Description
The DEWALT 12-inch sliding compound miter saw is designed for carpenters, remodelers, cabinetmakers, and contractors who need versatile cutting capacity for demanding woodworking projects. Model DWS780 combines a sliding rail system, dual-bevel functionality, and integrated XPS cut-line positioning to help you make accurate crosscuts, miters, and bevel cuts. Its corded design provides dependable power for workshop tasks and professional jobsite applications.
Features of the DEWALT 12-Inch Sliding Compound Miter Saw
The DWS780 uses a 15-amp motor with a no-load speed of 3,800 RPM. Its 12-inch blade supports a range of cutting tasks involving dimensional lumber, trim, baseboards, and crown molding. The sliding mechanism allows the blade assembly to travel across wider workpieces, while the dual-bevel design lets you tilt the blade in either direction without repeatedly flipping the material.
The integrated XPS cut-line positioning system projects a shadow of the blade onto the workpiece, helping you see the cutting path before making a cut. This system supports alignment without requiring a separate laser adjustment. For detailed trim work and repeated cuts, clear cut-line visibility can help you position material more confidently.
Adjustable Angles and Large Cutting Capacity
The saw offers miter adjustments up to 50 degrees left and 60 degrees right, with bevel capacity reaching 49 degrees in both directions. Its tall sliding fences support crown molding up to 7-1/2 inches nested and base molding up to 6-3/4 inches vertically against the fence. Actual capacity depends on the workpiece dimensions and cutting configuration.
The stainless-steel miter detent plate and positive stops help you set common angles efficiently. A cam-lock miter handle supports quick adjustments, while the depth stop allows controlled groove and rebate cutting when configured according to the manual. These features make the saw useful for finish carpentry, flooring trim, framing components, and custom woodworking.

Safe Operation and Maintenance
Wear eye and hearing protection, secure the workpiece, and support long materials properly. Keep hands clear of the blade path, and complete an unpowered test movement before making a cut. Wait until the blade stops completely before raising the saw head or clearing debris. Disconnect power before changing the blade or performing maintenance, and follow the manufacturer’s instructions.
Choose the DEWALT DWS780 when your projects require broad cutting capacity, adjustable angles, and visible cut-line alignment. Its sliding design and dual-bevel operation make it a practical option for professional trim work and general woodworking.
