The best DeWalt skill saw for most framing and full-time jobsite use is the 60V MAX FLEXVOLT 7-1/4-inch DCS570 or worm-drive style DCS577, while the 20V MAX 7-1/4-inch DCS573 and compact 6-1/2-inch DCS565 are better matches for remodeling, punch-list work, and shop use where weight and battery commonality matter more than absolute power. Corded models like the DWE575SB still win for continuous shop cutting on a budget.

DeWalt Skill Saw Lineup at a Glance
DeWalt uses “skill saw” and “circular saw” interchangeably, but all of its current saws are sidewinder or worm-drive-style circular saws. The real split is power source and blade diameter, which determines cut depth, weight, and which battery system you are buying into.
- Corded 7-1/4-inch (DWE575SB, DWE575): 15-amp motor, lightest corded option, no battery cost.
- 60V MAX FLEXVOLT 7-1/4-inch (DCS570B, DCS577B / DCS577X1): Full-size performance intended to replace corded for framing. DCS570 is standard sidewinder, DCS577 is worm-drive style with rear handle and blade-left orientation.
- 20V MAX 7-1/4-inch (DCS573B): Brushless sidewinder that runs on standard 20V MAX batteries, slightly less power than 60V but lighter and cheaper if you already own 20V tools.
- 20V MAX 6-1/2-inch (DCS565B, DCS391B): Compact, one-handed saws for remodelers, trim carpenters, and shop crosscutting. Can be run all day on a 5.0Ah 20V battery.
- 20V MAX ATOMIC 4-1/2 to 5-3/8-inch (DCS512B): Ultra-compact trim and underlayment saw, not a full-depth framer.
Spec Comparison: Concrete Numbers That Affect the Cut
Marketing watts and RPM only tell part of the story. Weight, depth of cut at 90 and 45 degrees, and bevel capacity determine whether you can make a single-pass cut on doubled lumber or safely handle the saw overhead.
| Model | Power Source / Platform | Blade Size | No-Load RPM | Cut Depth at 90° | Cut Depth at 45° | Bevel Capacity | Bare Tool Weight |
|---|---|---|---|---|---|---|---|
| DWE575SB | Corded 15A (120V) | 7-1/4 in | 5,200 | 2-9/16 in (65mm) | 1-7/8 in (48mm) | 57° with stops at 22.5°/45° | 8.8 lbs |
| DCS570B | 60V MAX FLEXVOLT | 7-1/4 in | 5,800 | 2-9/16 in (65mm) | 1-7/8 in (48mm) | 57° | 9.2 lbs (without battery) |
| DCS577B (Worm Drive Style) | 60V MAX FLEXVOLT | 7-1/4 in | 5,800 | 2-7/16 in (62mm) | 1-3/4 in (44mm) | 53° | 9.5 lbs (without battery) |
| DCS573B | 20V MAX | 7-1/4 in | 5,500 | 2-7/16 in (62mm) | 1-3/4 in (44mm) | 57° | 8.8 lbs (without battery) |
| DCS565B | 20V MAX | 6-1/2 in | 4,950 | 2-1/8 in (54mm) | 1-5/8 in (41mm) | 50° | 6.9 lbs (without battery) |
| DCS512B ATOMIC | 20V MAX | 5-3/8 in | 4,500 | 1-3/8 in (35mm) | 1 in (25mm) | 46° | 5.1 lbs (without battery) |
All 7-1/4-inch models will cut a 2×4 at 90° in one pass and a doubled 2x material stack (3 inches) only with the corded DWE575SB or DCS570 at full depth. The 6-1/2-inch DCS565 clears a 2×4 at 90° but requires a flip-cut for 4×4 posts. Blade-left saws like the DCS577 give right-handed users a clearer sightline to the cut line when the saw is on a rafter or joist, which is why many framers prefer that layout despite the slightly higher weight.
Cordless vs Corded: Power, Runtime, and Real Cost to Own
1. Power and Feel
The corded DWE575SB delivers continuous 15-amp torque without voltage sag, so it holds speed better in wet pressure-treated lumber and dense LVL. The 60V FLEXVOLT saws come closest to that feel because the 60V battery (which steps down to 20V in other tools) can deliver higher sustained current. The 20V DCS573 will rip 3/4-inch plywood and cut SPF framing cleanly, but it bogs sooner in 2×10 and 2×12 bevel cuts, especially with a dull or 24-tooth framing blade.
2. Runtime Worked Example
Runtime is not just amp-hours. Use this quick estimate before you buy batteries:
Formula: Usable cuts per charge ≈ (Battery Wh × 0.85 efficiency) / (Cut energy in Wh)
A DeWalt 20V 5.0Ah battery holds about 90Wh (20V × 5.0Ah × 0.9 nominal voltage factor), a FLEXVOLT 9.0Ah / 60V battery holds about 108Wh when used at 60V. A typical crosscut in SPF 2×4 with a sharp 24T blade uses roughly 0.8 to 1.1Wh. That yields:
- 20V 5.0Ah + DCS565 (6-1/2-inch): ~70 to 95 crosscuts in 2×4, or ~35 linear feet of rip in 3/4-inch plywood
- 20V 5.0Ah + DCS573 (7-1/4-inch): ~60 to 80 crosscuts, because the larger blade and higher load draw more current
- 60V 9.0Ah + DCS570/DCS577: ~90 to 120 crosscuts in 2×4, or ~45 to 55 linear feet of plywood rip
In practice, framers get a half day of cut-and-carry work from one 9.0Ah FLEXVOLT and a full day from two batteries if they also use the saw for occasional bevel rips. Remodelers doing intermittent cuts can run a DCS565 all day on two 5.0Ah 20V packs because idle time lets batteries cool and recover.
