How To Buy the Best Cordless Circular Saw

When buying your best circular saw, you need to consider blade size, power output, and more features that we discuss below.

a) Type of motor

You can choose from two types of cordless saw motors for your best cordless circular saw;

  1. Sidewinder circular saws
  2. Worm drive circular saws

To differentiate between these two types, you only need to look at the design of the saw. A sidewinder cordless circular saw has its motor on the side. They are usually compact and best for beginners as they are also easier to use.

Additionally, these cordless tools also offer the highest rotation speeds, up to 6000rpm. As such, the saws are better suited for heavy-duty tasks.

A worm drive circular saw, on the other hand, attaches the motor at the back so it can engage the blade through two gears. This design means less energy gets to the blades, often resulting in lower speeds.

b) Power Output

A few years back, we saw corded circular saws as more powerful compared to cordless saws. However, we have welcomed new advancements in the cordless market to ensure cordless models are now just as powerful as corded saws.

Thus, when buying your new cordless circular saw, carefully study the power ratings that are measured in rpm or rotations/revolutions per minute. Most circular saws can offer at least 4000 rpm. As a rule of thumb, a higher rpm shows better cutting power.

However, concerning the type of motor your saw comes with, a higher rpm does not mean a higher torque. All the saws with their motor attached at the back will have a lower rpm, but they will also come with higher torque.

c) Battery and battery life

You will want a strong battery for any cordless saw you buy. It is a power tool that you need running for as long as possible.

You can choose any with a rechargeable battery from 18V and higher. Some models need more power, like the Makita from this list which uses two 18V batteries, thus 36 volts of power. As you will find from most manufacturers, you can use the saw batteries to power other tools like leaf blowers, hedge trimmers, and more.

To preserve battery life, you can look for models with brushless motors which produce less friction. You can understand how best your best cordless circular motor will perform by looking at the efficiency rating that will be between 85 to 90 percent.

A brushed motor will produce more friction, thus gaining a lower efficiency rating and not promoting enough power-saving abilities. Additionally, they will produce more heat because of the friction, which could eventually lead to overheating.

d) Blades

One major shortcoming of choosing a cordless saw over a corded circular saw is the batteries can not provide as much power as electricity does. Thus, these circular saws will come with smaller blades.

When buying the power tools, you need to consider how strong the batteries are so you can pick the proper blade size. Most cordless circular saws come with 6.5-inch blades, while others go lower to 5.5 inches. A few pro tools will feature a 7 1/4 blade diameter.

Safety When Using the Best Cordless Circular Saws

  1. Before cutting with the cordless saw, the first thing to do is to observe your safety. Make sure to wear your proper safety gear like gloves and safety glasses to prevent dust from flying into your eyes.
  2. When using your best cordless saws, ensure to install the blade properly. As important, ensure you have the proper blade for the kind of cutting you want to perform.
  3. Once your correct blade is properly installed, calibrate the cutting depth and the bevel angle for the shapes and materials you want to cut. Also, ensure your retractable blade guards are in place before cutting.
  4. Observe the model features to operate the tool safely. These include which hand to use; each tool is either blade left or blade right, the location of the trigger, and more. You can also attach an external dust blower for some models to prevent dust from covering your cut line. Once you know what to do, you can safely cut your materials into desired designs.
