It does come with an inefficient dust collection system, and it lacks laser and LED lights.

Pros & Cons

  • Lightweight
  • 13 positive bevel stops
  • No laser or LEDs
  • Inefficient dust collection system

Final Verdict

The DWS709 is another Dewalt product that we love. It has a powerful motor; it is lightweight, and it has decent cutting capacities that will most likely get the task done. However, its dust collection system is inefficient, and it doesn’t come with laser or LEDs.

5. Milwaukee 6955-20 – High Accuracy

Milwaukee 6955-20

The Milwaukee 6955-20 saw is known for its exceptional accuracy that goes up to 0.1 degrees, and self-zeroing system for all miter angles.

Besides its accuracy, 6955-20 has another distinctive feature that you probably haven’t seen before. It starts slowly at first to allow you to go into the material gently the first couple of seconds then speeds up to its 3200 RPM.

The 6955-20 has a dual bevel with 9 positive stops, and left and right bevel range of 0-48 degrees. It also provides a dust collection system of 75%.

Like the DWS780, the 6955-20 also has lights that cast a shadow where the blade will land. However, the 6955-20 is a little on the heavier side with a weight of 78lbs. The 6955-20 has 13-1/2” of crosscut capacity at 90 degrees. Also, it comes with a 60T blade for a smoother finish.

Pros & Cons

  • High accuracy that goes up to 0.1 degrees

Final Verdict

The Milwaukee 6955-20 is the best saw you could pick if you’re looking for precision and accuracy. It has guide lights, an accuracy of 0.1 degrees, and a self-zeroing system. It is not the most powerful motor with only 3200 RPM, and it is expensive and heavy.

How To Pick a Miter Saw

When it comes to picking a miter saw, there are a few things that you need to take into consideration


It goes without saying that you need to look for a saw within your budget. However, make sure not to pick the cheapest saw you find. You get what you pay for.

Accuracy and Precision

You wouldn’t want your saw to have low accuracy as that can ruin your task at hand. You should look for saws that have a laser or LED lights that show where the blade will land.

Some people prefer LEDs to laser as it casts a shadow where the blade will land exactly, rather than right next to the blade like the laser does. However, LEDs can be useless when working in daylight, as you wouldn’t be able to see that shadow clearly.

Cutting Capacities

There’s no right or wrong here. Cutting capacities depend on how big your material will be. In order to be safe, if you’re unsure, a 14” on crosscut capacity should do you just fine. You could also go up to 16” if you want to be ultra-safe. A safe vertical molding capacity would be around 6” and a vertical base crown molding capacity around 6” as well.

Dust Collection

Having dust go everywhere, including your face, can slow down your progress and is just annoying to deal with. Not all dust collection systems are efficient, so be careful when looking for a saw with a good dust collection. Note that you can always purchase a separate one.


The blade controls how fast you’re cutting and how smooth your finish is. A 60-T blade should do you just well if you’re looking for a somewhat smooth finish. However, it would be better just to purchase a separate blade that does precisely what you want rather than depend on the blade that comes with the saw.

12-Inch Vs. 10-Inch Miter Saws:

Price Point

When it comes to the price point, 10-inch saws are generally less expensive than 12-inch miter saws.

Accuracy and Precision

There is no clear winner at this point. 10” blades are usually more accurate and precise. However, you can attach a 10” blade to a 12” saw. There are other factors that have a significant advantage when it comes to precision like having laser, LED and any additional feature that a saw has over the other.


12-inch saws have a larger radius; therefore, a heavier weight. You can easily find lightweight 12-inch saws, but they aren’t as common as 10-inch saws. However, that may not really be an issue as 12-inch saws are faster and more efficient than their 10-inch counterparts.


Generally, 12-inch miter saws tend to have more powerful motors in order to withstand their heavier weight, and because 12-inch miter saws are designed for heavy-duty tasks.

Cutting Capacities

Because the 12-inch saws have more powerful motors, they have higher cutting capacities. You can cut thicker or wider materials with 12-inch saws that 10-inch saw would not be able to withstand.


10-inch saws usually have higher RPM than 12-inch saws, which leads to a smoother finish.

Final Words

12-inch miter saws are powerful. They cut deep and fast, which makes them ideal for more significant tasks. Picking a good 12-inch miter saw is not an easy task as you need to look into specs, capacities, weight, and price point. Here are our top 2 recommendations.

Starting with our first place winner, the DEWALT DWS780 is a customer’s favorite. It is lightweight, features an XPS system for accuracy, and provides decent cutting capacities. However, the XPS system can be entirely useless in daylight, as you will not be able to see the shadow.

Coming in second place is the Bosch GCM12SD, which is known for its compact size. It can save you lots of space and allow you to work in tighter areas. In addition, it has an efficient dust control system that can absorb up to 90% of the dust. However, it is not as accurate as you’d want it to be, as it doesn’t offer laser or LEDs, making it hard to use for beginners.
