DEWALT 20V MAX Circular Saw, 6-1/2-Inch (DCS391B)
The DCS391B is a compact, cordless option built around 20V MAX power. Its 5150 RPM motor and 460 MWO deliver solid performance for everyday framing and trim work. A lightweight magnesium shoe reduces fatigue while maintaining rigidity for precise cuts, and the rubber overmolded grip provides comfortable control during extended use. The model features a 6-1/2-inch blade and a bevel range up to 50 degrees, making it versatile for typical carpentry tasks. Battery not included means you can pair it with your existing 20V MAX pack for a balanced mix of weight and runtime.
Durability and balance are enhanced by DeWalt’s trademark built-in features: a robust base plate, reinforced arbor, and reliable braking when needed. This model is best suited for professionals who value a compact footprint without sacrificing performance on common 2×4 framing and finish work. It is also compatible with a wide array of DeWalt blades, allowing quick swaps between plywood, hardwood, and softwood as jobsite demands rise.
DEWALT 20V MAX* XR Brushless Circular Saw, 7-1/4 in. (DCS590B)
The DCS590B represents a high-performance 20V MAX cordless option with a brushless motor designed to maximize runtime and speed. It delivers up to 5,500 no-load RPM and as much as 1,700 MWO, enabling fast, aggressive cuts through challenging materials. The 7-1/4-inch blade is paired with a maximum depth of cut of 2-9/16 inches at 90 degrees and 2 inches at 45 degrees, giving you the flexibility to tackle framing, sheathing, and cross-cuts in one session. This model is ideal when you need robust power without dragging a cord, especially on longer runs or in space-restricted areas.
As a cordless workhorse, the DCS590B emphasizes versatility and efficiency. With a brushless design, it maintains torque and heat management across repeated heavy cuts. The tool is sold as a bare unit (battery not included), so it integrates smoothly with an existing 20V MAX line or can be paired with new packs for extended runtime. Ergonomics are designed for balance, allowing users to guide the cut with confidence through dense or layered materials.
DEWALT ATOMIC 20V MAX Circular Saw, 4-1/2-Inch (DCS571B)
The DCS571B is part of DeWalt’s Atomic line, designed for compact power and easy handling. This 4-1/2-inch cordless saw uses a brushless motor to optimize efficiency and runtime for smaller rum tasks and quick site work. The tool’s smaller size makes it ideal for overhead or tight-space cuts where a full-size saw would be cumbersome. A removable auxiliary handle adds control when starting and maintaining course accuracy, while a hang hook provides simple storage between tasks. For budget-conscious users who still want DeWalt reliability, this model offers an efficient balance of size, weight, and performance.
Battery compatibility is straightforward: the DCS571B can use the DCB205 battery (sold separately), enabling a quick upgrade path for users already invested in the 20V MAX ecosystem. Its compact footprint does not significantly compromise capability, making it a practical choice for trim work, cabinetry, and smaller framing jobs where a lighter tool is advantageous.
DEWALT FLEXVOLT 60V MAX Circular Saw With Brake, 7-1/4-Inch (DCS578B)
The DCS578B is a FLEXVOLT 60V MAX circular saw designed for heavier-duty workloads. DEWALT highlights up to 47% more power versus the older DCS575 model, making it a strong choice for larger framing or rough-cut tasks that demand sustained torque. The 7-1/4-inch blade provides the standard large-cut capability, and the saw offers a maximum depth of cut of 2-9/16 inches at 90 degrees. Bevel capacity goes up to 57 degrees, with stops at 22.5 and 45 degrees, enabling intricate angle cuts on complex projects. A built-in brake enhances safety by stopping the blade quickly after the trigger is released. Battery not included, aligning with many users’ existing FLEXVOLT setups.
Ergonomically designed for balance under load, the DCS578B combines robust construction with practical features such as a snug grip, efficient dust management, and compatibility with standard blades. It is well-suited for pros who move between large and small projects and require a single tool that can handle a wide range of materials while maintaining consistent accuracy and speed.
DEWALT Cordless Circular Saw (Bare Tool) (Renewed)
The Renewed DEWALT cordless circular saw provides a value option with reconditioned confidence. It uses a robust 460 MWO motor and delivers around 5,150 RPM, which supports a broad range of cutting tasks with respectable speed and power. A magnesium shoe is included to maintain durability without excessive weight, and the design retains the core features customers expect in DeWalt tools, such as stable tracking and reliable cutting performance. The Renewed unit is an economical choice for budget-minded buyers who still want the performance and compatibility of DeWalt components.
As a renewed tool, it typically ships with basic components suitable for common carpentry needs. Weight balance and ergonomics are consistent with DeWalt’s other circular saws, enabling comfortable handling for long sessions. Battery compatibility follows the standard 20V MAX ecosystem, so you can pair it with your existing packs or purchase a new one for extended work sessions.
Buying Guide
Key purchase considerations help you choose the right DeWalt cordless circular saw, balancing power, size, and runtime for your typical projects.
- Power and motor type: Brushless motors deliver greater efficiency and longer life, especially under heavy use. If you frequently cut thick materials, consider the FLEXVOLT 60V options for sustained torque across longer sessions.
- Blade size and cut depth: A 6-1/2″ blade is compact for trim tasks, while a 7-1/4″ blade handles framing and larger boards. Always verify the maximum depth of cut at 90° and 45° to ensure the tool meets your material requirements.
- Bevel capacity: Higher bevel ranges (up to 57°) provide more angle-cut flexibility for complex joints. Stops at common angles (22.5°, 45°) help repeat precise cuts.
- Battery ecosystem: 20V MAX models integrate easily with existing smaller batteries, while FLEXVOLT models use higher-capacity packs for extended runtime. Battery-not-included configurations are common; plan your purchase around the packs you already own or plan to acquire.
- Ergonomics and durability: Magnesium shoes reduce weight while maintaining rigidity, and rubber overmold handles improve grip. A baselined brake feature enhances safety by stopping the blade quickly after cutting is stopped.
- Accessories and blades: Ensure compatibility with standard 7-1/4″ or 6-1/2″ blades, and consider additional blades for different materials (plywood, hardwood, OSB, and metal cutting).
- Budget and use-case: Cordless designs offer portability and ease of use on job sites, but heavier 60V tools may be preferable for frequent, high-volume framing. A compact 4-1/2″ model is ideal for tight spaces and lighter trim work.
