Types of DeWalt Miter Saws
The idea behind the first miter saws was pretty straightforward. Take a handheld circular saw and mount it on an arm, thus providing more stability and better repeatable accuracy. Although the powered circular saw was invented around 1930, the first miter saw didn’t appear until the 1960s. There have been a number of developments since, and miter saws come in several formats.
Basic Miter Saw
Miter saws are often confused with chop saws. While a chop saw only cuts up and down (hence “chop”), even the most basic miter saw does this motion but can also rotate left and right. As a result, miter saws are capable of cutting angles up to 45 degrees, and many will cut slightly greater. Fixed stops (called detents) are often provided at common angles like 15 or 30 degrees to make setting up the saw quicker.
Depending on its size, a basic miter saw can be useful for a variety of framing jobs or cutting trim and moldings. However, the development of the compound miter saw—and the added versatility it offers (see below)—means that basic miter saws are now a rarity.
Compound Miter Saw
In addition to being able to rotate horizontally, the head on a compound miter saw can tilt through the vertical axis. The blade then slices in from the side, creating a beveled cut. A basic miter saw can do exactly the same by rotating the table, but the compound miter saw can both rotate and tilt, thus giving it the ability to cut a variety of compound angles, from which it gets its name.
There are two types of compound miter saws: those that can tilt to one side, which are known as single bevel, and those that can tilt either way, which are known as double bevel. A DeWalt single-bevel compound miter saw can actually create the same angles as a DeWalt double-bevel miter saw, but the workpiece would need to be reversed, which is not always convenient. However, the double-bevel option usually increases the price.
Sliding Compound Miter Saw
Although the compound miter saw is more versatile than the basic model, it still has one major drawback: the blade can only rise and fall. The size of lumber it can cut very much depends on blade diameter.
The sliding compound miter saw dramatically increases cutting capacity by having the saw head mounted on horizontal rails. It can then be pulled toward the user as it cuts. This mimics the action of the radial arm saw invented by Raymond DeWalt in 1922. This combined action means that wide planks and flooring can be cut, making the DeWalt sliding compound miter saw an extremely flexible and productive tool for both the DIYer and trade user.
What to Consider When Choosing the Best DeWalt Miter Saw
All DeWalt miter saws are either single-bevel compound, double-bevel compound, or sliding compound models. Each is renowned for its accuracy and durability and has an extensive set of features. However, there are key differences that can have a major impact on choice. The following section looks at these in detail.
Size and Intended Use
Like all types of circular saw, DeWalt miter saws are defined by their blade diameter. The 12-inch models are the largest and the 7¼-inch models are the smallest. However, it is important to check actual capacities for each model rather than assume, for example, that two 12-inch DeWalt miter saws have the same cutting capacities. They may not.
Each DeWalt miter saw is capable of high accuracy, with easy-to-read scales and detents for fast setting of common angles. Fine adjustment is available when setting up the saw, which ensures precise angles are cut. However, the accuracy of the angles should be checked periodically.
Although DeWalt miter saws are often used as bench saws in workshops, their portability can be a major benefit. Buyers should check each model’s weight, as they do vary considerably.
Power
All of DeWalt’s corded miter saws have a 15-amp motor, which is the maximum supply provided by ordinary household outlets. It is also the standard for generators, if portable power is being used on a jobsite, for example.
The other option is to go cordless, and there are several DeWalt cordless miter saws available. A lightweight 7¼-inch model runs off 20-volt batteries, whereas high-performance 12-inch models use DeWalt’s unique Flexvolt batteries. For Flexvolt, two 60-volt units are used, providing an impressive 120 volts of power.
Those who want to buy spare batteries may want to consider the amp hours (Ah) rating. Higher Ah equates to longer runtime. DeWalt’s 20-volt MAX batteries, for example, are rated anywhere from 1.5 Ah to 12 Ah. While the latter cost considerably more, they can give as much as eight times the use between charges.
Accuracy and Ease of Use
DeWalt tools have long been a preferred choice of contractors and tradespeople because of their durability and accuracy. Beyond the detents that allow quick and easy setup of angled cuts, another helpful feature is the tall fence. It’s a feature on several models and provides good support, particularly for larger workpieces. These fences run on slides, so it is easy to move them out of the way when they are not needed.
Laser guides are fitted on many miter saws, but setup can be difficult and regular adjustment is required. Several DeWalt miter saws use an upgraded system called XPS. This shines LED light down either side of the blade, thus creating a shadow line on the workpiece. Unlike lasers, this not only shows where the blade will cut but also the blade thickness and allows more accurate cutting.
DeWalt sliding compound miter saws also have a quick-set depth stop, so grooves or trenches can be cut in wider stock. Plus, a wide variety of miter saw stands are available, both from DeWalt and other makers.
Safety Features
Miter saws, like many power tools, use a system that prevents accidental starts. Called a lockout trigger, it involves a button that has to be pressed at the same time as the trigger is pulled in order to start the tool. It’s effective and doesn’t hinder operation, and it makes starting the saw accidentally very unlikely.
All DeWalt miter saws have a guard that wraps around the blade and moves out of the way as the cut is made. Clamps can help secure the workpiece so the user’s hands don’t need to be anywhere near the blade.
While DeWalt miter saws have an electronic brake so they come to a stop swiftly and safely, waiting for the blade to slow down after a cut can be frustrating. However, rubbing a hand or other item against the side of the blade to reduce speed is dangerous. Never put your hand on a moving saw blade.
Our Top Picks
It’s now time to look at our top picks for the best DeWalt miter saws in several categories. As DeWalt’s own descriptions can often be very similar, we have also included the part number of each tool for clarification.
Best Overall
DeWalt 12u0022 Double Bevel Sliding Compound Miter Saw
DeWalt’s range-topping 12-inch double-bevel sliding compound miter saw is an outstanding tool. The headline statistics are the class-leading cutting capacities, but this is just one of many areas where it excels.
The DWS780 model can cut bevels in 7½-inch crown moldings and 6¾-inch base moldings. It can saw through 4×4 posts and crosscut 2×14 dimensional lumber (maximum crosscutting is actually 13⅞ inches). Tall sliding fences, clamps, and extending supports on either side make it easy to mount almost any material for cutting. It is quick and easy to set up, with chunky knobs, levers, and positively locating detents. The XPS cutline system shows precisely where the blade will cut.
There is a reassuring solidity about the saw, although its 66 pounds is a bit heavy. The dust collection is very good and claims 75 percent efficiency. The bag is a little small, but that’s true of all miter saws.
The DeWalt DWS780 costs more than many DIY users will want to pay, but for many professionals it is one of the best miter saws available.

