Cordless Circular Saw Buying Guide
The portability of cordless circular saws is a great advantage. Thanks to battery technology improvement, you can now use a circular saw anywhere without depending on an electricity supply. The best part? You can work all day long with spare batteries. Plus, you won’t have to deal with cord snags or the loud noise of a generator.
Most trade professionals and serious DIYers consider circular saws essential, so how do you get a valuable cordless saw? Don’t sweat it. We’ve got you covered. Whether you need a professional grade saw or a quality saw for occasional DIY tasks at home, read on for our detailed guide on the best cordless circular saws you can buy in 2022. But you need to first understand the features to consider before shopping for a cordless circular saw.
Features to Consider When Choosing a Circular Saw in 2022
Sidewinder or Worm Drive
The main difference between a sidewinder and a worm drive saw is the location of their motor. A worm drive circular saw has a motor at the rear of the blade, while a sidewinder circular saw has a motor beside the blade.
Why does the location of the motor matter?
Worm drive circular saws have two gears that spin the blade—this design produces less rotation per minute (rpm) but more torque. The maximum speed of a worm drive saw is around 4500 rpm. Contrarily, sidewinder motors have a direct setup with the blades. As a result, the blades spin faster, and the torque is lower than worm drive saws. The maximum speed of sidewinder saws is around 6000 rpm.
The torque difference implies that you should buy a worm drive saw with high torque if you are cutting hard items. However, the design of sidewinder saws is more compact than worm drive saws. Sidewinder saws are easier to use in tight areas than worm drive saws. Sidewinder saws are recommended for beginners because of their compact size.
The limited power of cordless circular saws affects the size of the blades they can handle. The usual blaze size for most cordless circular saws is 6 ½ -inches. Most cordless saws can’t handle 7 ¼ -inches blades like the corded saws. The cutting depth of the 6 ½ -inch blade is 2 ⅛ inches, which is enough for DIY cutting jobs.
The two types of motors in cordless saws are brushed and brushless motors. The main difference you should be worried about is the energy lost to friction in the motors. Brushed motors lose more energy to friction than brushless motors. The high energy requirement reduces the energy efficiency of brushed motors.
The energy efficiency of motors is important in cordless saws because of their batteries. Brushed motors will consume more energy due to the loss of energy to friction. Thus, the batteries of cordless saws with brushed motors will drain faster than the saws with brushless motors. Buying a brushless circular saw will save you more energy, but they are costlier than brushed circular saws.
Although corded circular saws are more powerful than cordless saws, most cordless circular saws have enough power to do any cutting job at home and in workshops. Unless you are a professional that needs more cutting power, most cordless circular saws will cut the materials you have.
Cordless circular saws come with an 18-volt or 20-volt lithium-ion battery because of the significant power needed to rotate their blades. It would be best if you considered the ampere-hour (Ah) rating of the saw’s battery. The run time of batteries increases as the amp hours increase. It is advisable to buy a battery with a large capacity if you plan to do heavy-duty cutting jobs.
To save money, we usually recommend buying into one cordless system and using the batteries across many different tool bodies (skins). That’s why the tools in this article are all ‘skin-only’, which means that you’ll be buying the batteries separately if you don’t have them already.

Safety features you should look out for in cordless circular blades include—retracting blade guards, blade locks, and trigger safeties. These safety features stop the blade and prevent hazardous start-ups when the trigger switch is on. Regardless of the saw’s safety features, ensure you wear protective gear before operating a cordless circular saw.
