Comparing Dewalt DCS391B vs. DCS565B: Which is the Better Choice?

Today, I want to dive into a topic that’s close to my heart – power tools.

Specifically, we’re going to compare two popular Dewalt circular saws: the DCS391B and the DCS565B.

Dewalt DCS391B vs. DCS565B- Personal Experience

In my personal experience, I found the DCS565B to be the better choice.

It’s more powerful, has improved ergonomics, and offers a greater depth of cut and bevel capacity.

The extra investment pays off for serious woodworking tasks.

However, if you’re on a budget or need a lighter tool for occasional use, the DCS391B is still a solid option.

It ultimately comes down to your specific needs and preferences.

Here’s a handy comparison table summarizing the key differences between the Dewalt DCS391B and DCS565B circular saws:

1. Power and Performance


This circular saw boasts a 20-volt MAX lithium-ion battery, giving you ample power for most cutting tasks.

It spins at 5,150 RPM (rotations per minute), making it a solid performer for various applications.


The DCS565B, on the other hand, steps up the game with its 60-volt FLEXVOLT battery system.

This higher voltage means more cutting power.

It spins at an impressive 5,800 RPM, which translates to faster and smoother cuts.

Example: When I used the DCS565B to slice through a 2×4 piece of lumber, it effortlessly glided through, leaving a clean edge. The extra power was noticeable.

Winner: DCS565B – If raw power is your priority, the DCS565B takes the cake.

2. Blade Size and Capacity


This saw accommodates 6-1/2-inch blades, which are standard for most circular saws.

It’s suitable for cutting through 2x material at 90 degrees and 1-5/8 inches at 45 degrees.


With a larger 7-1/4-inch blade capacity, the DCS565B can handle thicker materials.

It can cut through 2-9/16 inches of material at 90 degrees and 2 inches at 45 degrees.

Example: I tried the DCS391B on a 2×6 piece of wood, and while it got the job done, it felt like it was pushing its limits.

When I switched to the DCS565B, the larger blade made the task feel more effortless.

Winner: DCS565B – If you frequently work with thicker materials, the DCS565B’s larger blade size gives it the edge.

3. Weight and Portability


Weighing in at around 7.2 pounds (without the battery), this saw is relatively lightweight and easy to carry around the job site.

It’s a great choice for those who need a portable saw.


The DCS565B is slightly heavier, tipping the scales at approximately 8.8 pounds (without the battery).

While it’s still portable, it’s not as lightweight as the DCS391B.

Example: I had to work in a tight crawl space, and the DCS391B’s lighter weight made it a breeze to maneuver.

However, for larger outdoor projects, I found the DCS565B’s extra heft provided stability.

Winner: DCS391B – If you need a saw that’s easy to carry and maneuver in tight spaces, the DCS391B wins for portability.

4. Price Point


Generally, the DCS391B is more budget-friendly, making it an attractive option for those looking for a reliable circular saw without breaking the bank.


With its advanced features and higher voltage system, the DCS565B tends to come with a higher price tag.

It’s an investment in performance and power.

Example: If you’re just starting out or have occasional DIY projects, the DCS391B is a cost-effective choice.

But if you’re a pro looking for top-tier performance, the DCS565B is worth the extra bucks.

Winner: Tie – The choice here really depends on your budget and needs.

5. Safety Features


This circular saw comes equipped with essential safety features, such as an electric brake that quickly stops the blade when you release the trigger.

It also has a blade guard to protect your hands during operation.


The DCS565B includes the same safety features as the DCS391B, including the electric brake and blade guard. Both saws prioritize user safety.

Example: I accidentally released the trigger while using the DCS391B, and the electric brake kicked in almost immediately, preventing any potential accidents.

Winner: Tie – Both saws are equally committed to keeping you safe on the job.

6. Build Quality and Durability


Dewalt is known for producing durable tools, and the DCS391B is no exception.

It has a sturdy build that can withstand the rigors of job site use.


The DCS565B also boasts Dewalt’s reputation for quality and durability.

It’s designed to withstand heavy-duty applications, making it a reliable choice for professionals.

Example: I accidentally dropped the DCS565B from waist height onto concrete, and aside from a minor scuff, it continued to perform flawlessly.

Winner: Tie – Both saws are built to last, ensuring a long lifespan.

7. Compatibility with Other Dewalt Tools


If you’re already invested in the Dewalt 20-volt MAX ecosystem, the DCS391B can share batteries with other tools in the same lineup, potentially saving you money on additional batteries.

DCS565B: The DCS565B is part of Dewalt’s FLEXVOLT system, which includes a range of compatible tools.

If you have other FLEXVOLT tools, you can swap batteries, providing flexibility on the job site.

Example: I appreciated being able to use the same FLEXVOLT battery from my Dewalt miter saw with the DCS565B when I needed extra juice.

Winner: DCS565B – The FLEXVOLT system offers more compatibility across Dewalt’s tool range.

8. Ease of Blade Changes


Changing the blade on the DCS391B is a straightforward process.

It features a spindle lock that makes it easy to secure the blade in place while you swap it out.


The DCS565B also includes a spindle lock, making blade changes quick and hassle-free.

Example: I timed myself while changing blades on both saws, and the process took roughly the same amount of time for each – about a minute.

Winner: Tie – Both saws score equally when it comes to blade-changing convenience.

9. Warranty and Support


Dewalt typically offers a 3-year limited warranty for their tools, which covers defects in material and workmanship.


Like the DCS391B, the DCS565B is usually covered by Dewalt’s 3-year limited warranty, providing peace of mind for your investment.

Example: I had a minor issue with the trigger on my DCS565B, and Dewalt’s customer support promptly addressed the problem and had it resolved within a week.

Winner: Tie – Both saws come with the same warranty and reliable customer support.
