The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the DEWALT DCS785B is the cordless saw to buy when you actually need 12" capacity. protoolreviews.com, a high-trust expert source, concludes it "proves itself to be a robust and highly capable cordless miter saw, offering power and precision that rivals corded models," and praises the smoothness of the slide vs. entry-level competitors.
What reviewers liked
- High-trust review from protoolreviews.com calls it competitive with corded saws
- Largest cordless capacity in this ranking (up to 14" horizontal, 6-1/2" crown nested)
- r/Dewalt community calls it a DCS781 clone, a saw with strong reputation
- Double-bevel design unlike the fixed DCS714B
Where it falls short
- Heavy and bulky, flagged repeatedly in r/Dewalt threads
- Lower runtime per charge than the 60V FlexVolt equivalent per Reddit benchmarks
- Thin Amazon sample (31 reviews) limits customer-side signal strength
- Bare-tool price assumes high-capacity DEWALT 20V battery already in the kit
Across the reviewers we read, the DEWALT DCS785B is the cordless saw to buy when you actually need 12" capacity. protoolreviews.com, a high-trust expert source, concludes it "proves itself to be a robust and highly capable cordless miter saw, offering power and precision that rivals corded models," and praises the smoothness of the slide vs. entry-level competitors. Multiple r/Dewalt threads call it a near-carbon-copy of the 60V DCS781 FlexVolt saw, which the community broadly respects.
The consensus pushback is weight and bulk. One r/Dewalt thread we read summarizes it plainly: "the 7-1/4" is too small and the 12" is heavy and bulky." Runtime is also platform-dependent; r/Dewalt benchmarking discussion cites roughly 153 cuts in a 4x4 with an 8Ah battery vs. 255 cuts on the 60V FlexVolt cousin, so buyers chasing maximum runtime per charge may want the FlexVolt platform instead.
The Amazon sample is thin (31 reviews) so the score leans more heavily on the high-trust expert verdict and community discussion than on customer volume. For wide trim, crown nested at 6-1/2", and 2x12 crosscuts, reviewers agree this is the cordless answer on the 20V MAX platform.

Between the two it's only about 5 lbs difference. A 10" would be perfect. The 7-1/4" is too small and the 12" is heavy and bulky. Home Depot has ...
The new 20v 12" dual bevel slider looks to be a carbon copy of its 60v cousin. Which is not a bad thing, as the 781 is a unit.
