- Easy to use with intuitive controls and clear markings on the shoe
- Great value for the performance, as noted by many users

The DEWALT 20V MAX XR Brushless Cordless 7-1/4 in. Circular Saw (DCS590B) is a high-performance tool designed for professionals and serious DIYers who need reliable cutting power on the go. As the most powerful 20V MAX circular saw from DEWALT, it delivers up to 1,700 MWO, making it suitable for tough applications like framing, decking, and plywood cutting.
Standout features include a brushless motor that achieves up to 5,500 RPM and provides up to 368 cuts per charge, significantly reducing downtime. The electric brake stops the blade instantly when the trigger is released, enhancing safety and cutting accuracy. Users praise its smooth cuts and ample power, with many noting it handles 1/2-inch plywood and dimensional lumber effortlessly.
Design-wise, the saw is built with durability in mind. It has a right-blade orientation for better cut-line visibility and a top handle for comfortable control. The bevel capacity of 57 degrees with stops at 45 and 22.5 degrees adds versatility. However, at 9.9 pounds, it is on the heavier side, and the plastic handle may not feel as robust as metal options.
One drawback is that this is a tool-only purchase, meaning you need a DEWALT 20V MAX battery and charger (sold separately). This can increase the upfront cost if you are not already invested in the platform. Additionally, some users may prefer a lighter saw for overhead or prolonged use.
Overall, the DEWALT DCS590B offers exceptional power, runtime, and safety features at a competitive price. It is an excellent investment for those who need a cordless circular saw that can match corded performance. For homeowners and contractors alike, this saw delivers reliable, accurate cuts and is highly recommended.
Pros
- Lightweight and well-balanced, easy to handle for extended periods.
- Smooth and powerful motor, comparable to corded saws in performance.
- Wide bevel range (0-50°) for versatile cutting angles.
- Keyless blade change simplifies blade swaps on the job.
- Durable magnesium shoe adds stability and accuracy.
Cons
- Battery and charger are sold separately, adding to initial cost.
- Motor and blade guard can obstruct the cut line, making visibility challenging.
- Depth adjustment lever may bind or stick during use, requiring extra effort to adjust.
The DEWALT DCS391B is a 20V MAX cordless circular saw designed for professionals and serious DIYers who demand portability without compromising cutting power. Its 6-1/2 inch blade and 5150 RPM motor make it a capable tool for framing, roofing, and breaking down sheet goods.
In real-world use, the saw impresses with its smooth, powerful motor that handles pressure-treated lumber and plywood with ease. The lightweight magnesium shoe keeps the saw stable and accurate, while the 0-50 degree bevel capacity allows for versatile cutting angles. Users report that with a quality 5Ah battery, the saw performs like a corded model, offering ample runtime for most jobs.
Design and build quality are typical DEWALT: robust construction with a comfortable rubber over-molded grip. The keyless blade change system is a time-saver, and the spindle lock adds safety. However, the saw's weight of about 7 pounds with a battery makes it easy to maneuver for extended periods.
Potential drawbacks include the line of sight being partially blocked by the motor and blade guard, which can make following a cut line tricky. The depth adjustment lever may also be stiff at first. Additionally, the battery and charger are sold separately, so factor that into your purchase.
Overall, the DEWALT DCS391B is a stellar cordless saw that delivers professional-grade cuts in a portable package. It's a worthy investment for anyone already invested in the DEWALT 20V MAX system or looking for a reliable, lightweight circular saw.

Buying Guide: What to Look for in a Circular Saw
Power and Motor Technology
The heart of any circular saw is its motor. Brushless motors, like the one in the DEWALT 20V MAX XR, deliver higher efficiency, longer runtime, and more torque than brushed alternatives. This translates to smoother cuts through pressure-treated lumber and dense hardwoods. For most framing and remodeling tasks, you want at least 4,000 RPM. The XR model pushes that to 5,500 RPM, giving you the speed to cut with confidence.
Blade Size and Cut Depth
Blade diameter directly affects what you can cut. A 7‑1/4‑inch blade (like on the DEWALT 20V MAX XR) offers a maximum depth of cut around 2‑9/16 inches at 90°, which is ideal for cutting through 2x lumber in one pass. The 6‑1/2‑inch blade on the DEWALT 20V MAX Circular Saw is lighter and still handles 2x material at a shallower depth. For versatility, consider the tasks you tackle most: larger blades suit heavy framing, while smaller blades excel in tight spaces and overhead work.
Battery System and Runtime
Cordless saws rely on battery compatibility. DEWALT’s 20V MAX platform is shared across dozens of tools, so investing in extra batteries pays off. The XR model boasts up to 368 cuts per charge, making it a workhorse for long sessions. The standard 20V MAX saw is more modest but still sufficient for intermittent use. If you already own DEWALT batteries, either saw is a smart addition. For more insights on battery performance, see our best cordless circular saw recommendations.
Weight and Ergonomics
A saw that’s heavy or poorly balanced leads to fatigue and inaccurate cuts. The DEWALT 20V MAX Circular Saw weighs roughly 7.5 pounds (without battery) thanks to a magnesium shoe, while the XR model is slightly more robust but still manageable. Both feature overmolded grips that reduce vibration. If you’ll be cutting all day or working overhead, prioritize a lighter tool. Our guide to lightweight circular saws can help you compare further.
Final Thoughts
After thorough evaluation, we believe the DEWALT 20V MAX XR Brushless Cordless 7-1/4 in. is your best bet for heavy-duty jobs that demand extra power and longer runtime, while the DEWALT 20V MAX Circular Saw excels as a nimble, budget-friendly companion for everyday cuts. Both deliver the reliability DEWALT is known for, so your choice comes down to the balance of power and portability your projects require. Whichever you pick, you’re getting a tool that’s been validated to perform on real job sites.

Frequently Asked Questions
What size circular saw blade should I use for general cutting?
A 7‑1/4‑inch blade is the most versatile for framing and sheet goods, as it can cut through 2x lumber in a single pass. A 6‑1/2‑inch blade is lighter and works well for plywood and thinner materials, especially if you need to make bevel cuts.
Are cordless circular saws powerful enough for framing?
Yes, modern cordless circular saws like the DEWALT 20V MAX XR are more than capable of framing. With brushless motors delivering over 5,000 RPM and high-capacity batteries, they can handle pressure-treated lumber and engineered wood with ease. Many pros have switched to cordless for convenience without sacrificing power.
How long do circular saw batteries last on a single charge?
Runtime depends on battery amp-hours and the saw’s motor efficiency. The DEWALT 20V MAX XR can achieve up to 368 cuts per charge with a 5Ah battery, while the standard 20V MAX saw offers fewer cuts. For all-day use, consider keeping a second battery on hand. You can also check our compact circular saw guide for more runtime insights.
Can I use a circular saw for cutting metal?
Yes, with the right blade. Circular saws can cut metal, including rebar, sheet metal, and aluminum, but you need an abrasive or carbide-tipped blade designed for metal. Always reduce speed if possible and wear proper safety gear. Note that cutting metal will wear blades faster and produce sparks.
