You are building a custom bookshelf, and you need to rip through a 3/4-inch plywood sheet with clean, straight cuts. A cheap handsaw will not cut it, and a table saw might be overkill.

Whether you are a seasoned woodworker or a weekend DIYer, this review will help you decide if this cordless tool fits your shop. If you are just starting out with power saws, check our guide on the best circular saw for beginners for more foundational tips.
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.

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 for the Best Circular Saw for Woodworking
Choosing the right circular saw for woodworking goes beyond just picking a familiar brand. You need to consider several factors that directly affect cut quality, convenience, and safety. Below we break down the key criteria we used to evaluate the DEWALT 20V MAX Circular Saw.
Motor Power and Speed
A powerful motor ensures you can cut through hardwoods and dense plywood without bogging down. The DEWALT 20V MAX delivers 5,150 RPM, which is more than enough for most woodworking tasks. This speed, combined with a 6-1/2-inch blade, allows for fast, clean cuts even in thicker stock. For a broader look at what to expect from cordless saws, our best circular saw for DIY article covers similar performance metrics.
Blade Size and Cut Depth
Blade diameter determines the maximum depth of cut. A 6-1/2-inch blade like the one on this DEWALT model can cut up to 2-1/8 inches at 90 degrees and 1-5/8 inches at 45 degrees. That is enough to handle 2×4 lumber and most sheet goods. Larger blades offer deeper cuts but add weight; the 6-1/2-inch size strikes a great balance for woodworking portability.
Bevel Capacity and Adjustment
Bevel cuts are common in woodworking for angled joints and chamfers. The DEWALT saw offers a 0 to 50 degree bevel range, which is more than the typical 45 degrees. This extra range gives you flexibility for compound cuts. The bevel adjustment is tool-free, making on-site changes quick and easy. If you often work with angled cuts, this feature alone makes the saw a strong contender.
Ergonomics and Portability
A circular saw that is too heavy or poorly balanced will fatigue your arms and reduce accuracy. The DEWALT 20V MAX features a magnesium shoe that is both lightweight and durable. The rubber over-molded grip provides comfort and control. At just over 7 pounds with a battery, it is easy to maneuver on a job site or in a home workshop.

After evaluating the DEWALT 20V MAX Circular Saw against our key criteria, we confidently recommend it as the best circular saw for woodworking in 2026. Its 5,150 RPM motor, 0-50 degree bevel capacity, and lightweight magnesium construction make it a versatile tool for everything from ripping plywood to cutting angled joints. Whether you are a professional carpenter or a hobbyist, this saw delivers the precision and power you need without the cord. DEWALT 20V MAX Circular Saw is the only model we reviewed, and it stands out as a top performer for woodworking applications.