Runner-Up
DeWalt Sliding Compound Miter Saw, 12-Inch
The DWS779 is a DeWalt double-bevel miter saw. At first glance, this DeWalt sliding compound miter saw (DWS779) and the brand’s double-bevel sliding compound miter saw (DWS780) are quite similar. Both are 12-inch double-bevel sliding compound miter saws, and they share the same powerful 15-amp motor and the same impressive 3,800-rpm speed. So where are the differences?
Cutting capacities are the same, except for the maximum height which is a little less at 6¾ inches. The slide mechanism differs, and while it runs perfectly true, it does add weight. Other component changes take the total up to 56 pounds. Neither laser nor XPS cutline system are included, though the latter can be added at extra cost.
Whether these differences are important depends on intended use. For a tradesperson needing to carry the saw around regularly, the extra weight could be a factor. However, the notably lower price of the DWS779 makes it much more accessible to DIY enthusiasts.

Best Bang for the Buck
DeWalt 12-Inch Miter Saw, 15-Amp, Single Bevel
This DW715 model is another DeWalt miter saw based on the brand’s powerful and reliable 15-amp motor. This model offers single-bevel compound cutting, and while it doesn’t have the crosscutting ability of the sliding models, its ability to saw through 2×8 dimensional lumber and boards up to 7¼ inches wide is still impressive.
With only single beveling, the fences are simpler on the DW715 but still slide on the left and offer good depth for workpiece support. A robust clamp is included, though there are no side extensions. Setting is as quick and positive as expected from DeWalt miter saws, with 14 detents for common angles. Neither laser guide or XPS are available for the DeWalt single-bevel compound miter saw.
DeWalt doesn’t make cheap miter saws, but the DW715 is competitively priced for a 12-inch miter saw of this quality and all-around cutting ability.
Product Specs
- Type: 12-inch single-bevel compound
- Cutting capacities: 5½ inches vertically, 2×8 dimensional lumber
- Weight: 42.8 pounds

