Description

Take a tough miter saw applications with this 12 in. Double-Bevel Sliding Compound Miter Saw. a 15 Amp motor and integrated XPS crosscut positioning system for adjustment-free, accurate cut line indication, this tool is designed with a durable stainless-steel miter detent plate with cam lock. From the Manufacturer The DEWALT DWS780 12-inch sliding compound miter saw, has been designed to be precise and accurate enough for fine woodworking, yet durable enough for framing and deck building. The DWS780 is ideal for a variety of end users, including cabinet makers, trim carpenters, framers, installers, and many other professional contractors who require a product that delivers the accuracy, capacity, durability, portability, and ease-of-use that this saw offers. For visibility and accuracy when cutting, this saw features the XPS LED light and cut alignment system that casts a laser-like shadow on the work surface, showing users where the blade will come in contact with the material. Since it does not require recalibration over time or when changing blades, this alignment system can be more accurate and durable than traditional laser guides. The saw’s dual bevel system includes the ability to bevel right and left from 0 to 49 degrees with positive stops at 0, 22.5, 33.9, 45, and 49 degrees in both directions, as well as a high visibility bevel scale. The saw also miters 60 degrees to the right and 50 degrees to the left and features an adjustable stainless steel miter detent plate with 10 positive stops, allowing for fast and easy adjustments. A cam lock miter button allows users to lock angles between detents for versatility on the jobsite. The saw features a powerful 15 amp motor that delivers 3,800 rpm. For convenience, the power cord is routed through the rail in the back, eliminating interference with the slide. Additionally, the saw offers an industry-leading combination of cut capacities, which includes 6-3/4 inch vertical capacity, 7-1/2 inch nested crown capacity, 13-7/8 inch horizontal capacity, and exclusive back fence design that cuts up to a 2 by 16 at a 90 degree angle and 2 by 12 at a 45 degree angle. To simplify and maximize vertical cutting capacity, the unit includes a rail lock latch for holding the head away from the fence.

Well been wanting to upgrade from 10" to 12" Miter Saw for sometime now and after watching videos and reading reviews I finally settled on the Dewalt 780. I have been using the Skil Saw 10" which was a lot of power for the saw but it lacked the range on cutting angles and bevels. Out of box needed nothing to put together and only needed to make a 1/4" adjustment to level inside my miter station. The little jump it has when pulling in trigger will take some getting use to, but it was square and no wobble in blade. First cut using the 60 tooth blade installed cut like butter, but will be replacing these with an 80 and 100 tooth for fine cuts later. Very pleased and so glad Amazon has the monthly no interest way of getting machines for my shop with out having to pay full price for item in one lump sum. ... show more

    • Dewalt miter saw 12 inch with slide
Best miter saw I ever purchased. This miter saw throws down all the tricks. If you know how to use it there’s nothing that it won’t do. The quality of the cut. In the functionality of the equipment is worth every penny you spend on it. Well worth the value. Worth purchasing the miter table to go along with it gets a little heavy carrying it around. ... show more

    • 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

    • Torque kick can be Surprising.
I bought the saw as an upgrade to the Kobalt 12" double compound sliding miter saw whose motor (not replaceable) burned out. Although the Kobalt was poorer in overall quality and alignment repeatability, it had a number of common-sense features that are missing on the almost double priced DeWalt. The most significant feature being blade gearing that reversed the motor torque from the blade torque naturalizing torque kick (jump). Overall the saw is quite good quality. Machining of the platform is excellent although the fly-cutting on the fences are coarse. The saw does not have an alignment laser, but has a nice worklight instead. Since lasers are seldom accurate for precision cuts, for me it isn't a problem, Several features are missing such as a standard size shop vac sized vacuum attachment and an undersized sawdust collector - a complex poorly performing and really mickey mouse setup. Because it extends out the back of the slide instead of near the motor frame, the saw has to be placed well away from a wall to prevent hose interference. Since it is not the standard shop vac large size, an adapter and right angle adapter are needed to use anything but the dust collector bag which catches about 50% of the dust. One feature I like is the ability to deep cut vertically which allows larger wood to be cut. In addition the slide is longer than many others allowing wide boards to be cut. However I did find that the slide glides easily when the blade is up and is stiff under load. I'm not sure this will improve as it is used. However there are three important design issues that, in my opinion, could make it difficult to control. The first and most severe is torque kick. Because the motor and blade turn in the same direction, the kick adds and handle and blade kick up significantly when turned on and down when released. It is strong enough that if you are not expecting it, the force will jerk it out of your hand. You can minimize it by ensuring the blade is fully up against the stop when turned on. However, again, the entire saw will then jump if being used as a portable and not screwed to a base. This can dislodge the work from the fence and platform causing mis-alignment of the cut.. The more dangerous problem is when it is switched off. When the switch is released, the stopping torque will force the blade down. If the blade is not high enough off the work, or fully down it can be driven back down into it. This can result in either a ruined piece or the piece being grabbed and thrown. It is powerful enough to wrench it out of a clamp and certainly out of your hands if not ready for it. I've found that leaving it in the lowered position is best, The blade brake stops it pretty fast so even if you are cutting and repeating, you can develop a technique with practice. Another design deficiency is the lack of topside release clamps for the two work extensions on either side of the bed, which are more like handles and are installed with a t-bar and wingnut under the pivoting base which has to be removed from the stand to access - they are essentially useless. They are also too short to be of use. A third design deficiency are the rear and underneath location of stops for compound cuts on crown molding laid flat. I recommend using the optional crown molding stops and cutting simple 45 or 22.5 deg. angles. Before choosing this model of DeWalt saw, I recommend checking out model or bands. ... show more
