  • This type of saw is helpful during the framing phase on a construction site. You can set them up to trim down framing components, wall studs, and also help with the needed angle cuts as well.
  • They can also be used in fence building and roofing to trim down roof materials and fence pieces for a faster and more accurate cut.
  • Plumbers also find them helpful as they can help with trimming downpipe lengths.
  • For the DIYers, miter saws offer quick, accurate, and easy ways to make smaller miter cuts, crosscuts, and sometimes bevel cuts
  • A standard miter saw comes with electric brakes to reverse the flow of electricity in the motor which, as a result, stops the momentum of the blade in like 2 seconds. The brake system makes it very easy to control a miter saw.

DWS709 Vs. DWS779 – What Are The Differences Between The Miter Saws?

Weight and Portability

Weight can come in as an important part of the stability and safety of a machine. Both miter saws well-constructed with a solid aluminum base that provides rigidity and strength. However, DWS709 comes with a compact design structure that contributes to it just being a little over 60 pounds; dimension of 30.8 x 22.8 x 19.5 inches.

DWS779, on the other hand, weighs about 67 pounds and dimension is 2 x 23 x 18.5 inches giving enough stability to cut through the toughest materials. This also makes it pretty difficult to move around.

Cutting Capacity, Accuracy, and Angles

The DWS709 is a double bevel sliding compound miter saw, that is, it can create a bevel angle on both sides. Its bevel extension can be up to 49 degrees to both left and right. At angles 90 degrees and 45 degrees, it can cut up to 9.5 inches and 6-5/8 inches respectively. Furthermore, the DWS709 has 13 positive stops to fix your angle at, to ensure the maximum accuracy.

For the DWS779, cuts 2×16-inch at 90 degrees and 2×12-inch at 45 degrees can be achieved. Its miter angle ranges from 0 to 50 degrees to the left and from 0 to 60 degrees to the right while its bevel angle ranges up to 47 degrees on both sides.

Also, the DWS779 comes with 10 positive stops and a cam lock that enables the workpiece to be secured in the right place at the desired cutting angle and spares you the twist knob –this is a big deal for a sliding miter saw.

Reviews of the DWS709 and DWS779

With so many impressive features, DWS709 allows for a wide range of massive cut capacities. The DWS709 comes with a powerful 15 amp, 3800 rpm motor, powerful enough to deal with any work you throw at it, as a typical miter saw.

Speaking of accuracy, the extra sliding mechanism usually tends to bring in a few engineering challenges which consequently can result in less stability and blade deflection. These two, of course, can do a whole lot to the accuracy of the machinery. However, we are glad to tell you that DWS709 really shines in this aspect as it has all been catered for, even with a few other features that aid its accuracy.

The DWS709 also features a unique fence which can be considered as fair for a miter saw. It means it can offer more support for tall workpieces by extending upwards, say, comfortably support crown molding up to 5-1/2 inches. The presence of a fence clamp also aids a stable work by pinning the workpiece securely in place while you’re cutting.

Who would want to trade ease an of operation for anything else? The miter and bevel adjustments on DWS709 make everything easier. To start with, there are 13 different locking positions at common miter angles, which mean that you will be able to use any of these positions just as you’re setting a miter angle. The reasonably conspicuous angle indicators make it less difficult to read the bevel angles.

 This miter saw delivers more accurate and effortless work.  It is relatively affordable and highly user-friendly.
