Rated 4.8 out of 5 by 89 reviewers.
Rated 5.0 out of 5.0 by Quality saw!! I'm just a DIY guy and I enjoy quality! I purchased this a year ago with the bonus collapsible stand and have used it many times from cutting trim and crown to normal lumber. The 60T fine blade that comes with it produces a nice smooth cut. I also purchased an 80T blade for more precise work. The locking mechanism for the angles is nice and precise. The dust bag works well but still isn't mess free. I'm not too big on the light, I would of rather seen a laser; but it's still a good guide. Overall its a great addition to my tools and I recommend this to anyone! August 3, 2015
Rated 5.0 out of 5.0 by Amateur carpenter This saw has good solid construction and offers a useful selection of adjustments to help with those accurate cuts. It's a little heavy for lifting but this the only drawback I have experienced with this saw. I would give this tool a high recommended! October 22, 2014
Rated 5.0 out of 5.0 by Great Miter Saw Great product easy to use,easy set up, stand for saw makes it fantastic to move around April 4, 2014
Rated 5.0 out of 5.0 by Simply the best! I am a beginner and this is my first miter saw but when I use this machine I feel like a pro cause it's so easy to use, so accurate just make me want to do different project one after another. And it came with free Dewalt stand. I love this miter saw! October 3, 2013
Rated 4.0 out of 5.0 by excellant saw Hardly any assembly, straight smooth cuts, angle cuts fir together perfect. Great for decks and other multiple uses. January 12, 2016
Rated 3.0 out of 5.0 by good saw while it lasts!! first id like to say I am a professional finish carpenter and use my saw every day. I started my business 5 1/2 years ago and unfortunately have now already gone through 2 of these! The first one lasted 2 1/2 years before the brushes went out in the motor and had to wait 3 months before I got that back. But since I have to have a saw I bought another one while it was being fixed under warranty. When I got it back I sold it, but 2 weeks ago my newer saw has the same problem with the brushes in the motor and h.d. just called and told me since im 6 months over warranty I have to spend another $176.50 to have them replace the brushes! so in 5 1/2 years I have now spent close to $1300.00 on these saws!! I have numerous dewalt tools that I have boght from h.d. and will not be buying anymore. if you aren't planning on using this saw very much, im sure it will last longer. but for people like me who use it every day for business, id look else where! Just my two cents December 16, 2015
Rated 5.0 out of 5.0 by Miter Saw Great saw! Smooth and very powerful. Chose this model over the rest because it's ability to cut wider and taller pieces of material. And the light that shines from behind the blade which casts a shadow onto the workpiece as a guide is much more accurate than the traditional laser. December 29, 2015
Rated 5.0 out of 5.0 by This 12" compound, dual bevel, sliding miter saw is the best I have ever owned as a Pro In my picture you will see my new DeWalt saw in action. My Builder likes it as much as me. He even commented on the LED light marker, " I have never, ever seen any other saw that has a perfectly accurate light marker as this one" Nice... January 14, 2014
