Best Cordless Circular Saw Buying Guide:
There are multiple things that you need to consider when choosing the best cordless circular saw for yourself. Here are the things that you need to keep in mind:
The powers of the cordless circular saws weren’t much back in the days. However, with the advancement of batteries, now we can get almost equivalent power as the corded circular saws.
When you’re choosing circular saws, power is very important. The power is usually measured in rpm, and you’ll find a lot of variety when it comes to power.
The rpm isn’t everything, and this is something you need to keep in mind. You need to make sure that the saw has a decent rpm, about 4000 is fine. Some boast 5000 rpm as well, but you need to ensure that they have a high torque as well. Otherwise, it won’t be able to cut through anything.
Type of Saw:
There are two types of saws. There’re the Sidewinder saws. These saws usually offer a faster rpm, which allows them to cut through the planks fast. On the other hand, there are the worm drives. The worm drives offer more torque, but less rpm speed.
Another striking difference between these is that the sidewinder is quite bulky and wide, while the worm drive is narrow and long. This is why you’ll be able to reach narrower places with the worm drive. However, the sidewinder, being much wider, is much easier to handle. This makes them more suitable for newer users.
The battery determines how long you’ll be able to use the saw at a certain speed. If the battery is rated 18V or 20V, you’re good to go.
Brushed vs. Brushless Motors:
You’ll find two types of motors on the market. There are brushed motors. These motors come with more friction, which makes them a bit inefficient. On the other hand, there are brushless motors. These are much more efficient than the brushed motors, as they come with lesser friction.
While you might get an efficiency rating of 75 to 80 percent from the brushed motors, you’ll get an efficiency rating of 85 to 90 percent from the brushless motors.
This is why we highly recommend getting the brushless motors.
Now that we’re at the end of our article, hopefully, you were able to understand more about circular saws. Now, it’s time for the verdict.
Among all the cordless circular saws that we reviewed; we found the Makita XSS02Z as the best one that you can get. Sure, this saw doesn’t offer a whopping 48V motor. However, most people won’t need that. You’ll get a great combination of battery, power, balance, and build quality from this tool.
This is why we highly recommend getting the Makita XSS02Z cordless circular saw. However, your choice depends completely on your preferences. So, you need to see what suits you the best, and you need to go with that tool.
