DEWALT 20V MAX 6-1/2 in. Sidewinder Circular Saw
Strengths
- Affordable tool-only price
- Magnesium shoe for durability
- Keyless blade change
- 3-year warranty
- Comfort grip
Trade-offs
- Brushed motor
- No dust collection
- No LED light
The DCS391B is DeWalt’s no-frills, budget-friendly 6-1/2-inch saw, and it gets the job done without flash. It’s built around a brushed motor, which means less efficiency and shorter lifespan than brushless models, but it still spins at 5,150 RPM and cuts through 2x material without issue. The magnesium shoe is durable and keeps weight down, and the keyless blade change is a real time-saver. This is the kind of tool you toss in a truck bed and don’t worry about.
Owners say it’s reliable for light to medium tasks, but it’s not built for marathon sessions. Compared to the DCS565B, it lacks brushless efficiency and dust management, but it’s significantly cheaper. If you’re on a tight budget and only cutting occasionally, this is a smart way in.

DEWALT 20V MAX 6-1/2 in. Circular Saw Kit
Strengths
- Includes 5.0-Ah battery
- Comes with charger
- Good entry-level price
- Keyless blade change
- Magnesium shoe
Trade-offs
- Brushed motor
- No brushless efficiency

How We Tested dewalt cordless circular saws
Rather than a hands-on lab test, my research focused on a detailed comparison of specifications and features across the Dewalt cordless circular saw lineup. I weighed published data against owner reviews from multiple sources and insights from other power tool experts. This allowed me to rank each saw based on its intended use and overall value, considering everything from motor power to included accessories.
For Dewalt circular saws, runtime, power, and cutting capacity were the most significant factors. Dewalt’s FLEXVOLT models consistently stand out for their increased power, making them ideal for demanding jobs. Brushless motors also heavily influenced rankings, as they offer improved efficiency and longer tool life. Finally, overall kit value played a role, particularly for those starting out.
Specifications clearly indicate motor power (measured in RPM and voltage) and maximum cut depth. However, owner feedback provided crucial context regarding real-world performance and durability. I paid close attention to reports of battery life, ease of use, and long-term reliability. Understanding circular saw operation basics is also key to interpreting user experiences and identifying saws suited to different skill levels.
Choosing The Right dewalt cordless circular saws
Choosing the right circular saw involves more than just grabbing the one with the biggest motor.
A quality circular saw balances power with control and features suited to the user’s typical tasks. Key considerations include motor voltage (affecting power and runtime), blade size (determining cutting depth), weight and ergonomics (for comfort and maneuverability), and safety features like electric brakes. Look for models with positive bevel stops and clear scales for accurate angled cuts.
Motor Voltage and Battery Platform
Don’t underestimate the importance of the battery platform. While 20V MAX tools are fine for lighter work, stepping up to 60V FLEXVOLT offers a noticeable power boost, especially when dealing with thicker materials. If you already own a range of tools within a specific voltage family (like DeWalt’s 20V MAX), sticking with that platform avoids the cost and clutter of multiple battery chargers and batteries. Consider how frequently you’ll be using the saw; for occasional tasks, a 20V model might suffice, but professionals or those tackling demanding projects will quickly appreciate the extra muscle of 60V.
Blade Size and Cutting Capacity
The blade size dictates the maximum cutting depth and the types of materials you can effectively handle. A 7-1/4 inch blade is the most common size, offering a good balance between power and versatility, and is essential if you frequently cut sheet goods like plywood or OSB. Smaller 6-1/2 inch blades provide increased maneuverability in tight spaces but sacrifice cutting depth. Here’s how blade size impacts your options:
- 4-1/2 inch blades: Ideal for small projects and portability.
- 6-1/2 inch blades: A good compromise for general use and tighter spaces.
- 7-1/4 inch blades: Best for ripping sheet goods and making deeper cuts. This is what you’ll want if you’re framing walls or doing a lot of carpentry.
A good rule of thumb: match the blade to the material. Thicker, denser materials require larger blades and more powerful motors.
Ergonomics and Features
Beyond power, a comfortable and well-designed saw will improve accuracy and reduce fatigue. Look for features like a rubberized overmold grip, a well-positioned blade guard, and a clear line of sight to the blade. An electric brake is a must-have; it stops the blade quickly after you release the trigger, enhancing safety and preventing overcuts. Integrated LEDs can illuminate your cut line, particularly helpful in dimly lit work areas. If you’re considering a kit, check what’s included, some kits offer multiple batteries, a charger, and even a carrying case. Before making a final decision, read through best DeWalt saw reviews to see what other users are saying about specific models. And remember, knowing how to replace circular saw blade is a critical skill for any circular saw owner.
