Can the DEWALT 12-Inch Double Bevel Sliding Compound DWS779 cut 2×14 lumber at 90 degrees and 2×10 at 45 degrees?

We picked it for a full review because its listed lumber capacity resolves the title question directly.

For that answer to hold in your setup, the board still needs enough fence clearance and slide travel to sit flat and move through the cut path. A compound miter cut uses both miter and bevel angles, so the 49-degree bevel range and 60-degree right miter swing matter when you move beyond straight crosscuts.

DWS779 cutting capacity, bevel range, and dust collection

The DWS779 is a 12-inch sliding miter saw with a 15-amp motor and a 3,800 rpm blade speed. That matters for a miter saw buyer because wide stock can bind or tip if the throat, fence, or support setup is too small for the board. Its lumber rating is the key figure here: it cuts up to 2 x 14 dimensional lumber at 90 degrees and 2 x 10 at 45 degrees. Nominal lumber dimensions are the labeled sizes, not the actual finished size, so the real board is smaller than the name suggests. The saw also has a double bevel, which lets the head tilt left and right instead of forcing you to flip the work for opposite-angle cuts. Its dust collection captures over 75% of dust, and the included dust bag gives you a place to start if you want cleaner cuts.

What to Check Before Buying the DWS779

• Measure the widest board you plan to cut, then compare it with your own fence clearance and support setup.
• Check whether your longest boards can ride the slide without the cutoff or offcut binding at the end of travel.
• Decide whether your 2×14 stock will sit flat on the fence or needs a sacrificial fence or extra support.
• Match the cut to the angle: straight 90-degree cuts and 45-degree cuts are the two lumber cases this listing states.
• Make sure your shop can handle a corded 120-volt saw, since this model is not cordless.
• Plan for weight and placement, because this saw weighs 56 pounds.

Where the DWS779 Fits Among Sliding Miter Saw Options

The DWS779 suits you if you want a corded 12-inch sliding saw for large trim, framing, and routine dimensional lumber cuts. Buyers who need cordless portability should look elsewhere, and buyers who want a lighter saw for small trim work may prefer a smaller blade size. If your work centers on wide boards, repeated angled cuts, and a double-bevel layout, this format makes sense. If your projects stay small, the extra capacity may be more than you need.

Choose the DWS779 if you want one saw that handles 2×14 at 90 degrees and 2×10 at 45 degrees, plus a 12-inch sliding format for larger cuts. It is a practical pick for you if your setup can support a 56-pound corded saw and you want the wider-cut capacity first.
