    • Great tool
I didn't know what I was missing before I bought a 12" miter saw. The Dewalt 780 is well made and very accurate but also quick to change from cut to cut. My saw needed some tweaking on the pre-set stops but that was an easy thing to do. After that it was ready to go. The fit and finish of everything was good. The slides are a little rough at first but seem to wear in over a little bit of time. That was a concern at first and other reviews mention it as well but it doesn't seem to be a problem now. The sawdust bag works okay but has very limited capacity. The shadow light also works very well. Mine is slightly off (maybe .005) but after using it for a while it's easy to compensate. It's a great feature. I haven't looked at the manual to see it that's adjustable but it's only off by something like the width of a sharp pencil line and once you've adjusted yourself to that you can split a pencil line. The motor torque is surprisingly strong at start up. A soft start would have been better but, again, it's a very minor issue on a great saw. Purists and professionals may not love this as much as me but it's fast, easy and accurate for my needs. My radial arm saw hasn't even been turned on since I got this 780. I also bought the Dewalt stand. It works great too. The work support adjustments require some tweaking to get perfect when there's a need to change them but it's easy enough. If you have a jamb level it's REALLY easy. The extension arms work well on long material and stay pretty level even when extended way out. I've added this mini review because it's such a good companion piece with the saw. If this was lost or stolen I'd order a new one immediately. It's just incredibly fast to work with; it's easy to change the setups and the cuts are very nice. I did buy a better blade for trim work but the stock blade works fine for less delicate pieces. ... show more

this tool is more than that its a work of art. It made me look like a pro with perfect precise cuts, SO far im just so impressed. Dewalt has made a joke out of setting this saw and the cart that they made for it, a caveman could do it/1 lol

    • An Absolute Treasure
I was in need of a new saw that would replace an older 12" Ryobi chop saw (toy). I also wanted to eliminate the remaining nagging need for a less accurate radial arm saw. I had already replaced the need for overhand dados with a good router and the needs for most finish work with a highly accurate sled and fence on my table saw and needed something that could perform as a chop saw but also had the depth to crosscut a decent depth for stairs, flooring and really wide trim and finish pieces that ould be awkward to cut on the table saw no matter the setup. I have not noticed ANY of the problems mentioned by some reviewers and the rather uniform form of those complaints leads me to believe some of them at least may be paid guerrilla commenters. The saw was checked right out of the box with a dial gauge and was dead on. The factory blade was not bad actually. It cuts cleanly as a general purpose crosscut blade but will obviously not last as long as a higher quality blade will or cut quite as cleanly as a finer toothed blade will but it cut through a set of 2 x 12 pressure treated for decking stairs very well; it also cut through some clear grade pine shelving without splintering the edge of the cut. I will still change the blade for really fine stuff. Also the saw didn't seem to bog down in the least going through the heavy pressure treated wood. The XPS system is a freaking dream to use and such a vast improvement over any of the laser systems I've seen or used. If you bring the blade down almost to the wood you get a razor fine line where the saw will cut so you know exactly where the blade is going - no more adding a 1/16" or an 1/8" and the gravy is that you don't need to spin the blade up while your face is closer to the wood and blade to line the cut up because the XPS system is independent of the blade - just remember to turn it off when you're done using the saw. or you'll kill the long lived LEDs before their time and waste expensive electricity. The dust bag is a joke as all dust bags have always been on all miter saws since they first came out. You can probably hook it up to a shop vac and be fine. The blade does quite a powerful job of chucking the saw dust out of the cut area giving it some momentum going into the dust chute. I have been hooking mine up to my roll around 1hp Grizzly dust collector though and love the performance and would say the claims about the dust collection of the hood behind the blade of this saw are not very much exaggerated. In fact I made a few cuts through some of the scrap 2 x 12 material without the dust collector or dust bag and received almost no dust in front of the saw. (It will shoot it out about 15-20 feet behind the saw though) I used a 1 1/2" to 4" Fernco coupler (cost like 4 bucks) on mine and a 6" length of 4" PVC scrap (the white stuff) to connect this to the 4" hose from the dust collector and it works like a charm. The bearings. Many are the whinings about the bearings and the accuracy at full extension - especially when using the back fence to be able to cross cut 16". The first thing is that they stick or are hard to move. The first couple of passes out of the box and the bearings did in fact seem a bit stiff. There is little to no lube on the bars right out of the box as the bearings have not been slid over them. A few passes and they loosened up a bit; a little machine oil and they flew. The only time they seemed to bog after that was when I was making some test passes through scrap with no bag or dust collector hooked up to see how much dust was actually being captured by the blade hood. I'm sure this just accelerated what would happen slowly anyway but dust caked on the bearing did succeed in bogging up the glides. A simple wipe down followed by a few squirts of machine oil and I was back in business. That is simple, common sense maintenance though and shouldn't be held as a ding against the saw. The other popular complaint is the accuracy at the full 16" cut depth. I made and installed the sub fence by following the instructions in the manual and made some test cuts. It bears to mention that 16" wide pieces of lumber of any length can be quite unwieldy and should be clamped before cutting - both for accuracy and for the love of our fingers. There was less than a 0.002" difference between the near side and the far side of the cut. That is far, far less than 1/64th of an inch and not noticeable in any finish work and I dare say a good bit closer to perfect than any of the cuts made on mass produced furniture. I've since used the saw to make 16" deep serving table made up of glued up pine panels and it is dead on square and level. As far as I am concerned that is near enough to perfect as makes no difference and about as close as you can get with any woodworking equipment. I love this saw and see many years of use in it if taken care of properly. I did find it kind of amusing that the Ryobi branded stand I had purchased for my older Ryobi 12" miter saw required me to make an adapter plate out of plywood to fit the Ryobi saw to the clamps that hold it on the stand but the Dewalt fit right on the same clamps with no issue like they were made for it. ... show more

