DeWalt DWS780 Review
The DeWalt DWS780 is a 15 Amp double bevel sliding compound miter saw with a 12 inch blade.
Capable of a maximum no-load speed of 3800 RPM. It has a cutting capacity of 2x16 inch at 90 degrees and at 45 degrees it can cut up to 2x12 inch.
On the miter front it can cut up to 50 degrees on the left and a slightly higher range of 60 degrees on the right.
With regards to the bevel the DWS780 can work from 0 to 49 degrees in both directions. There are also positive bevel stops at 0, 22.5, 33.9, 45 and 49 degrees.
The DWS780 comes with DeWalt's XPS cross-cut alignment system. THE XPS shines a very bright LED along the face of the blade. This lights cast a very clean cut shade the is perfectly inline with the blade. This gives a small advantage over laser guides that may need to re-calibrated from time to time especially after blade changes.
There is also a version of the DWS780 available without the XPS system called the DWS779. The DWS779 is a cheaper alternative to the DWS780 to the tune of almost 200 bucks depending on where you purchase it from. You can read our comparison of both DeWalt miter saws here DWS779 vs DWS780.

Bosch GCM12SD vs DeWalt DWS780
So who is the winner in the Bosch vs DeWalt miter saw head to head?
The DeWalt machine is by far the most popular you will find on a busy work site. It has a proven reputation of being a real workhorse and the XPS system along with very precise miter and bevel adjustments means that is the more accurate of the two.
These things combined means that the winner in the DeWalt vs Bosch miter saw shootout is the DeWalt DWS780.
The Bosch has one added advantage in that the omission of a rail based system means you do not require a huge amount of room to the rear of the saw. So if you have a small wood shop or garage then you may find it a more suitable choice based on that.
