5 Best 12 Inch Miter Saws Reviews

Dewalt DWS780, Best 12 inch Dual Bevel Sliding Compound Miter Saw

Our first product is the Dewalt DWS780, and in our opinion it is the best 12 inch miter saw out there, along with being the best 12 inch compound miter saw! First off, what assures of the quality and durability of this product is that it is a Dewalt product. They’ve acquired a name for making some quality woodworking tools, and the Dewalt DWS780 definitely lives up to the brand value!

Apart from the just the face value of the Dewalt DWS780, the entirety of the miter saw is made up of a stainless steel base, and the build of the entire miter saw is designed to be durable throughout tons of tough work. With the positive detent plate installed in the miter saw, you have positive stops for your blade at angles of 0, 22.5, 33.9, 45 and 49 degrees. Yes, the bevel angle goes from 0-49 degree angles. On top of that, the miter gauge will allow you to swing 60 degrees to the left and 50 degrees to the right. So, you’ll never lack versatility when it comes to the best 12 inch saw! 

You can also rest assured that the Dewalt DWS780 will be extremely capable of handling crown molding, with a great tall fence, that will accommodate large pieces of wood easily. One of the few things that this miter saw falters on, is the fact that its dust collection system sometimes clogs up too fast. However, you won’t be worried about it too much; whereas the high powered 15 amp motor will run through your pieces fast and accurately!

  • High powered saw with precise cuts
  • Very durable
  • Motor remains cool with dual copper windings
  • Easy to use
  • Dust collection system falters occasionally

Bosch GCM12SD, 12 inch Dual Bevel Sliding Glide Compound Miter Saw

Our second product today is the Bosch GCM12SD miter saw, and it’s another one with great brand value behind it! What separates this from the rest of the competition is the unique patented sliding glide mechanism that Bosch have implemented on it. What does it do? Well, when you’re using this miter saw, you’ll feel like this is the smoothest miter saw you’ll ever use. And for some, it still lives up that reputation. The ease at which you can guide the blade on this miter saw is on another level.

The Bosch GCM12SD also comes with the exclusive axial glide mechanism, that allows for it to make compact cuts with ease. Not to mention, you’ll maintain the utmost accuracy and precision when making your cuts. Since it’s also a dual-bevel miter saw like the Dewalt DWS780, you’ll have the versatility to make various types of cuts. The miter gauge detents are stainless steel as well, making you comfortable about how durable this saw will be. 

You’ll also be able to make easy adjustments with the square lock fences, on both sides of the rails. However, seeing as the Bosch GCM12SD doesn’t falter, you could be wondering why it falls behind the Dewalt miter saw. Well, it is just a matter of comfortability with us and how seamlessly the Dewalt DWS780 cut through wood pieces. The Bosch GCM12SD is still a perfectly good choice as well.

  • Patented Sliding Glide system
  • Exclusive Axial Glide system
  • Can accommodate for larger crown molding
  • Has a soft-grip ambidextrous handle for comfort
  • Quite heavy

Makita LS1219L, Best Portable 12 inch Dual Bevel Compound Miter Saw with Laser

Our next product is a Makita miter saw, and it is the Makita LS1219L. What’s best about this miter saw is that this is another lightweight miter saw for you, and this one is our top pick for the best 12” miter saw for portability! It also has a 15 amp motor with 3200 RPM that allows it to easily make cuts through your material.

With its dual bevel ability, you can shift the blade on the Makita LS1219L miter saw within the range of 0 to 48 degree angles either side, for bevel cuts.

Extremely versatile right? 

Among its features, it also has an electric brake added to ensure you are able to quickly stop your blade from moving, if needed. The Makita LS1219L miter saw also has a dust collection system, but you only get the dust bag upon purchase. The dust vacuum is sold separately. A couple of things that could make you shy away from this miter saw, is that it is quite hefty in price, and the manual isn’t really clear on how to use this miter saw (even if you’re well acquainted with miter saws).

  • Includes a good laser for better and cleaner cuts
  • 15 amp motor makes it a strong miter saw
  • Best portable miter saw
  • Durable
  • Hefty price
  • Confusing instruction manual

Makita LS1221, 12 inch Compound Miter Saw

Our fourth product we have on for show is the Makita LS1221 compound miter saw. One thing that lets it down compared to the other saws, is the fact that this is a single bevel saw. However, despite only being able to use it on the left side of the blade, you can make 9 positive bevel stops! This miter saw also has a great advantage of being a very durable miter saw with the least amount of plastic bits in it. 

You can easily accommodate the Makita LS1221 miter saw to make great crown molding cuts as well. This miter saw is also fitted to be more powerful than most other miter saws, with 5000 RPM with a 15 amp motor. This will allow you to cut through your materials faster than most other saws.

Dewalt DW715, 12 Inch SIngle Bevel Compound Miter Saw

Our last product we have on the list is another Dewalt miter saw! The Dewalt DW715 is falls behind the rest with a few features that aren’t on par with the rest of the miter saws. One being the fact that it is a single bevel miter saw, hence you lack the versatility of being able to tilt your blade both sides. Another one is that it is considerably noisy when in use, and can be a bit inconvenient. 

