Best Cordless Circular Saws for 2019
A circular saw is one of the most versatile tools in existence, and it is made only more versatile with the removal of the cord. With a cordless circular saw and two batteries, you can cut nearly everything--anywhere.
Whether you are a seasoned construction worker or weekend DIY enthusiast, a cordless circular saw can decrease the time you are on a job because you do not have to repeatedly plug and unplug the machine. Over the course of a project, this can save a lot of time.
That said, as with any tool, you need to look for certain features. In this case, you should select a cordless saw with the right combination of torque, battery life, and blade size.
Torque involves the amount of spinning power the saw generates in order to drive the blade. A saw with more torque can cut deeper, longer, and cleaner while one with less torque might bind and char the wood.
Additionally, higher torque allows the blade to spin at higher revolutions per minute (RPM), allowing for cleaner cutting across a variety of substrates.
Although you should look for a battery that lasts as long as possible, the actual load time should correlate with charge time.
For instance, it is always recommended that you have two batteries because an extra battery allows you to continue working while your primary battery is charging. The battery life should exceed the charge time, otherwise, your time is wasted.
Blade size involves how deep a cut a saw can make. Blade size is a product of torque. Higher torque will allow for faster blade speed, which allows for bigger blades. Of course bigger blades help you make deeper cuts.
