From fine cabinetry and furniture making to building decks and framing walls, the DeWalt DWS780 12'' Sliding Compound Miter Saw has the capacity, portability and accuracy to get the job done right. It pairs rugged construction with precision features such as the XPS cut alignment system, which projects a neat line on the board showing exactly where the blade will cut. Unlike conventional laser guides, the system requires no adjustments, even after blade changes. Castings for the fence and bevel system are precision machined, while the miter detent plate is made from stainless steel to hold up to tough jobsite use. A 15A, 3,800 RPM motor delivers abundant power to cut through thick dimensional lumber. Cut capacities are very generous: 6-3/4'' of vertical baseboard capacity, 7-1/2'' of nested crown capacity, 13-7/8'' of horizontal capacity. The miters can be adjusted up to 60° to the right and 50° to the left. The head can also be angled to make bevel cuts of up to 49° right or left with positive stops at 0°, 22.5°, 33.9°, 45°, and 49°.


  • Integrated Blade Positioning System provides adjustment-free cut line indicator for easy alignment with your pencil marks
  • 15 amp, 3,800 RPM motor delivers abundant power and durability
  • Ultra-efficient dust collection system captures over 75% of dust generated
  • Tall sliding fences support crown molding up to 7-1/2'' nested and base molding up to 6-3/4'' vertically against the fence
  • Fences slide easily out of the way for bevel cuts
  • Exclusive back fence design cuts up to 2x16 dimensional lumber at 90° and 2x12 at 45°
  • Adjustable stainless steel miter detent plate with 10 positive stops for improved accuracy and quick setups
  • Angles 60° to the right and 50° to the left for tight miters, even if the corner is slightly over 90°
  • Oversized bevel scale makes bevel angle adjustments accurate and easy
  • Compact, lightweight design (only 56 lbs.) for easy transport and storage
  • Cam lock miter handle with detent override delivers quick and accurate miter angles
  • Dual horizontal steel rails with innovative clamping mechanism and linear ball bearings
  • Innovative gearbox and belt-drive design increases vertical cutting capacity

Great new addition to our shop
We had an old strictly chop saw before, so all the features on this on really helps the flow in our shop. I would like to see an improvement in the dust collection system, but we’re figuring out an alternate way to help get more dust and chips into the shop wide vacuum system.

does this saw have laser guides?
Mark F on Jan 18, 2019
BEST ANSWER: Not a laser, but a light over the blade that casts a shadow of the blade exactly where it will cut. I like it a lot.
