What to Consider When Buying a Sliding Compound Miter Saw


The motor on a compound miter saw is important because the more power means more cutting power. Usually larger, more heavy miter saws have bigger motors. The last thing you want is to buy a power tool that does not have enough power.

Depending on the type of material you want to cut, be sure to check how much the saw’s engine can handle. If you are only doing minimal work, there is no need for a strong engine since you will not maximize the capabilities of the tool.

Blade size

The blade size on a miter saw is important because the different sizes are most optimal for that size of work. The typical sizes range from 8 in. to 12. in. in diameter.

 Larger blades are able to make longer cuts, but if your work does not require a large blade, you may lose some control by choosing the largest size. Be sure to determine which size will work best for you.

Positive stops

Positive stops on a miter saw are set points that are created by the manufacturer. This helps you to quickly set the saw to specific common angles. This reduces the amount of time required to set up the saw at the accurate angle.

For those that mostly cut at common angles, this can be an important feature to look for. Other than that, other miter saws are adjustable to a tenth of a degree for accuracy. It just depends on the type of work you want to perform with your miter saw.


A miter saw cuts at an angle which is great for cutting parts that fit together, such as door frame pieces. If the miter saw is not accurate, these parts will not fit well together.

For all cuts, but especially angled cuts, accuracy is incredibly important. A high-quality miter saw allows you to adjust less and provides hassle-free cutting. Investing in a quality miter saw lets worry less about the accuracy and lets you breeze through your cutting.

Safety Features

When working with a power tool, it is easy to make a small mistake that leads to a serious accident. After all, it is a high speed spinning blade that comes close to your limbs.

Most miter saws come with safety features that help to decrease the risk of serious injuries. Some added safety features include a blade guard or electric brake that serves as an added layer of protection while you are working. Woodworking Safety Rules Every Woodworker Should Know

Main Differences Between DWS779 and DWS780

The main difference between the two Dewalt models is that the 779 model is a single bevel saw and the 780 is a double bevel saw. The 880 also has more additional features for added convenience.

A single bevel saw like the DWS 779 model is great for cutting at all angles. A double bevel saw like the 780 model is able to cut on both sides of your cutting material. While both can technically cut on both sides, the double bevel model allows you to do so without moving the material. Instead of manually moving the material, the tool is able to tilt over to the other side to make bevel cuts. Most people will only need a single bevel saw since it is simple and easy to use.

This type of saw still gets the job done quickly and efficiently. Single bevel saws are also less expensive since it does not have the capability to swing on both sides. The Double Bevel Miter saw is a bit more complicated to use, which can be difficult for some beginner users. If you do need to make a high volume of cuts, having the dual tilt component can allow you to move through your work quicker and easier.

Another main difference between the two saws is the XPS crosscut positioning system. This added feature creates an adjustment-free shadow line that indicates exactly where the saw will cut down on the material. Although this is a great feature that adds to the user-friendliness of the tool, it is not a necessity. You are still able to make quick and accurate cuts without it.

The added capability just adds to the efficiency for users that need to make many cuts. It provides hassle-free cutting that is fool-proof.

A single bevel saw is the most optimal choice for home users since it is a cheaper option and easier to use. You are able to get the same cuts done, it just may take a bit longer since you may need to rotate the material. For users that do not need to make cuts every single day, rotating the material is not much of a hassle. A single miter saw is also usually less heavy, which makes it easier to lug around or store.

A double bevel saw is most optimal for professionals or advanced miter saws users that have a lot of work to get done. Since the double bevel miter saw has the added capability of rotating in both directions, it increases the efficiency by a considerable amount. For professionals that need to cut many angled materials, this type of saw can make your life that much easier.

Choosing the Best Miter Saw for You

When choosing the best miter saw for you, be sure to keep in mind the type of work and the level of work you are doing. Single bevel saws are better for home use since they are lighter, cheaper and get the job done.

The double bevel saw is better for professional use, but it is easy enough to use by any level of user. If you do need the added capabilities the DWS780 has to offer, it is a great choice to invest in a high quality tool that can last you a long time.

If you have no need for some of the extras, the DWS779 is a heavy-duty tool that provides accurate and reliable angled cuts.

While all the extras may sound great to you, you may not be able to maximize the saws use, if you are a home user that does not need to make bevel cuts every day. They are both great quality saws, it just depends on your needs.
