A dual beveled compound miter saw is identical in function to a single bevel version, with the addition of the ability to tilt in both directions, that is, to the left as well as the right.
These saws are recommended when you have to go through a comparatively larger volume of crown molding or other kinds of trim workpieces. Making repetitive cuts without having to flip and reposition the workpiece continually can save you a lot of time, as well as effort. If you are a pro, or plan to do a lot of advanced DIY projects, especially involving longer workpieces, dual beveled saws are better than standard compound saws. You may also want to look at more advanced variants like sliding compound miter saws.
Many DIY beginners are not familiar with the comparison of a single bevel vs double bevel miter saw. In a standard or simple miter saw, the saw blade can make two types of cuts on long and thin workpieces:
In these basic miter saws, the saw is always held at a perpendicular angle and cannot be tilted. But they can be pivoted for angled cuts, also called "miter cuts." The saw is attached to a hinged frame, which can be rotated to the right or left to produce these miter cuts. The standard miter saw is a very limited tool, that stands just above a chop saw due to its ability to make those angled miter cuts.

A beveled miter saw can perform two more complex cuts than a standard miter saw. The four basic cuts this type of saw can perform are:
Thanks to the ability to perform compound cuts that involve miter and bevel cuts, a beveled miter saw is commonly called a compound miter saw. In this type of saw, in addition to the ability to pivot, the saw blade can also be tilted to angles between 0-50 degrees. These saws have more utility than a chop saw or a basic miter saw.
A basic compound miter saw has only one bevel, meaning the saw can be tilted only in one direction, usually to the left. So when you read "compound miter saw," you are looking at a single bevel miter saw. In these saws, you can make angled miter cuts in both directions, but bevel cuts only in one direction. This is because the design allows the saw blade to tilt only in one direction, usually to the left. The following are some of the more popular brands on the market at the moment:
The versatility of two bevels should cover the needs of any new woodworker. The design of the saw head is rather different from a single beveled saw and can tilt in both directions. A dual beveled miter saw can perform both miter and bevel cuts in both directions on the workpiece. With this type of saw, you can perform multiple cuts faster than on a single bevel saw. The following are some of the more popular dual beveled brands on the market:
Both single and dual beveled miter saws have their uses, advantages, and disadvantages. The following basic considerations largely determine their suitability for a particular task:
This factor is determined by the type and complexity of projects you are undertaking. If you are a pro, time is money, and the faster you can get things done, the more you can earn. Even as a DIY enthusiast, speed will be a factor if you have a busy schedule and need to get things done in a short period.
In terms of making a project easier and accomplishing cuts faster, a dual beveled saw has a decisive advantage over a basic compound miter saw. In a single beveled saw, if you want to make matching compound cuts on a piece of crown molding, after making the first cuts, you will have to take the piece and flip it to get the desired results. This can be time-consuming, especially if you have a lot of long pieces to work with.
In a dual beveled compound miter saw, you no longer have to flip the workpiece to get matching compound cuts. Instead, all you have to do is tilt the saw into the opposite direction, adjust the position of the workpiece, and then perform the cut. This can be accomplished much faster on a dual beveled saw and is more convenient when handling longer pieces of crown molding.
This is somewhat related to the speed factor. In a single beveled miter saw, every time you flip the workpiece, you have to deal with the placement and positioning of the workpiece from scratch. While working on repetitive cuts, the chances of mistakes and inaccuracies creeping in are higher. Again, dual beveled saws are superior here, since you don't have to make as many adjustments as you have to on single beveled saws.
Accuracy is more of a concern for professionals, especially those who work on premium quality woods, and on high-end woodworking projects. If you belong to this class of users, a dual beveled compound miter saw is the more appropriate choice.
This is more of a concern for the amateur and DIY enthusiast woodworker, rather than professionals. Single beveled saws are the cheapest and most accessible type of compound miter saws available in the market right now. Some smaller and lower powered models can be had for less than $100 brand new. Dual beveled compound miter saws will typically retail for above $200-$250 and are oriented towards professionals and experienced amateurs.
When compared to other stationary saws like table saws, miter saws are more compact and have a moving saw head working on a stationary workpiece. The wider the range of movements of the saw head, the wider the variety of cuts you can perform with that particular miter saw. These saws are best suited when you have to perform the same type of cuts repetitively on similar workpieces. Crown molding, frames, and trims are some of the most common projects which can benefit from a miter saw.
Compound miter saws have largely replaced standard miter saws in the marketplace, so the choice these days is largely between single beveled and double beveled version. You have to balance your priorities based on the criteria mentioned above, of speed/accuracy and budget, to figure out the best choice for you.
Single beveled saws are ideal if you do not have a lot of tasks to handle, which is often the case for minor home improvement and amateur wood-working projects. They can perform all the cuts that a dual beveled saw delivers. You will just have to put in more time repositioning the workpieces. If that is not a major issue for you, pick a single beveled miter saw. They are also the recommended option if you have budget constraints.

When deciding on a Single Bevel vs Double Bevel Miter Saw there are key factors that need to be taken into consideration. Choosing a particular model of compound miter saw can be tough, here are the key features:
Amps: The number that denotes the power of the motor used in the saw. Choose higher amps if you want more cutting power
Blade Size: Mentioned in inches, the larger sized blades can make longer cuts. Most common sizes range between 8, 10, and 12 inches.
Positive Stops: Preset points that allow you to make cuts on specific angles. The larger the number of stops on a saw, the lesser time you need to make adjustments.
Depth Stops: Adjusts how deep the cuts from the blade will be, by adjusting the height of the blade.
Table Extensions: These are accessories that connect to the sides of the saw, useful when you are dealing with longer stock pieces.
Laser Guides: They are useful in improving the accuracy of the saw, as they project onto the workpiece and show you exactly where the blade will cut.
