Quick Answer
If you need constant power for heavy framing or long rip cuts, the corded Dewalt DWS535B delivers 4,800 RPM and an electric brake in a lightweight magnesium housing. For jobsite portability without a generator, the Dewalt DCS577X1 (60V MAX brushless cordless) provides corded-like performance and up to 53° of bevel capacity. Choose corded for unlimited runtime and lower upfront cost; choose cordless for unrestricted movement and convenience.

Cordless Model: DCS577X1 (and DCS577B tool-only)
- Power source: DEWALT FLEXVOLT 60V MAX battery.

Key Differences
| Feature | Corded (DWS535B) | Cordless (DCS577X1/DCS577B) |
|---|---|---|
| Power source | Corded (outlet) | 60V MAX battery |
| Weight | Lightweight magnesium | Heavier (battery adds weight) |
| Runtime | Unlimited | Limited to battery charge |
| RPM | 4,800 | Not specified |
| Bevel stops | Not listed in sources | 45° and 22.5° |
| Starting cost | Lower (tool only) | Higher (kit includes battery) |
The cordless model sacrifices some power consistency for portability, while the corded model delivers uninterrupted speed but tethers you to a power source.
Practical Takeaways
- For continuous framing with power access: Choose the corded DWS535B – proven 4,800 RPM motor and electric brake at a lower price.
- For roof work or remote jobs: Choose the cordless DCS577X1 (or DCS577B tool-only if you own FLEXVOLT batteries). The 53° bevel range and rafter hook aid ladder work.
- Bevel cuts: The cordless saw has dedicated stops at 45° and 22.5° for fascia and trim; the corded model may need aftermarket adjustment.
- Battery investment: New to FLEXVOLT? The kit (DCS577X1) includes a battery and charger; otherwise, the tool-only (DCS577B) saves money.
