What to Consider When Choosing the Best Cordless Circular Saw

A few things to consider when shopping for a cordless circular saw include style, power output, blade size, and features.

Sidewinder vs. Worm Drive

Sidewinder versus worm drive is one of the most hotly debated topics in the world of woodworking. Let’s take a closer look.

Worm-drive circular saws and sidewinder saws differ mainly in the placement of the motor. A worm drive’s motor attaches to the back of the saw and engages with the blade via two gears—the spiral “worm” gear and another gear—which transfers the motor’s energy to the blade.

Because this setup is less direct, most worm-driven blades do not spin as fast as sidewinder blades, hitting maximum speeds of only around 4,500 rpm. A worm drive saw uses larger gears, which gives it more torque than a sidewinder, allowing it to absorb shock better and take on tougher cutting jobs.

Worm drives have a longer and narrower profile than sidewinder circular saws, which extends the operator’s reach and allows access to tighter spaces. This makes them ideal for jobs like remodeling and framing.

Sidewinder saws have their motors on the saw side, which makes their profile wider, shorter, and lighter than a worm drive saw. This compact shape makes the saw easier to handle and better-suited for inexperienced users. Sidewinder saws use a spur-gear to turn the blade at speeds close to 6,000 rpm.


It used to be that cordless circular saws were less powerful than corded varieties. Thanks to advancements in battery technology, the power gap has closed dramatically. In fact, many cordless circular saws have more battery life than corded circular saws.

Circular saws’ power rating is measured in rotations per minute (rpm). Most cordless circular saws have 4,000 rpm, with higher-end saws boasting 5,000 rpm or more. The higher the rpms, the better the cutting power. Keep in mind that rpms are not necessarily a good indication of torque. Though a worm drive saw may have lower rpm than a sidewinder saw, its design gives it more torque.


Given the substantial power requirements of a circular saw, cordless circular saws feature a rechargeable 18-volt or 20-volt lithium-ion battery that attaches to the saw. Many manufacturers design their batteries to work interchangeably with their entire cordless power tools lineup, including cordless circular saws.

Makita Circular Saw Blade


Blade Size

Because cordless circular saws usually don’t have as much power as corded saws, most can’t handle a full 7 1/4-inch blade. While smaller blades will produce more torque because they are easier for the motor to turn, they are limited in cutting depth.

The majority of cordless circular saws feature 6 1/2-inch blades, although a few high-end saws use 7 1/4-inch blades. A 6 1/2-inch blade offers a maximum cutting depth of 2 1/8 inches, while a larger 7 1/4-inch blade can cut to a depth of 2 7/16 inches. Smaller cordless circular saws will feature both 5 1/2-inch blades and even 4 1/2-inch blades.

Brushed vs. Brushless Motor

The main difference between brushed and brushless motors has to do with friction. Without going into the mechanics of how each motor works, a brushless motor produces less friction, resulting in an efficiency rating of between 85 and 90 percent. In comparison, brushed motors lose more energy to friction, resulting in 75 to 80 percent efficiency.

While this difference may not amount to much for corded circular saws that have access to a limitless supply of 110-volt power, it has a significant impact on cordless saws. The higher the efficiency rating, the less energy is lost to friction, which means more of the battery’s power goes toward turning the saw blade. This equates to more cuts before the battery loses its charge.

A higher efficiency rating also means a 20-volt battery can dedicate more power to turning the blade, resulting in more torque and higher maximum rpm. The most powerful cordless circular saws, including those capable of turning 7 1/4-inch blades, use brushless motors.

Also, because these power tools produce less friction, brushless motors create less heat, which reduces the likelihood of overheating that could damage the motor.

Safety Features

Cordless circular saws feature similar safety features to corded saws, including retracting blade guards and blade locks that immediately stop the blade once the trigger switch is released.

Cordless circular saws also use trigger safeties to prevent accidental start-ups. Other safety features include molded handles with rubberized grips that prevent the tool from slipping out of the operator’s hands.

Additional Features

In addition to standard features such as bevel angle and depth adjustments, cordless circular saws also offer new technologies designed to extend the saw’s life. Some saws will shut off if the saw is overheating or if the battery is close to overloading.

Higher-end saws have waterproof seals that resist water and dust, allowing them to withstand the harsh environment of an outdoor worksite. Some saws will even automatically adjust torque and speed based on the workload to optimize performance.

Tips for Using a Cordless Circular Saw

One important thing to do is choose the proper saw blade for your cordless circular saw. This goes beyond just selecting the appropriate size. There are many different types of blades designed to cut different materials, from rip blades to cross-cut blades to general purpose blades. Choosing the right blade is key to making successful cuts.

Once you’ve selected the proper blade, follow the manufacturer’s instructions for proper blade installation. This typically involves removing the 5/8-inch bolt holding the blade to the drive with a wrench. Make sure the blade is facing the right direction. Most blades have an arrow printed on them, delineating its proper rotation direction.
Cordless circular saws feature depth gauges and bevel adjustments. Make sure to calibrate these features for the cut you’re making.

Before operating a cordless circular saw, make sure you have the proper safety gear, including safety glasses. Except for smaller 4 1/2-inch cordless circular saws or hand-held saws, most cordless circular saws require two hands for safe use: a handle that includes the trigger and a knob-like grip toward the front of the unit. This allows for optimal control of the saw while preventing fingers from getting in the blade’s path. Finally, make sure the retractable guard is in place before cutting.

Because a cordless circular has its own power source, it’s free to go wherever it’s needed. To get the best performance out of a cordless circular saw, it’s essential to follow some important safety and operation guidelines.

  • Choose the right blade
  • Install the blade correctly
  • Calibrate the proper depth and bevel angle
  • Wear the proper safety gear
  • Operate the saw safely


Below we’ll address some of the most commonly asked questions about cordless circular saws.

Q: How do cordless circular saws work?

As with a corded circular saw, a cordless saw works using a small motor to power a circular blade. While a corded saw is powered by direct current electricity from a standard electrical outlet, a cordless circular saw uses an 18- or 20-volt battery attached to the saw.

Q: Why are most cordless saws left handed?

Most cordless circular saws have left-side blades, which means the motor and the bulk of the weight are on the right side. Because of this configuration, the trigger handle is held with the left hand and the stabilizing knob on the front of the saw is held with the right hand. This design maximizes visibility, allowing the operator to get a clear view of the cut line.

Q: How long does a cordless circular saw last?

Manufacturers rate saws by the number of cuts they can make before needing a recharge. While this is difficult to measure, given that different materials and different cuts demand different amounts of power, a standard cordless circular saw can make as many as 300 cuts on a single charge.