3. Battery Platform Strategy
If you already own DeWalt 20V MAX tools, the DCS573 or DCS565 keeps you on one charger and one battery size. FLEXVOLT batteries work in both 60V and 20V tools, but they are heavier, larger, and more expensive to replace. Buying into 60V only makes sense if you need the extra depth and sustained power for framing, decking, or timber work. For a shop that already has 120V on the wall, a corded DWE575SB avoids battery replacement cost entirely and typically costs significantly less upfront than any bare cordless saw plus battery and charger.
Decision Matrix: Match the Saw to Your Situation
| Your Situation | Best Match | Why |
|---|---|---|
| Framing, decks, pergolas, 2×10+ rafters. Cutting all day, often outdoors. | DCS570B or DCS577B with 60V 9.0Ah or 12.0Ah | Full 2-9/16-inch depth, holds speed in thick cuts, blade-left option for sightline. Bring two batteries and a fast charger. |
| Remodeling, punch work, overhead soffits, demo. Need one-hand control. | DCS565B 6-1/2-inch 20V MAX | Nearly 2 lbs lighter than 7-1/4-inch, easier overhead, uses common 20V batteries. Still cuts 2x material at 90°. |
| Shop use, plywood breakdown, furniture, limited budget. | DWE575SB Corded 7-1/4-inch | No battery degradation, continuous power, electric brake and integrated dust blower. Add a good 40T or 60T blade for clean plywood. |
| Already heavily invested in 20V MAX, occasional 7-1/4-inch needs | DCS573B 20V MAX 7-1/4-inch | Avoids buying into FLEXVOLT. Good compromise power for sheet goods and 2x cutting without adding a new platform. |
| Tight spaces, flooring, underlayment, trim, crawlspaces | DCS512B ATOMIC Compact | One-handed, minimal kickback leverage, but not for 2x framing. Depth limited to 1-3/8 inches. |
Ownership Realities Most Listings Skip
Understanding what wears first saves more money than chasing a small RPM difference.
- Base plate and depth lock: DeWalt’s aluminum and magnesium shoes hold flat if you do not drop the saw. The depth lever and bevel lock are the first to loosen. Check them monthly and keep sawdust out of the threads. A saw that slips 1/16-inch during a rip will bind the blade.
- Blade guard return: Pitch buildup on the guard pivot slows the guard, which is a kickback hazard. Blow out dust after each day and wipe the guard with dry lube, not oil that attracts dust.
- Brushless motor vs brushed: All current DeWalt cordless skill saws and the DWE575SB’s newer production are brushless or use long-life motors, so brushes are not a routine consumable. The consumables are blades, batteries, and shoe inserts.
- Batteries: Heat kills lithium cells. Do not charge a hot battery straight off the saw in summer sun. Let it cool 15 minutes. Store at 40-60% charge if you will not use the saw for weeks. Expect 300 to 500 full cycles before noticeable capacity loss.
- Common mistakes: Using a 24-tooth framing blade for finished plywood causes tear-out and burning. Using a fine 60-tooth blade for framing causes slow cuts and overheating. Keep two blades: a 24T rip/framing blade and a 40T or 60T crosscut/plywood blade. Also, never defeat the guard or use a damaged cord/battery case.
- Noise and dust: All 7-1/4-inch saws are 95+ dB under load. Hearing protection is not optional. Cordless saws throw the same fine dust as corded; cut outside or connect to dust extraction when working indoors.
Quick Setup for Straight Cuts Every Time
A skill saw DeWalt or otherwise will only cut as straight as its calibration: one minute of checking prevents a day of binding.
- Unplug or remove the battery, set depth so 1/4-inch of tooth shows below the material, this reduces exposed blade and kickback.
- Check 90° with a speed square against the blade body (not the teeth) and the shoe. Adjust the 0° stop screw if needed, then verify 45° with the square.
- Align the notch indicator to a test cut scrap, not just the printed guide. Mark the kerf side and keep waste side to the open side of the shoe.
- Support the keeper side of the board. Let the cutoff fall free. Clamping the cutoff causes the blade to pinch at the end of the cut.
Which Skill Saw DeWalt Should You Choose?
If you can only own one DeWalt skill saw in 2026, choose by where you cut, not just by voltage.
- Buy the DCS570B or DCS577B if you frame, build decks, or cut engineered lumber weekly and need true corded replacement power. Budget for at least one FLEXVOLT 9.0Ah battery and the dual-voltage charger.
- Buy the DCS573B if you want a full-size 7-1/4-inch saw but live on 20V MAX batteries. It handles 90% of jobsite cuts and is lighter on the wallet than the 60V system.
- Buy the DCS565B 6-1/2-inch if you prioritize weight and maneuverability for remodeling, rental work, or shop crosscuts and can accept a slightly shallower depth.
- Buy the DWE575SB if the saw lives in the shop, you have reliable power, and you want the lowest long-term cost with no battery maintenance.
Across all of them, invest in sharp, appropriate blades and a solid straight-edge guide. That will improve cut quality more than any single model upgrade, and it keeps any DeWalt skill saw cutting safely and accurately for years.
