Commencing our discussion is the dw779 miter saw. As previously hinted, its blade has a diameter of 12 inches, which is ideal for several sawing applications. The sturdy carbide saw runs on a power 15-amp motor of 3800 RPM.

This is an excellent value, as you have power and stability on your hands, capable of dealing with even the toughest woods. The choice of carbide for the blade is reasonable, as it is less prone to breaking or weakening when cutting through hard material compared to steel.

For stress-free use, you will need the DWS779 stand. It is a structure where you attach this equipment for stability and portability when you move it. Unfortunately, this accessory is not included in the package. You buy it separately.


The DWS779 is highly functional, guaranteeing stability and accuracy when in use. For stability, there is a clamping mechanism and double horizontal steel rails. There are also linear ball bearings, which will ensure you have a neat cut and enhance this saw’s durability.

Still, on the DWS779’s functionality, you will appreciate its flexibility. The saw can bevel 0-48 degrees, both to the left and right. For beveling, you have to unlock the saw from the back. It has ten positive stops, allowing you to get the desired angle.


Additionally, it has a precise miter system, which you run via a cam-lock miter handle. You can change the miter angle to 60 degrees to the right and 50 degrees to the left using the handle. The miter gauge has ten positive stops for achieving an accurate cut.

The scales on the DWS779 saw are easy to read and won’t fade due to their etching on a stainless steel surface. You can attach a DWS779 laser unit, which provides a beam that you follow when cutting wood for accuracy.

The saw has several moving parts for effective use. The sliding saw can move back and forth, making it convenient and safe to use. The railings are also movable to accommodate various wood sizes. When not in use, you can lock the moving parts.

For safety, the DWS779’s blade has a cover to protect the user. When you move the blade head, the cover moves in the opposite direction to expose the blade. A provided dust bag collects the dust from the sawing action, enhancing cleanliness in the working area.