Best for DIY
DeWalt 15 Amp 10-in Compound Miter Saw
A 10-inch miter saw is arguably the most popular size both for DIY enthusiasts and contractors who don’t need massive capacities and are looking for a portable tool. The DeWalt 10-inch single-bevel compound miter saw is once again based around the powerful 15-amp motor, and this model runs at up to 5,000 rpm.
While absolute cutting dimensions are clearly less than a 12-inch sliding model, the 10-inch DeWalt has no trouble with 2×6 dimensional lumber. Perhaps, more importantly, it can accommodate 2×4, a common material for DIY and craft projects, at both 90 and 45 degrees.
As expected from DeWalt, this DWS713 model is well made with smooth operation, easy setup, and repeatable precision with 14 detents. However, it does not include a cutline system. Pricing is similar to the 12-inch model, so choice will probably come down to cutting capacities versus portability.
Product Specs
- Type: 10-inch single-bevel compound
- Cutting capacities: 4¼ inches vertically, 2×6 dimensional lumber
- Weight: 31 pounds
- Part number: DWS713
Pros
- Tremendous power
- Very portable
- Competitive price
Cons
- No laser or XPS
- Small dust bag

Best Cordless
DeWalt FLEXVOLT 120-Volt MAX 12 in. Miter Saw
Where most cordless rivals limit themselves to 10-inch models, DeWalt’s class-leading double-bevel sliding compound miter saw is a full-size 12-inch tool. In essence, it’s like the brand’s corded 12-inch double-bevel sliding compound miter saw with the benefit of battery power. In fact, it also comes with an AC adapter, so it can be powered by plug if preferred.
In order to provide sufficient performance, DeWalt uses two 60-volt, 6-Ah batteries. Not only are these among the most powerful batteries offered by any tool manufacturer, but they also incorporate unique technology that means they can sense the power demanded of them. Take one off the DeWalt miter saw and attach it to a DeWalt 20-volt Max hammer drill, for example, and the battery will automatically switch to 20-volt supply.
The DeWalt cordless 12-inch miter saw is a remarkable achievement, and there will certainly be professionals for whom it will be worth the investment. However, many may find it difficult to justify the price.

FAQs
The information above offers a comprehensive overview of how the various DeWalt miter saws function and focuses on more detailed specifications for the best DeWalt miter saws currently available. During our research we came across a number of questions that crop up quite often, so we have answered those below.
Q. What is the main use of a miter saw?
A miter saw can be used for crosscutting trim, moldings, planks, and dimensional lumber. It can also cut angles. We have mentioned maximum cut sizes in the article above. However, miter saws cannot cut through large sheet materials. For that type of job, a circular saw or a table saw would work.
Q. How do I change the blade on a DeWalt miter saw?
Changing a DeWalt miter saw blade is quick and easy. A manual is provided with the tool, as is a wrench. There may be minor differences among models, so check the specific tool’s instructions. Also, be careful with the old blade, which can still be sharp enough to cut you.
- Make sure the miter saw is disconnected.
- Move the blade guard out of the way.
- Push down the spindle lock.
- Undo the bolt that holds the blade.
- Fit the new blade, and reverse the process.
Q. How do I adjust my DeWalt miter saw?
Depending on the type of DeWalt miter saw, there may be adjustments for rotation, beveling, and depth of cut. Each uses simple levers or easy-to-use buttons. The owner’s manual provides details specific to each model.
Q. What is the DeWalt shadow line?
DeWalt’s shadow line system is called XPS. Two LEDs shine on either side of the blade, creating a shadow on the workpiece exactly where the blade will cut. It is more precise than laser guides because it shows the actual width of the blade. It is also easier to see than a laser, particularly in sunlight.
Q. Does DeWalt make a dual-bevel cordless miter saw?
Yes. The DeWalt compound sliding miter saw is a dual-bevel model called the Flexvolt 12-inch miter saw.
