How to choose
Blade Diameter and Capacity
Select a blade size based on your material thickness requirements. Options range from compact 5-1/2 inch models reaching 1.9-inch depths to 7-inch saws capable of 2-3/8 inch cuts. Larger blades like the 7-inch variant offer superior depth for heavy-duty wood and PVC projects, while smaller 5-1/2 inch versions prioritize portability for lighter tasks. Always verify the maximum cutting depth at both 90 and 45-degree angles to ensure the tool accommodates your specific lumber dimensions. Larger blades generally handle thicker stock more efficiently, whereas smaller diameters provide greater maneuverability in confined spaces or for precision trimming applications where bulk is undesirable.
Motor Technology
Brushless motor technology is a standard feature across many modern cordless circular saws compatible with DeWalt 20V batteries. These motors typically offer improved efficiency and longevity compared to brushed alternatives. When evaluating your options, look for brushless models if you prioritize consistent power delivery and extended tool life during repetitive cutting tasks. While the DCS391L1 kit includes a battery, many newer brushless options are sold as tool-only, allowing you to leverage existing 20V battery inventories. Prioritizing a brushless motor ensures you get the most out of your 20V battery runtime when tackling demanding wood or PVC cutting projects.
Bevel and Angle Adjustments
The bevel capacity determines your ability to perform angled cuts, essential for joinery and finish work. Most models, including the 5-1/2 inch, 6-1/2 inch, and 7-inch variants, offer a 0-45 degree range, while specific models may reach up to 90 degrees. Consider the precision of the scale and the ease of adjustment when selecting a saw. A versatile bevel range allows for complex cuts in wood and PVC. Ensure the locking mechanism is accessible to maintain consistent angles throughout your project. Greater bevel flexibility expands the range of applications, from basic cross-cuts to specialized mitered edges.
RPM and Performance
Rotational speed, measured in revolutions per minute (RPM), influences the speed and cleanliness of your cuts. Available models feature speeds ranging from 5900 RPM to 8000 RPM. Higher RPM ratings generally indicate faster material removal, which is advantageous for quick cuts in wood. However, balance this against the torque requirements of your specific material. A saw delivering 8000 RPM provides significant speed for production-style cutting, while models around 5900 RPM offer a steady pace for general construction. Match the RPM output to your typical workload to ensure efficient operation without sacrificing control or safety during the cutting process.
Included Accessories
Check the included package contents to determine overall value. Some saws, like the 7-inch brushless model, come bundled with multiple TCT blades, providing immediate versatility for different cutting needs. Others, such as the 6-1/2 inch model, may include a rip guide for straight-line accuracy, a hex wrench for blade changes, or a tool bag for storage and transport. The DCS391L1 is notable for being a complete kit including a 3.0 Ah battery. Evaluate whether you need a bare tool to expand your existing collection or a comprehensive kit that includes blades, storage, and power sources.
Frequently asked questions
Are all these circular saws compatible with my existing DeWalt 20V batteries?
Yes, all the listed circular saws are specifically designed to be compatible with DeWalt 20V Max battery systems. This cross-compatibility allows users to utilize their existing battery inventory across various tool-only models. Whether you choose a 5-1/2 inch, 6-1/2 inch, or 7-inch saw, the battery interface remains consistent, providing the power required for the brushless motors. Always ensure your battery is fully charged before beginning wood or PVC cutting projects to maintain optimal performance levels during operation.
Which circular saw offers the greatest cutting depth for thick materials?
The 7-inch cordless circular saw stands out with a maximum cutting depth of 2-3/8 inches. This makes it the most suitable choice among the options for users who frequently work with thicker wood stock or need to make deeper cuts in PVC. While other models offer depths ranging from 1.9 inches to 2-1/5 inches, the 7-inch model provides the most significant clearance, ensuring you can complete challenging cuts efficiently without needing to flip the material.
Do these circular saws include a battery and charger?
Most of the models listed are sold as 'Tool Only' units, meaning they do not include a battery or charger. The DCS391L1 is a notable exception, as it is sold as a complete kit including a 3.0 Ah battery. If you already own DeWalt 20V batteries, purchasing a tool-only model is a cost-effective way to add a circular saw to your workshop. Always verify the package contents before purchase to ensure you have the necessary power source.
What is the benefit of a brushless motor in these circular saws?
A brushless motor, featured in many of these saws, typically offers higher efficiency, better power-to-weight ratios, and extended tool life compared to traditional brushed motors. By reducing friction and heat during operation, brushless technology helps maximize the runtime of your 20V battery. This is particularly beneficial for demanding tasks involving wood or PVC, as the motor can adjust its power delivery to match the load, resulting in more consistent performance across a wide range of cutting applications.
Can these saws handle materials other than wood?
Yes, several of these circular saws are specifically marketed for cutting both wood and PVC. Models such as the 7-inch brushless saw and the 6-1/2 inch cordless saw explicitly mention compatibility with PVC cutting projects. The inclusion of TCT (Tungsten Carbide Tipped) blades on several models further enhances their ability to handle diverse materials cleanly. Always consult the specific tool documentation to confirm the blade type is appropriate for the density of the plastic or composite material you intend to cut.
Bottom line
For users seeking the most robust performance, the 7-inch brushless circular saw is the superior choice. Its 2-3/8 inch cutting depth provides the highest capacity among the available options, making it ideal for demanding wood and PVC projects. The inclusion of three TCT blades (two 40T and one 24T) adds significant value, offering versatility right out of the box. For those prioritizing high-speed material removal, the 6-1/2 inch model reaching 8000 RPM is an excellent contender, providing a lightweight, 6.2 lb frame that balances portability with aggressive cutting power. If you require a turn-key solution, the DCS391L1 kit remains the only option that includes a 3.0 Ah battery, serving as a reliable foundation for those new to the DeWalt 20V ecosystem.
Deciding between these models depends primarily on your depth requirements and existing battery inventory. If you need maximum capacity for thick lumber, prioritize the 7-inch model. For general construction tasks where portability and weight are concerns, the 6-1/2 inch or 5-1/2 inch models are more maneuverable. Always check if you require a complete kit with a battery or a tool-only version to complement your current workshop setup. By matching the RPM, blade diameter, and included accessories to your specific material demands, you can select a tool that provides the necessary precision and efficiency for your daily cutting tasks.
