Questions & Answers

Can you plug into 120v if needed
ByAug 14, 2026
1 Answer | 
Answer This Question

No, the DCS781B is cordless. It will only run off of the 60V batteries.

    Does this specific saw come with Dewalt XPS system
    ByMar 20, 2026

    Answer This Question

    Yes, it does. DeWalt changed the name to Cutline but is the same as the XPS positioning system.

    By|Jun 1, 2026

      No, the DeWalt DCS781B miter saw does not include the XPS system. Thank you for your question.

          The approximate weight is 51 LBS.

            Does this have an adjusting RPM switch? To lower rpm for a metal cutting blade?
            ByMay 12, 2025
            1 Answer | 
            Answer This Question

            The Dewalt model number DCS781B does not have an RPM switch to adjust the speed for a metal cutting blade. It operates at a no-load speed of 3800 RPM and is designed for professional applications with a 60V MAX* battery system

              Is the 120v max model no longer in production? I guess il have to spend my money on a different brand miter saw that offer cordless and corded combo

              Answer This Question

              Yes, the 120V Max Miter Saw has been discontinued

              By|Mar 21, 2025

                There is a plug-in adapter that slides on to the battery mount. You can use this saw with a battery or with the 120 battery adapter.

                  Can you add wireless tool connect like the video above shows? It is the European 54v saw in the video which has it to connect to 60v/54v dust extractor you sell. Why Europe gets that feature but us in the US does not is stupid. Can this feature be added

                          Bought this because they had a bogo deal for a battery a man, this thing is phenomenal. What I love is how much quieter this is during start up than a trad miter saw. Cuts trim like butter, cuts PT 4x4s like nobody’s business. I love this thing.

                            This thing is great. It just takes a little while to put together. Make sure you read the instructions first. So you don't hurt yourself when you're putting it together. There are some zip ties that aren't supposed to be cut until you are ready to use it. Overall, it cuts great and the battery lasts a long time.Definitely on the pricey side, but for me, the versatility was worth the money, I got the stand that roles.And I could take it anywhere.I want

                            Not reliable at all
                            This is the worst saw ever... it doesn't hold the bevel at all. Two of them broke in three months of using. No tool connection, dust collection is very poor. This saw may be just for framers, but not for finish carpentry for sure. I would not recommend this saw for the following reasons: 1: It doesn't hold the bevel. You may cut just straight cuts with it. 2: The quality of that saw is very poor. You need to adjust it every two weeks. 3: This saw is not reliable at all; mine broke for the second time. I've been using it for six months, and for finish trim, I had to buy a different saw..

                              Waste of a lot of money
                              I bought this saw with stand and two batteries about one year ago. It’s still in pristine condition other than it all of the sudden stopped working in the middle of a job I am doing. I found out that no one repairs them locally and the batteries pooped out also. Both batteries are not charging all the way. It’s extremely frustrating because I thought I was paying more to get reliability. But now realize it’s another cheap tool. Don’t waste your money on this system. Looks pretty is all….

                                Unreliable, 7 out of 10 that I've purchased no longer work after less than a year!
                                We have bought 10 of these at the company I work for in the past 2 years. Seven of those ten saws have died within a year of usage. All having the same issue where it will work fine and then all the sudden you go to make a cut and it's dead. Battery is fully charged and works in other tools fine. Dewalt claims they are not aware of any issues with this product. Well the switch is faulty, it goes bad and has to be replaced. Of course you can't just buy the $10 part, they make you buy the entire electrical system for nearly $300. I was able to get 6 of them repaired for free under warranty. Of those 6 saws, 4 of them died again within 6 months. This thing has issues, do yourself a favor and get the corded version. If you have to have cordless then go with a different brand. This thing is not going to last like a dewalt 12" miter saw should. Buyer beware! If you plan on using it daily or for a long time, do not waste your money on this tool. Your warranty expires after a year and then you have to pay $360 every time it dies. It's only a matter of time! You've been warned!

                                  [This review was collected as part of a promotion.] This saw is amazing. All the features and power without the cord. The cut line light works far better than it does on my smaller 20v version. Table turns smoothly. Fences are nice and high. 9ah battery lasts me pretty much all day cutting trim and baseboards. I can’t really find anything yet that I don’t like about it. Just an all around great saw
