Overview of the Products
The DEWALT ATOMIC 20V MAX* Circular Saw is priced at $159.00, while the DEWALT FLEXVOLT 60V MAX* Circular Saw for Framing retails at $280.99. This means the FLEXVOLT model is about 77% more expensive than the ATOMIC model. Both products are designed for different applications and target audiences, making them suitable for various types of users. The ATOMIC model is ideal for those who need a compact, lightweight saw for smaller cuts, while the FLEXVOLT model is tailored for heavy-duty framing tasks.
Design and Build Quality
In terms of design, the DEWALT ATOMIC 20V MAX* Circular Saw features a compact and lightweight design, making it easy to handle for extended periods. It includes a removable auxiliary handle for improved control and has a hang hook for convenience. On the other hand, the DEWALT FLEXVOLT 60V MAX* Circular Saw for Framing boasts a robust magnesium shoe, which contributes to its durability and stability during use. This saw is designed with the blade oriented to the left of the motor, providing an optimal line of sight for cuts, a feature not highlighted for the ATOMIC model.
Cutting Capacity and Performance
The DEWALT ATOMIC model can cut up to 369 linear feet of 3/4-inch OSB using a compatible DCB205 battery, showcasing its efficiency in lighter applications. It features a bevel lever allowing cuts at 45 degrees for 1x dimensional lumber and can handle 2x material at 90 degrees. In contrast, the FLEXVOLT saw achieves a depth of cut of 2-7/16 inches at 90 degrees and has a bevel capacity of 53 degrees with stops at 45 degrees and 22.5 degrees, making it suitable for more demanding framing tasks. This difference in cutting capacity reveals that the FLEXVOLT saw is better suited for construction professionals needing precision and power for larger materials.
Motor and Speed
The DEWALT ATOMIC 20V MAX* Circular Saw is equipped with a brushless motor that allows for efficient cuts. While specific RPM figures are not disclosed, the focus on the brushless motor indicates reliability and longevity. In comparison, the FLEXVOLT 60V MAX* Circular Saw also utilizes a brushless motor, which is known for providing smooth and accurate cuts with extended runtime. This efficiency is crucial for professional contractors who often require a dependable tool for intensive work.
Safety Features
Safety is a significant concern for power tools, and both models come equipped with safety features. The DEWALT ATOMIC model includes an electronic blade brake that stops the blade quickly to enhance safety and productivity. This feature is particularly useful for users who frequently change cutting tasks. The FLEXVOLT model also features an electronic brake, which helps stop the blade after the trigger is released. Additionally, it has an integrated dust blower to maintain a clear line of sight, further enhancing safety during operation.
Portability and Convenience
The DEWALT ATOMIC 20V MAX* Circular Saw is designed for portability, given its compact size and lightweight nature, making it an excellent choice for those who need to move around frequently on job sites. Its hang hook and on-board blade key storage add to the convenience factor. Conversely, the FLEXVOLT saw, while slightly heavier, includes a rafter hook for easy access. Both tools offer onboard storage for blade wrenches, but the ATOMIC model's smaller size may make it easier to handle for casual users or DIYers.
Target Audience
The DEWALT ATOMIC 20V MAX* Circular Saw targets DIY enthusiasts and professionals who require a lightweight, compact saw for smaller tasks. Its features cater to users who may not need the power of a larger saw. In contrast, the DEWALT FLEXVOLT 60V MAX* Circular Saw for Framing is designed for professional contractors, carpenters, and framers who often work with larger materials and require a reliable, high-performance saw for demanding applications.
Which should you buy?
The choice between the DEWALT ATOMIC 20V MAX* Circular Saw and the DEWALT FLEXVOLT 60V MAX* Circular Saw should be based on your specific needs and budget. If you are looking for a lightweight, affordable tool for smaller cuts and projects, the ATOMIC model, priced at $159.00, is an excellent option.
