Rated 4.7 out of 5 by 91 reviewers.
Rated 5.0 out of 5.0 by So impressive I had to buy 2 I am just a homeowner and after using this saw with the 4.0 Ah batteries, I had to buy a 2nd one. Saw is very easy to set up. The plate is SOLID, no play at the rear depth connection. Saw is heavier than some, but the extra weight is offset by GREAT balance IMO. This saw rips through wood wether ripping or crosscutting nothing holds this saw back. I was able to cut tons of 2x4's as well as ripping OSB sheets on a single battery charge. Nothing holds this saw back. On my 2nd one I have the 40 T blade and the saw handles it like nobodies business. This saw should be your MAIN tool. It certainly is mine. I only use my corded saw for major work this saw cant handle. Which isnt much (long bevel cuts in 2x4 stock) The markings are accurate. Easy to cut straight. Worth every dime and then some. Better than some more expensive corded saws... April 2, 2014
Rated 5.0 out of 5.0 by One Word "Butter" After shearing through the cord of my beloved 'other' brand. I decided to go cordless with the Dewalt 20v. I read reviews on the internet and also purchased a 40 tooth saw blade. The saw cuts like "butter", and leaves a baby smooth finish. The best part of all is; I just reach into my tool bag and start cutting, NO extension cords. This fact alone makes this purchase a winner!I am so impressed that I am soon ordering the 20v jigsaw soon. (don't tell my wife). July 28, 2013
Rated 3.0 out of 5.0 by Great saw overall, best for Lefties. Overall, this is a good saw. Pair it with a 4.0 Ah or 5.0 Ah battery and you've got a work horse. I love being able to pull it out of the bag and start cutting. Like other reviewers have stated, it rips through 2x4s like butter. The first task I put it on was cutting 4x4s. Of course I had to take 2 passes to cut all the way through, but for a cordless saw, I was impressed at how many passes I was able to make before the battery died. My only complaint is its set up/ configuration. This saw would work much better if I were left-handed. Since I'm not, I find it awkward to use. I wish DeWalt would make this same saw with the blade on right side of the motor. April 10, 2015
Rated 5.0 out of 5.0 by Unplugged!!!! Finally a cordless saw worth toting around. I do new construction and power is not always available. Loading and unloading a generator by myself is not an attractive option for small to medium sized jobs like forming concrete porchs and sidewalks or light framing. My 9 year old Nicad was OK and beat hand sawing but having already bought the new 20V drill and impact driver I decided to give this circular saw a try. WOW! What an impovement. May 4, 2014
Rated 5.0 out of 5.0 by HD saw for a cordless Saw is heavy and has plenty of power. Also like the 6.5" blade vs a 5.5". So far no complaints. April 21, 2015
Rated 5.0 out of 5.0 by Amazing tool!! This line of 20v tools is absolutely amazing. I have the hammer drill, saws all and circular saw. The battery life is exceptional, I just finished building 220 ft worth of wood picket fence, these tools were just what I needed. I recharged the batteries only twice and completed the project. Well worth the price!! August 19, 2014
Rated 5.0 out of 5.0 by Worth every penny Good saw for being cordless. Plenty of power and a smooth cut!! March 24, 2015
Rated 5.0 out of 5.0 by Do it your selfer Love it has plenty of power and not heavy like some other models. March 12, 2015
