Our Take

Best for: Professional framers, finish carpenters, and serious woodworkers.

The DEWALT DWS780 is a top-tier 12-inch sliding compound miter saw built for demanding jobs. Its 15-amp motor spins at 3,800 rpm, easily cutting through hardwoods and pressure-treated lumber. The XPS crosscut positioning system projects an LED shadow of the blade line, eliminating the need for laser alignment while staying accurate. The double bevel design lets you tilt left or right for complex crown molding cuts without flipping the workpiece. The sliding fence supports nested crown up to 7-1/2 inches and base molding vertically. The dust collection system captures over 75% of debris, keeping your workspace cleaner than many competitors. At 58 pounds, it's not the lightest, but the built-in carry handles and compact rail design make it manageable for job site use. The stainless steel detent plate with 10 positive stops ensures repeatable miter angles. For the price, this is one of the best values in its class.

Price Analysis

At $424.99, this is 37% off the original $669.99 MSRP. This price is near the all-time low for the DWS780, which typically sells for $500-$600. It's an excellent time to buy if you need a pro-grade sliding miter saw.
