However, you should count on using it for extended periods of time. While it’s comfortable to grip, it easily overheats, and its batteries drain pretty quickly.

Why Should You Use a Cordless Circular Saw?

The first thing that makes cordless circular saws great is how handy they are. All you have to do is charge them, and you’re free to use them for as long as the battery allows. 

You’re not limited to work in areas where a wall outlet is available.

You can carry them anywhere and work without having to fix them to supporting frames as they’re usually lightweight.

How to Pick a Circular Saw?

Before you pick a circular saw, there are a couple of things that you should take into consideration first.

Blade Size

How big your saw’s blade is will dictate the toughness of the materials you’ll be able to cut through. Naturally, the tougher your material is, the bigger your blade should be in order to be able to penetrate it.

Blade Adjustability

You’ll need to make frequent adjustments to your blade to fit the kind of cut you want to make. That’s why a saw with a blade that’s easy to adjust is always better.


Cordless saws are hand-held devices and are usually lightweight. The construction contributes to how heavy or light your device is, so look for lighter materials such as magnesium.

An ideal circular saw is light enough to maneuver yet strong enough to finish the job at hand.


You should look for a saw that will be able to withstand the kind of jobs you’ll do as well as last for the required duration. Its blade should also be durable and last as long as you provide it with good maintenance.


Your saw’s ability to cut through a certain kind of material doesn’t only depend on the size of the blade but also the power of the motor.

A small change in the amperage of voltage can go a long way. So the tougher the work you’ll do, the higher the numbers should be.

Ease of Use

Make sure your saw is easy to handle, control, and has a comfortable grip.

The ergonomics of the device will drastically affect the way you operate your tool.

Final Thoughts

The quest to find the best cordless circular saw isn’t an easy one, but the list above can help you narrow down the choices.

If you need even further narrowing down, then I’d recommend the DeWalt DC390B for its versatility, reasonable price level, and power.

On the other hand, the Black & Decker BDCCS20C is a great, more affordable alternative that provides you with portability and efficiency.

If you’re looking for the fastest or smoothest finishes on a lightweight model, then you should opt for the PORTER-CABLE PCC660B.

Finally, if being light is a concern of yours and you want a budget-friendly option, then I’d recommend the WORX WX429L.
