Choosing between the Bosch GCM12SD vs DeWALT DWS780 may not be as straightforward as you imagine. They share a 12″ dimension among other features. It doesn’t help that their blade speed is also similar at 3800RPM. So, how does one choose between these two miter saws? We start by comparing the rest of the features. Once you know the features, you can consider how they fit into your needs. I would encourage you to put brand preferences aside before settling for one. Let us have a look at how they compare.

- A bit heavy
- Does not have a laser
Features of the Bosch gcm12sd
Bosch gcm12sd allows you to adjust the miter table from 52° left to 60° right. The controls make it quick to adjust, and Bosch placed detents at standard angles to ensure that your often-used stops are accurate. They set the miter detents at 0°, 15°, 22.5°, 31.6°, and 45°, to the left and right. There is an additional stop at 60° to the right.
You can cut base moldings standing upright against the back fence. The maximum height for a straight cut is 3-7/8 inches. You can cut angles from 0° to 47° left, to a width of 6-3/4-inch.
When you cut bevel angles with the Bosch GCM12SD, the limits are 47° left and 47° right. It has bevel stops at 0°, 33.9°, 45° and 47° left and right. The maximum size for a 38° spring crown molding angled against the fence is 5-1/4 inches. 5-1/2 inches when cutting from 0° to 47° left bevel. For a 45° spring crown molding angled, you can go up to 6 inches.
The saw has an automatic electric blade brake. It stops the blade within 5 seconds of releasing the trigger. The brake is not adjustable, hence it requires monitoring and having the saw serviced if it should stop working.
Power and speed
The DeWALT has a powerful 15 Amp motor, and the no-load speed of the blade is 3800 rpm. That allows the 60-tooth blade a feed speed of 95 feet per minute with a chip load of 0.005 inches. The arbor size is a standard 5/8 inch diameter or a 1 inch with a collar.
The Bosch 15 Amp motor delivers three horsepower maximum and no-load speeds of 3,800 RPM. It is powerful, and it cuts many types of wood smoothly.
The brake used to stop the motor is an electronic brake. It should last a lifetime (Quora.com).
The ergonomically designed trigger handle with a soft grip is different from the DeWALT, which has a handle to the right of the blade. The Bosch handle is a large form-fitting handle with two triggers and within easy reach of your left hand.

What could have been better?
- Bosch GCM12SD should not require a few adjustments before first-time use.
- A safety gear would have made it a better saw tool.
- It could have been a bit lighter for easy movement.
- Ruler markings would have made it convenient to use.
- Both are easy to use and move around.
- Both miter saws use the same size engine to drive the same size blade at the same speed.
- They fall within a similar price range.
Differences between Bosch GCM12SD and DeWALT DWS780
- Bosch’s GCM12SD allows the saw to fit in a smaller area of the workshop than Dewalt’s.
- Bosch also cuts a wider range of angles than Dewalt.

So, which one will you pick? I will just reiterate that if you have limited space, I recommend going with the Bosch GCM12SD. Bosch and DeWalt miter saws are great tools that will improve any workshop. The difference between them is slight, but that separates the two. DeWalt is more versatile. Bosch is smaller enough to work in smaller areas. By now, you should have your best pick.