However, the Dewalt DW715 miter saw does have its merits. It does have a detent plate for miter cuts, and is impeccably accurate when it comes to making cuts. You’ll find changing angles while making numerous cuts to be very easy. This is helped by the stainless steel detent plate providing you with 11 positive stops. Even though the miter saw is single bevel, you can tilt your blade from 0 to 48 degree angles to the left. On top of that, there are positive stops on your bevel gauge at 0, 33.9 and 45 degree angles, to assist you with crown molding!

While this miter saw may be at the bottom of this list due to some features, the Dewalt DW715 has a very powerful 15 amp motor with 4000 RPM, which is able to cut through its materials with ease! So despite the drawbacks, you can definitely find this to be a very handy tool!

  • Powerful motor
  • Durable miter saw
  • Is a sliding compound miter saw
  • Single bevel saw
  • Noisy

A Buyer’s Guide for Miter Saws

Now that you know our choices in the 5 best 12 inch miter saws for you, it’s time to know what features and traits these miter saws have, that you should look out for! While there is an ideal setting to every factor, it is key for you to remember that there will be trade offs between each perk when you’re trying to select one of yourself.


Durability is something you always have to keep in mind, especially if you want the best out of your miter saw. Or any tool for that matter. The factor of durability becomes more prominent based on how often you’re going to be using it. 

If you’re a professional woodworker, this is something you can not skim out on. You’ll always have to look for the top pick in terms of durability as well as functionality. However, if you’re just a hobbyist who occasionally does some small work, you don’t really have to be fussed about the best in terms of durability.

It is always wise to pick the best one out regardless.


We’ll move onto functionality next, as it goes hand in hand with durability. One of the biggest trade offs that you’ll have to make. Some miter saws might provide better functionality based on the features and perks they have. However, this causes them to lack in terms of durability.

Now, it isn’t the case all the time, but most times you’ll be in a dilemma of choosing between the longest running miter saw versus the most efficient miter saw. However, be sure to make a proper choice, as functionality determines the ease of use of a miter saw, along with how optimized it is.

Cutting Capacity

Considering you’re already on the hunt for 12 miter saws, you’re expecting to be cutting things that most other miter saws can’t handle. In that case, you’ll also need to focus on the cutting capacity of your miter saw.

The cutting capacity will not only make it easier for you to work because of the miter saw’s capability, but you’ll also gain tons of flexibility in the cuts you make. You’ll also have a much easier time in making crown molding cuts, if your miter saw has a high cutting capacity.


Since we’re speaking of versatility and flexibility, we need to look at the bevel of a miter saw. As you’ve seen from our list (and your experience probably), you can get single bevel miter saws, and double bevel miter saws. What’s the difference?

Well, a single bevel only allows your miter saw’s blade to be tilted to one side, whereas a double bevel allows the blade to tilt to both sides. You can also find sliding compound miter saws, that allow for you to move the blade’s position forward, allowing you to cut bigger pieces of material. 

A sliding miter saw is definitely the best among the three, but that’s where the price comes in. Let’s not get off topic though. If you want the best flexibility and versatility in your woodwork, then you should definitely look towards getting a sliding miter saw. However, if you’re not that keen on it, double bevel miter saws should work just fine for your bevel cuts and there are a lot of these saws on the market. 

A single bevel also works fine, but it limits you from doing more complex jobs in the future without having to spend on another miter saw.


This is the most obvious one that comes with any power tool you’re looking for. Your top pick for a miter saw should definitely make accurate cuts. From bevel cuts to miter cuts, you’ll need to know the blade on your miter saw is good, along with the other features it has built in it (such as a laser). 

This is a factor which you cannot make any trade offs in if you want smooth and clean cuts on your materials. However, if you’re dealing with lumber or materials which don’t require clean cuts, then you don’t have much to worry about.

Fences and Gauges

Accuracy of your miter saw can also depend on the fences and gauges of your saw. The fences are in-built parallel devices that help keep your materials straight, to help make true cuts. 

Gauges on the other hand help to make precise angles for you to help get the perfect cut (for example: miter gauge). It’s best to ensure your choice for miter saw has the best of both!

Motor and RPM

The motor on a miter saw helps determine how much power the entire tool has. For a power tool such as a 12 inch saw, you’ll want to make sure you have high powered motors, such as 15-amp motors. Most of the miter saws you’ll see nowadays have 13-amp motors at least, but 15-amp motors provide the best work. 

RPM also helps determine how well your saw will work. How easily a 12 inch miter saw will be able cut through thicker and harder materials, depends on the RPM. The higher the better.

Using A Miter Saw

If you’re going to just acquire one of these tools, then it is best if you learn about them, and how you go about using a miter saw!

The Takeaway

Now that we have gone through the whole list, we can reiterate that the best 12 inch miter saw is the Dewalt DWS780 in our opinion. This miter saw gives you the whole package in terms of a great motor that can cut easily through your materials. Not to mention, you’ll get very accurate cuts all the way through, without any rough edges left. The Dewalt DWS780 did get rivalled by the Bosch GCM12SD, and just edged it out. When it comes to these power tools, we’ve gone through a lot of testing and research to ensure you get the best tool to help you out based on features and performance!
