DeWalt DCS577B 60V MAX Circular Saw for Framing

A lightweight circular saw that’s ideal for repetitive jobs with its electronic brake and brushless motor.


As a cordless worm drive circular saw, this unit works well for most jobs that require flexibility and portability, such as outdoor projects and working in difficult positions. It will also work well as a supplemental or backup drive saw to your main unit.


For the specs, the DCS577B is a 7-1/4-inch worm drive saw with a 53-degree bevel capacity, and stops at 22.5 and 45 degrees. When it comes to its cutting capacity, it can handle up to 2-7/16 inches of material at 90 degrees.

When it comes to speed, it runs up to 5,800 RPM, so it’s suitable for difficult tasks where time is important. Without the battery, the tool weighs 10.87 pounds.


As with most DeWalt products, it comes with a 3-year limited warranty, as well as a 90-day money-back guarantee and 1 year of free service.

With that said, the manufacturer made this circular saw durable with quality parts, so it’s likely that you won’t even have to worry about the warranty period. For instance, it has an electric brake that stops the blade almost instantaneously, to quickly replace the blade while avoiding unnecessary strain on the motor.

When it comes to power, it runs on a more efficient brushless motor (direct drive). Compared to regular motors that use carbon brushes, this one doesn’t require a lot of maintenance and runs significantly cooler, so you can use it for the tough jobs.

Since it comes with a dust blower, it will also protect the motor from jamming or overheating due to work debris. The durability of the construction is also good thanks to its high-grade magnesium shoe. Also, like most cordless units today, it uses lithium-ion for its battery so it holds a charge longer than traditional batteries.


In terms of usability, this worm drive circular saw has a dust blower that not only protects the motor from getting damaged due to sawdust, but it also clears the line of sight. This will be important for maintaining accurate and consistent cuts.

Moreover, its electric brake will help you change the blade with speed and ease. Unlike other units that do not have this feature, the blade stops quickly, which means better safety for the user.

Aside from that, it has a rafter hook so you can hang the tool onto your shed or garage wall when it’s not in use. Additionally, when changing blades, you won’t risk losing your wrench since it has onboard storage for that too.

Furthermore, this worm drive saw has compatibility with any Tool Connect Tag (if you have such) due to its pre-drilled holes.

Should You Buy the DeWalt DCS577B Worm Drive Circular Saw?

I think that the DeWalt DCS577B fits your needs if you’re looking for a circular saw that’s portable yet packs a lot of power and speed. The convenient features, such as the electric brake, dust blower, onboard wrench storage, and rafter hook will help you out on your project – whether it’s a DIY task at home or out on a jobsite.

If you are still unsure about your decision, go through the below list of the pros and cons of the tool.

Pros of the DeWalt DCS577B

Let’s start with the pros.

It has a high no-load speed.

With up to 5,800 RPM of speed, this worm drive saw has one of the highest no-load speeds in its class. This makes it easier for you to finish jobs, especially if you need to cut longer materials.

It has an electric brake.

With an electric brake to instantly stop the blade from spinning, it will put your mind at ease when it comes to safety concerns. It also speeds up the process of switching from one blade to another.

It comes with an integrated dust blower.

Dust management is very important in woodworking. By using this onboard dust blower, you’ll not only clear your surroundings from dust, but it will also let you see the line of sight better, which results in better accuracy.

It has a brushless motor.

A brushless motor runs cooler than a motor that uses traditional carbon brushes. This helps the motor last longer, especially when you’re working in the summer.

Cons of the Product

Even though the DeWalt DCS577B is a great tool, there are a few cons worth noting as well.

The front shoe nut lacks stability.

I think that the front shoe nut needs a little tweaking in terms of stability. Regardless, the worm drive saw is still usable and workable and this stability problem won’t be easily noticed by casual users.

It doesn’t have a work light.

Although we would’ve liked to see an LED work, as seen in some worm drive saws for better accuracy, not all woodworkers need it, especially if you will work outside.

What Are the Alternatives to the DeWalt DCS577B?

Alternative to DeWalt DCS577 Although the DeWalt DCS577B is a worthy choice for a worm drive saw, if you simply don’t find it suitable for your needs, here are other similar alternatives:

When it comes to cordless power, a similar tool to consider is the Milwaukee 2830-20 Circular Saw with Rear Handle. Like my main pick (the DCS577B), it has a high speed of up to 5,800 RPM and it runs on a brushless motor. Moreover, it has a rafter hook for easy storage. However, this saw has an LED work light that makes it unique among most units out there.

The Milwaukee 6477-20 7-1/4-Inch Worm Drive Circular Saw is another similar saw to consider when it comes to length and it also has a similar depth of cut at 2-7/16 inches at 90 degrees. What’s more, it also has a similar magnesium construction. While this unit doesn’t have an electric brake, it still has a spindle lock, which also speeds up blade change as a whole, with a reduced chance of injuries.

If you are looking for a circular saw with a similar high speed, the Bosch CSW41 7-1/4-Inch Worm Drive Circular Saw is for you, which has up to 5,300 RPM of no-load speed. It also has a similar onboard wrench that makes blade changes a breeze. Also, it has a soft-grip handle and a lowered guard with a design that works well for small workpieces.

Overall, the DeWalt DCS577B is a worthy tool to get if you’re after a worm drive circular saw that runs cool, has a high speed, good dust management, and provides ease of changing the blades. Although it lacks a work light and a few little tweaks, it is a great cordless saw to use for most DIY and jobsite woodworking tasks.
