1. Power and Performance

DCS565: This cordless circular saw is part of Dewalt’s 20V MAX lineup, offering a respectable 4600 RPM. It’s known for its efficiency and can handle various cutting tasks.

DCS391: The DCS391 is a cordless circular saw powered by an 18V battery, delivering 5150 RPM. It’s no slouch when it comes to cutting speed.

Example: If you need to make quick, precise cuts through hardwood, the DCS565’s slightly lower RPM might cause a slight delay compared to the DCS391. However, for general woodworking tasks, both will perform admirably.

2. Battery Compatibility

DCS565: This model is compatible with Dewalt’s 20V MAX lithium-ion batteries, which are quite common and can be found in many other Dewalt tools.

DCS391: The DCS391 uses Dewalt’s 18V batteries, which are a bit older and may not be as readily available.

Example: If you already own Dewalt 20V MAX batteries from other tools, the DCS565 is a more convenient choice, saving you from investing in a new battery platform.

3. Weight and Portability

DCS565: Weighing in at around 7 pounds, the DCS565 is lightweight and easy to maneuver, making it an excellent choice for overhead cuts and prolonged use.

DCS391: The DCS391 is a bit heavier, tipping the scales at approximately 9 pounds. While it’s still manageable, extended use might be more tiring.

Example: If you’re planning a project that involves a lot of overhead work, the DCS565’s lighter build could be a game-changer for your comfort and productivity.

4. Additional Features

DCS565: This circular saw boasts a brushless motor, which increases efficiency and extends tool life. It also has an electric brake for improved safety.

DCS391: While it lacks a brushless motor, the DCS391 has a magnesium shoe for added durability and strength.

Example: If you’re a professional who relies on your tools daily, the DCS565’s brushless motor and electric brake may be worth the investment. For occasional use, the DCS391’s magnesium shoe should suffice.

5. Price Point

DCS565: Generally, the DCS565 is priced slightly higher than the DCS391 due to its newer features and compatibility with 20V MAX batteries.

DCS391: Being an older model, the DCS391 often comes with a more budget-friendly price tag.

Example: Your budget plays a crucial role in your decision. If you’re looking for a more cost-effective option and don’t mind the older battery platform, the DCS391 could be the way to go.

6. Depth of Cut

DCS565: This saw offers a maximum depth of cut of 1-9/16 inches at a 90-degree angle and 1-3/8 inches at 45 degrees.

DCS391: The DCS391 provides a slightly deeper cut at 2-1/4 inches at 90 degrees and 1-5/8 inches at 45 degrees.

Example: If your projects require cutting thicker materials, the DCS391 offers a significant advantage with its greater cutting depth.

7. Bevel Capacity

DCS565: It has a bevel capacity of up to 50 degrees, allowing for versatile angled cuts.

DCS391: The DCS391 offers a bevel capacity of up to 50 degrees as well, ensuring you can make beveled cuts with ease.

Example: Both saws have identical bevel capacities, so it’s a tie in this department.

8. Dust Management

DCS565: This circular saw comes with a dust blower to keep your cutting line clean, providing better visibility.

DCS391: The DCS391 doesn’t feature a built-in dust blower, which might lead to reduced visibility during cuts.

Example: If you work in dusty environments or prioritize visibility during cuts, the DCS565’s dust blower is a handy feature to have.

9. Ergonomics and Grip

DCS565: It features an ergonomic handle with a rubber over-mold, offering a comfortable and secure grip.

DCS391: The DCS391 also comes with an ergonomic handle design, ensuring a comfortable grip during extended use.

Example: Both saws are designed with user comfort in mind, providing excellent ergonomics for prolonged cutting tasks.

10. Availability and Future-Proofing

DCS565: Being a newer model, the DCS565 is more readily available in stores and online. This means you’re more likely to find replacement parts and accessories in the future.

DCS391: The DCS391 might become less available over time as Dewalt focuses on promoting newer models.

Example: If long-term availability and future-proofing your investment are priorities, the DCS565 has the upper hand due to its newer status.

11. Blade Size

DCS565: This saw uses a 6-1/2-inch blade, which is common for many cordless circular saws and offers a good balance of cutting capacity and portability.

DCS391: The DCS391 utilizes a larger 7-1/4-inch blade, which provides a slightly deeper cut and is the standard size for most circular saws.

Example: If you frequently need to make deeper cuts, the DCS391’s larger blade size might be advantageous. However, if you prefer a lighter and more compact tool, the DCS565’s 6-1/2-inch blade could be your choice.

12. Shoe Material

DCS565: It features an aluminum shoe, which is durable and helps maintain the saw’s lightweight design.

DCS391: The DCS391’s shoe is made of magnesium, known for its strength and resistance to corrosion.

Example: If you prioritize durability and are willing to handle a slightly heavier tool, the DCS391’s magnesium shoe is an excellent feature.

13. Cutting Capacity at 45 Degrees

DCS565: This saw has a 45-degree bevel capacity and can cut up to 1-1/8 inches deep at that angle.

DCS391: The DCS391 also has a 45-degree bevel capacity but offers a deeper cut of up to 1-5/8 inches.

Example: If you frequently make beveled cuts at a 45-degree angle, the DCS391’s greater cutting capacity could be a deciding factor.

14. Additional Safety Features

DCS565: Apart from the electric brake mentioned earlier, it also has an integrated LED light that illuminates the work area for enhanced visibility.

DCS391: The DCS391 lacks an electric brake and LED light, which might be missed in low-light conditions.
