The Cutting Capabilities

Bosch GCM12SD

The Bosch GCM12SD comes with a new axial glide system that enables you to make smooth and large cuts in a tight space. Its cuts are very precise and smooth, and no rails obstruct your work like on the sliding varieties.

You don’t have to worry about the rail wearing which can lead to some inaccuracy in the cuts.

Its 1800 watt, 15 AMP motor is a powerful asset that allows it to work all day long, whether at a building site or in a workshop.

It enables you to make tough cuts without worrying about the durability of the tool

The Bosch GCM12SD is capable of cutting a huge 4.3 by 12-inch cut –quite an impressive number.

Combine the cutting capacity with the strength of the motor and you get a machine that is ready to take on any piece of timber.

Its miter angle ranges from 0 to 52 degrees to the left and from 0 to 60 degrees to the right.

Moreover, its double bevel angle reaches 47 degrees.

It truly provides you with a lot of versatility to cut any sort of tight angle.

The fast push button angle setting helps you make quick cuts at different angles.

Finally, the blade changes are pretty quick thanks to the spindle lock that keeps the saw working quickly.

Dewalt DWS780

The Dewalt DWS780 is also strong and is able to cut through tough materials easily.

Running on a 1675 watt, 15 AMP motor, it enables you to adjust its speed to suit a variety of materials.

This opens doors for you to work on other materials than wood such as steel, plastic, and much more. By adjusting the speed, you’ll get the perfect finish for any workpiece.

It can cut 4.3 inches deep and 12 inches wide, which means its cuts are large enough to take on tough pieces of lumber.

The bronze rail guides provide you with extra smoothness and precision.

Its single bevel angle ranges up to 49 degrees on both the left and right bevel settings.

You can also reach multiple angles quickly with the quick release of bevel controls.

Furthermore, its miter angle ranges from 0 to 60 degrees on the left and to 50 degrees on the right.

The miter cam lock also makes it easy to set and change the angles quickly, and with the existing bevel angles, you’ll be able to make some tight and accurate cuts on large workpieces.

The Dewalt DWS780 makes use of an XPS shadow line cut indicator that guides you with precision through your cut and lights up both the blade and the material while you’re cutting, that’s why it wins the battle of cutting capabilities.

Winner: The Dewalt DWS780.

The Safety

Bosch GCM12SD

Bosch doesn’t underestimate the importance of safety with these kinds of power tools. That’s why the blade is covered and kept away from the user as it spins.

You can lock the handle into 4 different positions that suit both left-handed and right-handed users and make the saw easy and comfortable to use.

In addition, its controls are very easily accessible and simple to use without any need to move around. This makes jobs during which you need to constantly alter the saw easier.

Dewalt DWS780

You don’t have to worry about any safety hazard with the Dewalt DWS780.

Its blade is well covered with a strong, large, and automatic cover. It’s also never exposed except when the saw is in the process of cutting through material.

Moreover, it also has a powerful base that makes it sturdy and keeps a rock-solid position on a flat surface. This is especially helpful if you’re dealing with larger and heavier timbers.

Bosch GCM12SD

The Bosch GCM12SD is quite a heavy-weight champion. At 88 pounds, it’s not the easiest miter saw to move and carry around, so you shouldn’t opt for it unless you’re going to work from the same location or do little to no relocation.

Dewalt DWS780

At 56 pounds, you can easily take the Dewalt DWS780 with you wherever you’re planning to work.

Indeed, you can find lighter saws on the market, but none of them will have features that can compete with those of the Dewalt DWS780’s.

It’s pretty satisfactory for general purpose use.

The Dewalt DWS780

Yes, it does. Dewalt has your back with any manufacturer defects for 3 years, a year of service, and you can get your money back during the first 90 days if you’re not satisfied with the product.

It’s one of the safest compound miter saws you’ll find on the market. The brightly-colored blade is guarded with a cover that always keeps it away from you.

  • Can I use my Dewalt DWS780 with a 100V / 50 Hz power supply?

Its recommended power supply is 120 V / 60 Hz. If you use another power supply, the functionality of the saw will most probably be compromised.

Your Final Decision

As you can see, the Dewalt DWS780 beats the Bosch GCM12SD at most points of comparison.

It has more versatility and flexibility, it’s lighter even though it’s more durable as it’s made of stainless steel and not aluminum (which, ironically, is supposed to have the advantage of being light), and it comes with an XPS light system and a more reassuring warranty. That’s why we picked the DWS780 as the best miter saw for crown molding.

However and unsurprisingly, it comes at a relatively higher price. So the Bosch GCM12SD is a lot more affordable, has better dust collection, and a very compact design.
