Cordless Circular Saws Buyer’s Guide
Although we’ve given you the best cordless circular saw reviews, we’re not done yet. Here is a list of the factors you need to consider when looking for your own saw.
Battery and Power
On average, most cordless circular saws can offer at least 3500 RPM. Better versions offer 4000 to 4800, and if you want a high-end cordless circular saw, you can find some with over 5000 RPM. Though higher RPMs represent better cutting performance, they’re not a good indicator of torque. However, some models like the Worm Drive offer high torque as a feature.
The “V” in 18V, 36V, or 48V stands for “Voltage”. Voltage is the unit of measurement for power in a battery. Most cordless circular saws use a Lithium-ion (Li-ion) battery. These batteries are preferred because they’re fast-charging, lighter, and don’t have a memory effect. Several cordless circular saws use 18-volt or 20-volt Li-ion batteries, which normally provide enough power for a 2-inch cut.
Ampere-hour (Ah) is used to measure how long the battery can last before it needs to recharge. This usually ranges between 3 to 5 Ah. Some cordless circular saws use nickel-cadmium (Ni-cd) batteries, but these lose efficiency as they continue to discharge.
Brushed or Brushless Motor?
You may not have come across the latter if you were using corded circular saws. The reason for this is that this term doesn’t really matter to motors with an unlimited supply of power.
The difference between brushed and brushless motors has to do with the relationship between friction, energy, and efficiency. What you need to know is that brushless motors produce less friction. Because less friction is produced, they’re able to use energy more efficiently. They usually get efficiency ratings between 85 percent and 90 percent. Brushed motors average around 75 to 80 percent because a lot of energy is lost to the continuous friction between parts.
In a cordless circular saw, power is generated by a battery. This is a very limited supply, and that extra 10 percent of wasted energy can be the difference between completing your work or the saw petering out before you’re done.
Another advantage of brushless motors is the reduced production of heat. All machines produce heat, but since friction is reduced in these models, heat is also diminished.
Higher energy efficiency also means your battery can allot more power to spinning the blade, thereby producing a higher RPM and more torque. Most powerful cordless circular saws use brushless motors, from 7-1/4-inch ones like the DeWalt DCS391B to smaller ones like the Black+Decker Max 5-1/2-inch saw.
Blade & Cutting Capacity
The larger the blade size, the more power is needed to rotate it. Because cordless circular saws have a limited supply of power, most cannot handle large blades. The longest is 7-1/4, which is fairly rare and needs a strong motor to generate sufficient rotations/minute to make cuts.
Smaller blades produce more torque and can generate higher RPMs because they don’t need a lot of power to turn, but they’re limited in cutting depth. A lot of cordless circular saws have 6-1/2-inch blades, which are a good mid-point. There are even 5-1/2 and 4-1/2-inch blades.
Some brands have cordless saws with small blades and a longer 7-1/4-inch blade as their high-end version.

Most cordless circular saws have handles on the left-side to provide a clear view of the machine and material during use.
The best cordless circular saw should have an ergonomic handle shaped to enhance grip. You’ll need a firm grip to push the saw into the material to create a clean cut.
There is also the handle position. The most common are the rear handles and sidewinder. Rear handle saws stay at the back of the machine. Rear saws are usually on the heavier side. Sidewinder handles are located right beside the blade. The saws are smaller and lighter and can easily cut materials from that angle.
Ease of Use
How user-friendly a saw is depends on several features like handle position, blade position, power, cutting depth, maneuverability, and adjustability. If a saw is powerful, light, and also has features that allow it to be easily adjusted for greater accuracy, it will be easy to use.
Thousands of worksite accidents happen every year. To reduce the chances of a workplace injury, you should include safety features as a non-negotiable criterion in your search for your best cordless circular saw.
Some safety features common in circular saws include blade locks that automatically stop the blade when the user releases the trigger switch. There are also blade guards that are retractable, molded, rubber handles that prevent the machine from slipping out of your grip, and trigger safeties that guard against accidental starts.
Sawdust is carcinogenic , so a dust collection device or dust port is extremely important when you’re working with wood pieces. Some saws come with this feature, but you may have to purchase a dust port separately, especially for those that saws that come as bare tools.
Other Additional Features
Depending on the cordless circular saw and manufacturer, many saws have extra features that make them more impressive. Some have technology designed to prevent overheating, overloading, and over-discharging, and prolong the saw’s use.
There is also technology that protects these cordless circular saws from water & dust and provides bevel adjustments or torque & speed adjustments based on the material.

Are battery-powered circular saws any good?
Yes, battery-powered circular saws work great, especially on job sites where it’s too busy to drag a cord all over the place. Many cordless saws can now compete in power with corded ones especially ones specifically made for power like the DeWalt FlexVolt 60V Max Circular Saw. Even smaller sidewinder models like the Black+Decker 5-1/2-inch pack a fair punch.
Are cordless circular saws worth it?
