          For those looking for a professional grade miter saw, the DeWalt DWS780 12-inch Double Bevel Sliding Compound Miter Saw is the saw they want.  This model is by far one of the best miter saws DeWalt has produced.  Remaining portable with a modest weight of 56 pounds, the DWS780 offers big boy muscle in a little guy body.  With a linear ball bearing rail system, this saw can help to improve your productivity on the jobsite.

          Best Features

          The best feature about the DWS780 is the Integrated XPS Cross Cut Positioning System.  Instead of using a laser to show where the blade will make contact with the material, a light that is positioned above the blade cast a shadow onto the work piece that will show the width of the cut.  This helps to eliminate the trial and error guess work when setting up cuts therefore saving on material.

          The advantages of the DWS780 are numerous.  Along with the XPS cross cut system, it also features a highly efficient dust collection system that captures up to 75% of the dust generated while making cuts.  The equipped back fence can handle material up to 2-inches by 16-inches at 90 degrees and 2-inches by 12-inches at 45 degrees.

          The 10 positive stops on the stainless steel miter detent plate insure quick and accurate cuts at either 60 degrees to the right or 50 degrees to the left.  An oversized bevel scale helps to make fast adjustments.  An additional feature is the cam lock miter handle that includes a detent override that enables fast and accurate miter angles.  With all of these features, the DWS780 still weights a modest 56 pounds which makes it portable from shop to site.


          One disadvantage, depending on the user, is the motor size.  Even though the DWS780 is considered a professional grade miter saw, it still has the same 15-amp motor as the smaller DeWalt models and produces a 3,800 rpm no load speed.

          This means it will have the same issues as the smaller models with bogging down when cutting tougher materials.  The only other notable disadvantage is the space required.  With rails that protrude from the back while in operation, the DWS780 requires a fair amount of space in order to operate it.  But then again, so do most saws that use a rail system.


          Despite the very few flaws with this saw, if you are a professional that is looking for a high end saw that can increase productivity, the DWS780 is for you.  However, if you’re a hobbyist that wants a quality miter saw that help make your woodworking projects simpler, then perhaps not.

          The only reason for this is the price tag.  At $500.00 and up starting price, it would be quite a while before the DWS780 earns your money back for you and for a weekend woodshop warrior, you can get great results with the more cost effective smaller models while still maintaining a high quality tool. A couple models that you should check out are the Hitachi C10FCE2 and the DeWalt DW715.
