How to choose
Compatibility with DeWalt 20V Batteries
When selecting a cordless circular saw, verify the power source compatibility. Several options listed, such as the DCS391B and the 6-1/2 inch brushless model (B0H9RVT84G), are sold as tool-only units, meaning they are designed to operate using your existing DeWalt 20V battery ecosystem. Conversely, the DCS391L1 kit includes a 3.0 Ah battery, providing a complete out-of-the-box solution. Always confirm if your purchase includes a battery or if you need to provide your own 20V power cells to ensure the tool functions immediately upon arrival. Check the product specifications carefully to avoid purchasing a tool that requires an additional power investment if you do not already own compatible batteries.
Motor Type and Performance
Circular saws in this category feature either standard motors or brushless motor technology. Brushless models, such as the 7-inch cordless saw (B0GY4Y2YD5) and the 6-1/2 inch high-RPM model (B0GXZ1FFPX), generally offer efficiency advantages. These saws range in rotational speed, with some units reaching up to 8000 RPM, while others operate at 5150 RPM or 5900 RPM. Higher RPM ratings often correlate with faster cutting speeds through materials like wood and PVC. Consider the intensity of your cutting projects when choosing between these motor configurations, as brushless motors are frequently associated with modern, high-performance cordless power tool designs suitable for various workshop and construction applications.
Blade Size and Cutting Depth
Blade diameter directly influences the maximum cutting depth of the circular saw. Options include 6-1/2 inch blades, which typically provide a cutting depth between 2 and 2-1/5 inches at 90 degrees, and 7-inch blades, which offer a deeper 2-3/8 inch cutting capacity. If your projects involve thicker lumber or deep material cross-cuts, a 7-inch blade provides a distinct advantage. Conversely, 6-1/2 inch saws are often lighter and more maneuverable for standard workshop tasks. Always match the blade size and specified cutting depth to the thickness of the materials you intend to cut to ensure clean, consistent performance across all your woodworking or PVC cutting requirements.
Bevel Capacity and Adjustability
Bevel capability allows for angled cuts, which are essential for mitered joints and specialized joinery. Most models, including the 6-1/2 inch brushless saw (B0H9RVT84G) and the 7-inch cordless model (B0GY4Y2YD5), feature a 0-45 degree bevel range. The DCS391B offers an expanded 0-50 degree range for greater versatility, while the 6-1/2 inch 8000 RPM model lists a 0-90 degree range. Consider the specific angles required for your woodworking projects when evaluating these tools. A wider bevel range provides more flexibility for complex cuts. Ensure the adjustment mechanisms are clearly marked and easy to operate to maintain precision during your cutting tasks.
Included Accessories and Portability
Evaluate what comes in the box beyond the tool itself. Some models, like the 6-1/2 inch brushless saw (B0H9RVT84G), include a tool bag for storage and transport. Others, such as the 7-inch cordless saw (B0GY4Y2YD5), come with multiple TCT blades, including 40T and 24T options for different cutting finishes. The 6-1/2 inch 8000 RPM model includes a rip guide and hex wrench, which are vital for straight, repeatable cuts. Assessing these extras can save you money and time, as you will not need to purchase separate blades, guides, or storage solutions immediately upon acquiring your new circular saw for your workshop.
Frequently asked questions
Can I use Flexvolt batteries with these 20V circular saws?
The products listed are identified as being compatible with DeWalt 20V battery systems. While the user keyword mentions Flexvolt, the product names specify compatibility with the 20V Max platform. Because DeWalt 20V Max tools are generally designed to accept the 20V/60V Flexvolt battery line due to their backwards compatibility, these saws should typically function with Flexvolt batteries. However, always refer to the specific tool's manual or product listing to confirm that your specific battery model is supported for safe and optimal operation.
Does the DCS391B come with a battery?
No, the DCS391B 20V MAX Circular Saw is sold as a tool-only unit. The product name explicitly states 'Battery Not Included.' This model is intended for users who already own DeWalt 20V MAX batteries and chargers. If you do not already possess these items, you would need to purchase them separately to operate the tool. If you prefer a kit that includes a battery, consider the DCS391L1, which is listed as a 3.0 Ah circular saw kit.
What is the difference between the 6-1/2 inch and 7 inch saws?
The primary difference is the blade size, which dictates the maximum cutting depth. The 6-1/2 inch models generally provide a cutting depth ranging from 2 to 2-1/5 inches at 90 degrees. The 7-inch cordless model offers a deeper cutting capacity of 2-3/8 inches. Choosing between them depends on the thickness of the materials you frequently cut. If you regularly work with thicker dimensional lumber, the 7-inch saw provides the extra depth capacity required for those specific applications.
Do these circular saws include blades?
Yes, all the circular saws listed in the provided records include at least one blade. For example, the 7-inch cordless saw (B0GY4Y2YD5) includes three TCT blades (two 40T and one 24T), while the 6-1/2 inch brushless model (B0GXZ1FFPX) comes with a 30T TCT blade. The inclusion of blades allows you to begin cutting wood or PVC shortly after assembly. Always check the individual product description to confirm the specific count and type of blade included with your purchase.
What does 'Brushless' mean for these circular saws?
Brushless motor technology, featured in models like the B0GY4Y2YD5 and B0H9RVT84G, typically offers increased efficiency compared to traditional brushed motors. These motors are designed to reduce friction and heat, which can lead to longer tool life and potentially improved battery runtime during use. When shopping for a circular saw, opting for a brushless model is a common choice for users looking for modern motor performance in their cordless power tools, specifically for consistent output during demanding cutting tasks in wood or PVC.
Bottom line
For users seeking the most robust cutting capacity within the 20V ecosystem, the 7-inch Cordless Circular Saw (B0GY4Y2YD5) stands out as the strongest fit. Its brushless motor combined with a 2-3/8 inch cutting depth provides the versatility needed for thicker materials that standard 6-1/2 inch models may struggle with. Furthermore, the inclusion of three TCT blades—two 40T for finer finish work and one 24T for faster, rougher cuts—adds significant value for diverse projects. For professionals or serious hobbyists who prioritize deep cuts and motor efficiency without needing to source extra blades immediately, this model offers a comprehensive and high-performance solution that leverages existing DeWalt 20V battery power effectively.
Deciding between these models depends primarily on your specific cutting requirements and current inventory. If you already own DeWalt batteries, focus on the tool-only options like the DCS391B for a straightforward, reliable sidewinder experience or the B0H9RVT84G for added accessories like a tool bag. If you are starting from scratch, the DCS391L1 kit is the most logical choice because it includes the necessary 3.0 Ah battery. Finally, compare the maximum RPM and bevel range of your top choices; prioritize the 8000 RPM brushless models for high-speed production, or the 6-1/2 inch models if weight and compact portability are the most important factors for your daily workshop tasks.
