Cordless circular saws offer you a lot of versatility and maneuverability on whatever job you are using them on. While you can buy them with or without batteries, this list all has a battery included. After all, unless you have been collecting them for a long time, you are likely going to need new batteries.
When looking at an overall best product, the cost vs. the features is one of the critical points. The DeWalt Max is a workhorse with a five amp hour battery and charger in the set. The 5,200 RPM motor is powerful enough for any job, and the big battery should last you all day too. The blade has an excellent 57-degree tilt available for beveling as well.
Made to last
While this isn't the best overall because of the price, it is my favorite saw of the bunch. Makita makes excellent tools that last a long while, and this saw is no exception. This set comes with two five amp-hour (5Ah) batteries for maximum usage time, and the build quality is outstanding. If you have the money, you should consider this.
For those of us who need to pinch the pennies, but who need a saw that will do the job, the Black + Decker 20v is a great deal. The high-torque motor is backed up by a two-year warranty, which is excellent and at this low price and supplies you with a battery that works across the whole Black + Decker range. It's the batteries that cost the most after all, so getting one cheap is a big help.
Versatile for spaces small and large
Sometimes you don't need a tremendous hulking saw to get the job done. For smaller jobs, like flooring or roofing, you may want something with a little more control. This small Makita is perfect for those small jobs and uses the same powerful batteries that its bigger brothers use. Being able to use it safely with one hand is a huge bonus too.
There are a lot of cordless saws out there, but only a few different brands are established enough to guarantee access to the batteries for the of the tool. With the DeWalt 20v Max you have the security of knowing the company has been around for a long time and is well known for taking care of its tools for a long while. The saw is also that perfect balance of cost and utility.
