Best OverallPros
- Excellent power for ripping and crosscutting
- Works with 20V and 60V batteries
- Worm-drive style gearing for torque
Cons

- Premium price point
The DCS578X2 is DeWalt's most powerful cordless circular saw, using the FlexVolt system to deliver 60V of cutting force.

The integrated rafter hook and bright LED light are practical additions for jobsite use.
This saw is best for framers and heavy remodelers who need maximum runtime and cut capacity. The included 9.0Ah battery provides long work sessions, but the weight is noticeable for overhead cuts. It is a serious tool for serious work.
DeWalt DCS391B 20V MAX
Best BudgetPros
- Very lightweight and easy to handle
- Affordable price for DIY users
- Compatible with all 20V MAX batteries
Cons
- Brushed motor less efficient
- 6-1/2 inch blade limits cut depth
The DCS391B is a popular entry-level cordless saw that offers good value for homeowners and light DIY projects. Its compact size and low weight make it easy to use one-handed for quick cuts on plywood and 2x lumber. The magnesium shoe is a nice touch for durability at this price.
While it lacks the power of the FlexVolt models, it handles standard framing lumber well. Owners note the dust blower keeps the cut line visible. It is a solid choice for anyone who already owns 20V DeWalt tools and needs a budget-friendly saw.
DeWalt DCS573X1 20V MAX
Best Compact PowerPros
- Brushless motor for efficiency
- Full 7-1/4 inch blade in a compact body
- Excellent dust collection port
Cons
- Only one battery included
- Not as powerful as FlexVolt models
The DCS573X1 bridges the gap between the budget DCS391 and the heavy-duty FlexVolt saws. It features a brushless motor for longer runtime and a full-size 7-1/4 inch blade that can cut through thicker materials. The compact design makes it easier to maneuver in tight spaces.
Owner reviews highlight the smooth cutting action and the effective electric brake. It is a great all-around saw for both DIYers and professionals who want a balance of power and portability. The included 5.0Ah battery provides decent runtime for most tasks.
DeWalt DWE575SB
Best Corded PrecisionPros
- Consistent power with no battery drain
- Lightweight for a corded saw
- Excellent cut line visibility
Cons
- Requires a power outlet
- Cord can be a tripping hazard
The DWE575SB is a lightweight corded saw that delivers consistent power for precision cuts. Its 15-amp motor provides ample torque for ripping hardwood and cutting thick stock. The integrated dust blower and bright LED light keep the cut line clear.
This saw is ideal for workshop use where a power outlet is always available. It is lighter than many corded competitors, reducing fatigue during extended use. Owners appreciate the durable construction and the easy-to-adjust bevel and depth settings.
DeWalt DCS577X2 FlexVolt 60V
Best for Deep CutsPros
- Deep cut capacity for thick materials
- Powerful FlexVolt system
- Durable construction
Cons
- Heaviest saw in the lineup
- Overkill for standard lumber
The DCS577X2 is designed for cutting thick beams and stacked materials. Its unique blade placement allows for a 3-1/2 inch cut depth at 90 degrees, making it suitable for cutting 4x4 posts in a single pass. The FlexVolt system provides the necessary power for these demanding cuts.
This saw is a specialist tool for heavy timber framing and deck building. Owner reviews note the excellent build quality and the smooth cut even under load. The weight is significant, but it is a trade-off for the extra cut capacity.
What to check before buying a DeWalt circular saw
Consider your typical material thickness. A 6-1/2 inch saw will cut 2x lumber at 45 degrees, but a 7-1/4 inch saw offers more versatility. Battery voltage is also important: 20V models are lighter, while 60V FlexVolt models provide more power and runtime. Check the bevel capacity if you need angled cuts, and look for features like an electric brake and LED light for safety and convenience.
Mistakes to avoid
Do not buy a saw based solely on price. A very cheap model may have a brushed motor that drains batteries quickly and lacks power. Avoid skipping the blade upgrade, as the included blade is often basic. Also, do not overlook the weight of the saw with a battery attached, as a heavy saw can cause fatigue during extended use.
