Overview
The DEWALT DWS780-QS is a 12 inch corded miter saw running on 110 volts at 3800 RPM, with a 1675 watt motor. At nearly 55 pounds, it's built as a stationary shop tool rather than something carried between job sites daily.
This model matches DEWALT's 12 inch double bevel sliding compound miter saw line, a tool built for cutting crown molding, baseboard and framing lumber at precise angles. The high speed steel reference in the spec sheet points to the blade material rather than the saw body, which is typically aluminum and steel.
- Brand: DEWALT
- Power: 1675 watt corded electric motor
- Blade capacity: 12 inches
- Weight: 24.8 kilograms (about 55 pounds)
Who it's for
Suits a serious DIYer or tradesperson doing trim, framing or furniture work who needs accurate, repeatable angle cuts on a stationary saw. It's not a fit for anyone wanting a portable, battery-powered saw for occasional cuts.
Strengths and trade-offs
Drawn from this product's published specifications.
- 1675 watt motor handles hardwood and dimensional lumber
- 12 inch blade capacity cuts wider stock
- Corded power avoids battery runtime limits
- At nearly 55 pounds, it's not built for daily transport
- Requires a 110 volt outlet, so it's tied to a work station
Performance notes
A 1675 watt motor spinning at 3800 RPM gives this saw enough power to drive through hardwood and dimensional lumber without bogging down, while the 12 inch blade capacity handles wider stock than smaller compound miter saws. Running on corded 110 volt power means consistent output for as long as the saw is plugged in, without battery runtime to manage.