    • Great Accuracy, Shadow Light works well
I bought this to replace a Metabo saw that frankly was an ergonomic disaster, nor could the saw maintain fixed stop points.. The settings were accurate straight out of the box. The shadow line works well, I've had previous saws that used a laser light that frankly didn't last a year before going dead. Hopefully the shadow light lasts longer. The only flaw in the saw is the dust collection system, DeWalt placed a soft rubber seal at the entrance to the dust collection system, it tends to actually block the entrance (I'm connected to a 2hp dust cyclone, so it pulls a large volume of air. ... show more

    • Excellent saw, difficult customer service!
We buy Dewalt whenever we can, and this saw is excellent, very sturdy, and right on the money for miter corners. The size is great, and it is not too heavy. I can move it easily. The cast aluminum fence if very heavy duty. The reason I am giving it 4 stars, is customer service. I needed to speak to customer service about a small issue. The person on their help number had difficulties understanding my question (it was simple). They finally gave me the number of the service center "closest to my location". The service person said I could bring in the saw, and asked where I am located. I said WV. They were in CA.....When I said the enclosed tool would not loosen the screw on the blade (as the manual stated it would do most easily), he said, well they used an impact wrench....So, I drove back to Lowes and purchased an impact wrench to change the blade....As I said, I love the saw, but my experience with their customer service was not stellar. ... show more

    • Good saw for the money
In reference to other's comments: There is really no such sliding saw that has zero head deflection if pressed hard enough. Learn to use the saw with finesse and don't force it. It works just fine. For perfect stability get a radial arm saw or a saw buck. Every tool has its little quirks but this one has very few. The good: 16" cross cut. Thumb lock works great. Easy to adjust the miter detentes to dial them in perfectly. Power! Pretty smooth glide. Nice light. Easy to bevel. (My last saw the Hitachi 12" was really clumsy to bevel) Love the bevel stops that pivot out of the way if you want them to. Very handy idea. Fence has a durable feel. Excellent Teflon glide for the miter base. Weighs less than other 12" saws and is way easier to carry than my old Hitachi. The "oh well": The glide rails do stick out the back so it takes up a lot of room on a bench. The blade is not so good for finish work but then complaining about the bade a saw comes with is kinda like complaining that your new car came with bad wiper fluid. Just replace it. No big deal. The included blade would be great for framing lumber though. I recommend staying away from a thin kerf finish since it's more likely to wobble on a 12". Get a good 100 tooth full kerf. The bad: I have not found anything bad about it just yet other than be careful in regards to "pull up" of the work piece since the blade plunges so far down into the base. But it's no big deal if one is careful. It's actually no big deal to simply not plunge the saw all the way down. Or, one could adjust the plunge stop up and then install a sacrificial fence. If you need to have the full 16" crosscut just remove the sacrificial fence temporarily. No saw will do absolutely every task without some modifications. For instance if you are one that can't figure out the math in order to cut crown flat (shame on you if you call yourself a carpenter) then build a sled jig with fence that is sized for the crown your working with and cut it standing up. Heck back in the old days with radial arms we had jigs for everything. In conclusion: Good saw for the money, smooth and powerful, be careful of "pull up" if you have the grace of a neanderthal , buy a nice full kerf finish blade while your at the store getting your saw. Google up some you tube videos on making sacrificial fences and jigs. ... show more
