TechGearLab found the DeWalt DWS715 achieved a perfect 10.0 score for Precision and Accuracy, attributing this stability to its non-sliding design which eliminates rail wobble during dense material cuts. Handymansworld highlighted the powerful 15-amp motor that delivers up to 4,000 RPM no-load speed, enabling fast slicing through hardwoods without bogging down under load. However, the tool's fixed blade path limits cross-cut capacity to an 8.1-inch maximum at 90 degrees, preventing single-pass cuts on wider boards like 2x10s or 4x4 posts. Weighing only 36 lbs with a built-in carry handle, it offers high portability for contractors but may require external vacuum support due to modest onboard dust collection.

Strengths
  • — Rated #4 of 12 miter saws by TechGearLab with a perfect 10.0 score for Precision and Accuracy.
  • — Features a powerful 15-amp motor that delivers up to 4,000 RPM no-load speed for fast cutting.
  • — Includes an adjustable stainless steel miter detent plate with 14 positive stops for flexible angle selection.
Watch-outs
  • — Non-sliding design limits cross-cut capacity to an 8.1-inch maximum at 90 degrees.

The DeWalt DWS780 delivers powerful cutting performance through its 15-amp motor and XPS shadow alignment system, which Bob Vila found superior to traditional laser guides. TechGearLab measured the maximum cut capacity at 90 degrees as 13.6 inches, confirming its ability to handle wide stock for cabinetry projects. However, the tool weighs between 58 and 61 pounds, making it a stationary unit that is difficult to transport frequently. Dust collection performance is rated as average by reviewers, often requiring a connected vacuum to manage debris effectively. Additionally, plastic hinges on the sliding rail have been noted by users as potential durability concerns prone to damage. This miter saw fits dedicated workshop environments where stability and precision are prioritized over mobility.

Strengths
  • — Powered by a 15-amp motor running at 3,800 RPM to handle demanding cuts through dimensional lumber and trim.
  • — Features the XPS crosscut positioning system that uses an LED light to cast a blade shadow for precise alignment without calibration drift.
  • — Equipped with double-bevel capability allowing tilts up to 49 degrees left and right for efficient compound crown molding cuts.
Watch-outs

How they stack up

DeWalt DWS715

The DeWalt DWS715 achieves perfect precision scores due to its non-sliding design, which eliminates rail wobble compared to sliding models like the Makita LS1019L and DEWALT DCS361B. It offers a faster 4,000 RPM motor than the slower Makita LS1019L but sacrifices cross-cut capacity, limiting it to an 8.1-inch maximum unlike the wider cutting abilities of the DeWalt DWS780.

DeWalt DWS780

The DeWalt DWS780 features a powerful XPS crosscut positioning system that reviewers found superior to the laser guides used by the Makita LS1019L and SKIL MS6305-00. It provides a substantial 13.6-inch cut capacity at 90 degrees, far exceeding the non-sliding DeWalt DWS715, but its heavy weight of 58 lb makes it less portable than the cordless DEWALT DCS361B.
