Things to Consider in Choosing the Best Cordless Circular Saw

We’ve listed below the considerations to account for when choosing the best Cordless Circular Saw. You should check out the style, blade size, power output and many of its features.

Knowing these things will propel you to the best cordless circular saw for you!

Power Output

Gone were the times when going cordless is not even a consideration because it lacked power compared to corded ones. Battery technology has gone leaps and bounds and the gap between cordless and corded tools has now been closed. It has gone one step further and has produced more powerful saws than corded circular saws.

The standard power rating for circular saws is their rotations per minute (RPM). Majority of the Cordless Circular saws today have ratings between 4,000 RPM to 5,000 RPM for the high-end ones.

Cutting power depends on the RPM ratings. Higher RPM means greater cutting power.

Battery Capacity

Circular saws are expected to perform. Since it requires power, most cordless circular saws are equipped with a rechargeable battery that is either 18-volt or 20-volt lithium-ion.

To make the most out of your investment, manufacturers of the tools design their batteries to work for multiple tools in their lineup of cordless power tools.

Blade Size

The common blade size among the best cordless circular saws is a 6 1/2 inch blade with a maximum cutting depth of 2⅛ inches. The higher-end cordless saws can go as big as a 7 1/4 inch blade with a maximum cutting depth of 2 7/16 inches.

Compact cordless circular saws are equipped with blades that are either 4 1/2 inch and 5 1/2 inch blades.

Sidewinder vs. Worm Drive

This is the most controversial discussion in the world of cordless circular saws. Sidewinder fans and Worm Drive fans have been endlessly comparing each system claiming one is better than the other. Let’s define both of the terms first.

Basically, the main difference between a worm-drive circular saw and a sidewinder is the location of the motor.

With worm-drive circular saws, the motor is attached to the back of the saw. It then engages the blade with two types of gears. The first gear, the spiral worm gear, combined with other gear transfers the power from the motor to the blade.

Due to its design and mechanism, worm-drives produce less RPMs usually at 4500 rpm at the maximum. On the other hand, since the worm drive circular saw utilizes larger gears, it produces more torque. With greater torque, the worm-drive saws can absorb shock better and are more capable in handling tougher cutting tasks.

Sidewinder saws place the motor to the side of the saw. Doing this creates a wider and shorter profile than a worm driven saw. It is also lighter than worm-drive saws.

With its compact design, sidewinder saws have easier handlings which make it ideal even for inexperienced users. To make the blade rotate up to 6000 rpm, sidewinder circular saws use a spur gear in its mechanism.

Brushed vs. Brushless Motor

Friction is the main point of discussion between brushed and brushless motors. A brushless motor produces less friction compared with the brushed motors. Brushless motors rate between 85 to 90 percent in efficiency. On the other hand, brushed motors produce greater friction and rate at 75-80 percent efficiency.

This difference has a great impact on cordless circular saws which run on battery power. Less power is lost to friction with a circular saw that ranks with a higher efficiency rating. All that power not used in dealing with friction goes straight to the blade, maximizing the usage per battery charge.

It is important to note that the most powerful cordless circular saws today use brushless motors. The higher efficiency rating allows the battery to dedicate more power to the blade, creating more torque and producing higher rpms.

Since friction not only takes energy, it also produces more heat. Brushless motors are less likely to overheat because of less friction.

Safety Features

Look for safety features like retracting blade guards, trigger switch that locks the blade in case of emergencies, and automatic shut offs.

Another major safety feature is using a trigger safety to avoid accidental startups. It is also great to look for molded handles and rubber handles for better grip, avoiding accidental slips when operating a powerful machine.

Additional Features

Standard features in corded circular saws are fine adjustments for depth and bevel cuts. Other saws feature waterproof and dustproof components. Other features might just be the factor over choosing one saw from another.
