DeWalt DWS780 vs Bosch GCM12SD: which miter saw is right for you …?

The basics

DeWalt DSW780 vs. Bosch GCM12SD

DeWalt DWS780 Miter Saw

The Bosch is slightly larger than the Dewalt, around 4 inches, and is also a bit heavier. Although it is larger, it has a smaller footprint thanks to Bosch’s patented “Axial-Glide” system. Instead of a traditional miter saw installed where the blade moves on sliders, the Bosch has articulated cast aluminum arms that can feel a little whimsical until you feel how much this thing slides in. candy. So smooth, in fact, Bosch knows not everyone will like it, so they included a wrench just to increase the tension in the joints. Articulated joints are sealed bearing units, allowing smooth movement every time, no more cleaning sawdust from rails or fighting with a sticky machine. This design means that no clearance is required at the rear of the machine. It can sit almost against a wall, which is a great space saver, whether in your workshop or on a construction site.

The Bosch’s weight can be a drawback for some people at 65 pounds, however, it only weighs 9 pounds more than the Dewalt. The Dewalt is based on the most standard gliders, which means you will need to plan for an addition of 10 to 12 inches at the rear.

Cutting capacity

The Dewalt and Bosch both have 15 amp motors with a top speed of 3,800 rpm no load. The differences between the two boil down to the cutting ability.

These two saws improve the clearance of many previous 12-inch miter saws. Both have a decent capacity, however, with a vertical capacity of 6 ¾ “of base molding and up to 7 ½” of interlocking crown molding, Dewalt’s capacity exceeds that of Bosch by 6 ½ “on the left side. only (5 ½ “for the right side). The Dewalt also has a larger horizontal capacity of 16 “to 14” from Bosch.

The Dewalt DSW780 features adjustable stainless steel miter stop plates, with 10 positive stops. It also includes a manual control so you can adjust it to any angle. The Bosch, meanwhile, has an easy-to-read steel miter scale, but the notches themselves are plastic. Some users are concerned that this will cause the accuracy to decrease over time. It has six preset miter notches and five current bevel notches, but again, it has an adjustable manual override. The Dewalt has 60 ° right and 50 ° left miter capacity, while the Bosch has 60 ° right and 52 ° left capacity, 48 ° bevel angle on both sides. Dewalt does not list the maximum bevel angle, but there is a 45 ° overhang capability that allows you to cut slightly beyond 45 °.

As with many newer Bosch saws, an effort has been made to consider ease of use. The miter and bevel settings are on the front of the saw, which is nice and one wonders why other brands haven’t put more effort into making sure the controls are in a comfortable position to use. In comparison, the bevel adjustment on the Dewalt DWS780 is on the back of the saw, which can be difficult to access.

The GCM12SD features Bosch’s pre-aligned Squarelock quick release fence system that Bosch promises you never have to adjust and will ensure perfect material alignment every time. Keep in mind that they are likely to fill with sawdust, so be prepared to clean and lubricate this system on a regular basis.

Bosch and Dewalt both supply these calibrated saws, although some Bosch users have had issues with squaring and following the blade right out of the box. The Dewalt doesn’t appear to have these same issues, although some users are concerned about the lateral movement of the blade.

Many users are disappointed that the Bosch, with its high price tag, does not include a laser. Dewalt also doesn’t include a laser on the DWS780 – but they do better. The DWS780 includes what Dewalt calls its “XPS Cross Cut Positioning System”. They are simply two lights that shine on your material and cast a shadow from the blade exactly where the blade will fall. It is not necessary to calibrate or compensate for a fixed line thickness. The shadow will indicate the exact cut each time and help brighten your work area at the same time.

Both saws have see-through blade guards and users report that the blades in both are quick and easy to change.

Dust collection

Both Dewalt and Bosch miter saws have a dust collection system and each includes a dust bag. Dewalt claims its dust collection system recovers 75% of the dust it generates, although some users have complained that while the dust collector itself is useful, the included dust bag is so small it’s hardly worth the effort. to be used.

Bosch, on the other hand, claims that its dust collection system with vacuum collects 90% of the sawdust generated. Many users have been impressed with the dust collection on the Bosch, although a small number complain that Bosch has exaggerated by claiming a 90% dust collection.

More efficient dust collection is not only helpful for our health and convenience when using the tool, but less dust helps to increase tool life. It should be noted that as long as the bearing units on the Bosch arms maintain their tightness, dust should not be an issue with this design. As for the standard rail system, it will be beneficial to ensure that the rails are kept clean and lubricated to prevent sticking during the life of the saw.

What’s in the box

Both saws include a 12 inch 60 tooth blade, dust bag and material clamp.

The Dewalt is delivered fully assembled. The Bosch saw requires a ready-to-use assembly. However, it’s as easy as installing the button and lever on the front. It is very well packaged with additional backing cardboard to keep the unit stationary during shipping. Both machines are calibrated, have a carrying handle on the top and handles on each side for easy use.


Dewalt is a company well known for the generous manufacturer’s warranty. For the DWS780, Dewalt offers a three-year limited repair warranty against defects due to defects in materials or workmanship. This warranty applies only to the tool itself, not to the accessories. Dewalt also offers a one-year free service contract where they maintain the tool and replace worn parts with normal use, as well as a 90-day no questions asked money back guarantee. Some users have reported that it takes persistence for Dewalt to repair or replace products under warranty.

Bosch offers a relatively standard one-year repair or replacement warranty and a one-year free service contract. As mentioned above, some users have complained about squaring and tracking issues right out of the box, possibly due to shipping. Most of these users reported that Bosch replaced their faulty saws under warranty.

Summary and recommendation

If I chose between the Dewalt DWS780 and the Bosch GCM12SD, I would probably go with Dewalt. The Dewalt comes with the ‘XPS Cross Cut Positioning System’, which helps you see exactly where your blade is going to fall. The trigger plates are stainless steel compared to the Bosch plastic trigger plates. The Dewalt also comes with a more generous warranty.

I wish the Dewalt had more dust bag capacity as this is one area where the Bosch wins. Even still, I think the Dewalt DWS780 is the best choice here.
