will run off-center, causing loss of control

          they must not check returns
          I just picked this up tpday for a project and when I opened ghe box its an old beat up tool with marks all over it. So clearly someone scammed them out of a new tool. They should probably check returns better cause now I have go drive a half hour to get this fixed

            My favorite circular saw to date
            I purchased it for a deck remodel project at my bother house. We removed the old deck boards and installed synthetic boards as well as correcting some sags and age related issues. This saw cut through all the old deck boards and all the new synthetic boards without issue. We used up two 6 hour batteries in the process which surprised me as I expected to go though many more. What I like best is the reach and the way it feels in your hand. Dewalt got this one right in so many ways.

              Dewalt brushless and battery only no charger no bag
              What the receipt picture shows was not what i bought it only was the drill and battery. I just got home, purchased around 9:30 from Salem, Oh and the battery doesnt work or charge and the drill had a screws almost all the way out of the brushless drill. I was in a hurry like always bc they were about to close the store so i didnt notice the backed out screws that hold the drill together! The drill seems to work with a battery I already own after I reassembled it but havent tested its performance due only seen it turn and light come on. Not sure why it wasnt tested before being put on the self for sale!

                  Dewalt Atomic 20 volt Compact Driver
                  This Dewalt Atomic 20 volt compact driver is a powerful driver. It came with two batteries which is awesome. The clip holster is great too. The quality of the driver is better than my neighbors Milwaukee that i have tried.

                  Very handy and easy to transport.
                  I'm super happy with this tool. I build a small fence using this saw to make all the cuts, battery never run out and the cuts where perfect. I even cut the 4 x 4 posts. Super handy and easy to use. Light weight. The only thing I don't like is the safety lock, it was kind of a pain to get used to it, but I guess is good for the use of the saw.

                    Stopped working after 3 months of light use
                    Driver stopped working after 3 months of light use, not a great experience. It stopped driving in forward and then stopped driving in reverse.

                      I cannot say enough good things about this saw. I just purchased this and I'm using it to redo our back deck. I'm mostly cutting pressure treated 5/4 x 6 decking and 2x's. I didn't initially see that it comes with a blade so I had purchased a Diablo construction blade which I'm using. I use a 5 ah battery with EXCELLENT results. It's weighted perfectly and the feature that I like the most is the trigger safety. Instead of being a button that pushes in, it's a lever that pulls down slightly; it's a very natural motion when you're holding the tool to cut. This is a very quiet, accurate and efficient tool, especially at this price point! Trust me, you want this saw!
