Do you know that if the cordless circular saw has a long-lasting, powerful battery, it will surely be better than the corded circular saw? Well, this claim is entirely right, for the cord often gets in the way for comfortable working with the circular saw. Moreover, the cable adds weight to the tool and confines the circular saw in areas near an electrical outlet.
The cordless circular saw, in fairness, had improved a lot since its lithium-ion powered days when it was struggling to perform despite its 7-1/4-inch blade. At present, it now goes beyond the 15-amp corded models when it comes to performance, making it equal to or even better than its corded counterparts. This fact makes the cordless circular saw no longer a less appealing alternative for most woodworkers.

Buyer’s Guide: Factors to Consider When Buying a Battery-powered Cordless Circular Saw
Whether you are a hobbyist or a first-time buyer of a cordless circular saw, you need to be mindful of the succinct factors to consider when buying a cordless circular saw. Here are the key elements you need to consider when shopping around for the best cordless circular saw:
When purchasing a cordless circular saw, you will sometimes encounter 18V and 20V cordless circular saws. You may get confused with this difference and assume that the 20V ones are more powerful than the 18V ones. They are almost similar because when you fully charge the 18V circular saw, you will also get a 20V power for several minutes. The reason behind this is that the 18V has a 20V maximum power. So, you need not be confused with these two.
However, you will also come across the highest-power voltage 36V cordless circular saws, though they are not many. Of course, the 36V carries the most power among the given options, and if you are looking for the most powerful cordless circular saws, you should root out for this type of circular saws.
Rear-handle vs. Sidewinder
If you’re in the US, you will discover that this choice between sidewinder and rear-handle is more often associated with regions. If you are lodged on the West Coast, you will tend to favor the rear-handle, while if you’re residing on the East Coast, you will tend to go with the sidewinder. So, it’s more of a regional thing. Yet, there are subtle differences between the Sidewinder and Rear-Handle.
The rear-handle or worm drive saw, for example, still carries the original design of the first worm drive saw. Its motor sits behind its blade, which makes this tool narrow and long. This design is useful when framing a roof. Another thing is that the spiral gear or worm gear turns another gear at 90-degrees orientation. This other gear that turns the blade gives it a more enhanced torque. Hence, the worm drive saw is a powerful one and a good choice.
However, because the design of the worm drive saw has some limitations, engineers developed the sidewinder saw, or direct drive saw that features a motor adjacent to the blade. This design makes the saw broader and lighter while being shorter. If you are a tyro using a circular saw, you should use the sidewinder instead of the worm drive. Yet, your choice will still boil down to your preference.
The Blade on the Right or Left
If you are a pro woodworker, you will not make a fuss about whether the circular saw blade is situated on the left or right, for you will surely have a couple of cordless circular saws at hand. Yet, if you are new to woodworking, you can try both and figure out what is most convenient for you. If you are a right-hander, you may prefer a blade-left feature. Yet, it may not always be the case for most right-handers, for there are right-handed users who prefer the blade-right design.
If you are purchasing a circular saw, you might as well go for the one with a brushless motor. Of course, the brushless motor provides better runtime, performance, and even longer life. Brushless motors, as claimed by manufacturers, have better durability and performance. Moreover, the power tools with brushless motors are more power-efficiency compared to the other tools.
The brushless motor lets go of the old brushes and commutator. Its magnet locations, as well as the windings, are reversed. With this new setup, this tool can adjust accordingly to the task at hand. Hence, it is marketed as a smarter tool.
Another worth considering factor when buying a cordless circular saw is that of the electronic brake. This feature directs the blade to stop once you release the trigger quickly. Without this feature, the blade will rotate for 12 seconds after releasing the trigger, which could factor well when it comes to risk reduction.
It will help if you consider these other factors when buying a cordless circular saw like that of the rafter hook for hanging the saw, trigger safety design (push-in or push-down), dust port for better cleanup, rail compatibility for more accurate cut, LED light, cutline blower, and magnesium components. Check out for these additional factors if you genuinely want to zero in on the best cordless circular saw.
